Respiratory System

Respiratory system functions of the respiratory system to supply the body with oxygen and dispose of carbon dioxide respiration four distinct processes must ... – powerpoint ppt presentation.

• To supply the body with oxygen and dispose of carbon dioxide
• Respiration four distinct processes must happen
• Pulmonary ventilation moving air into and out of the lungs
• External respiration gas exchange between the lungs and the blood
• Transport transport of oxygen and carbon dioxide between the lungs and tissues
• Internal respiration gas exchange between systemic blood vessels and tissues
• Consists of the conducting and respiratory zones
• Respiratory muscles diaphragm and other muscles that promote ventilation
• Conducting zone
• Provides rigid conduits for air to reach the sites of gas exchange
• Includes nose, nasal cavity, pharynx, trachea
• Air passages undergo 23 orders of branching in the lungs
• Respiratory zone - site of gas exchange
• Consists of bronchioles, alveolar ducts, and alveoli
• Approximately 300 million alveoli
• Account for most of the lungs volume
• Provide tremendous surface area for gas exchange
• Internal respiration - exchange of gases between interstitial fluid and cells
• External respiration - exchange of gases between interstitial fluid and the external environment
• The steps of external respiration include
• Pulmonary ventilation
• Gas diffusion
• Transport of oxygen and carbon dioxide
• The physical movement of air into and out of the lungs
• A mechanical process that depends on volume changes in the thoracic cavity
• Volume changes lead to pressure changes, which lead to the flow of gases to equalize pressure
• Boyles law the relationship between the pressure and volume of gases
• P pressure of a gas in mm Hg
• V volume of a gas in cubic millimeters
• Inversely proportional - in other words
• as pressure decreases, volume increases
• as volume decreases, pressure increases
• Respiratory pressure is always described relative to atmospheric pressure
• Atmospheric pressure (pATM)
• Pressure exerted by the air surrounding the body
• Negative respiratory pressure is less than pATM
• Positive respiratory pressure is greater than pATM
• Intrapulmonary pressure pressure within the alveoli 760mmHg
• Intrapleural pressure pressure within the pleural cavity 756mmHg
• Two forces hold the thoracic wall and lungs in close apposition stretching the lungs to fill the large thoracic cavity
• Intrapleural fluid cohesiveness polarity of water attracts wet surfaces
• Transmural pressure gradient pATM (760mmHg) is greater than intrapleural pressure (756mmHg) so lungs stay expand
• Intrapulmonary pressure and intrapleural pressure fluctuate with the phases of breathing
• Intrapulmonary pressure always eventually equalizes itself with atmospheric pressure
• Intrapleural pressure is always less than intrapulmonary pressure and atmospheric pressure
• Changes in intra-alveolar pressure produce flow of air into and out of the lungs
• If this pressure is less than atmospheric pressure, air enters the lungs. If the opposite occurs, air exits from the lungs.
• Boyles law states that at any constant temperature, the pressure exerted by a gas varies inversely with the volume of a gas.
• The diaphragm and external intercostal muscles (inspiratory muscles) contract and the rib cage rises
• The lungs are stretched and intrapulmonary volume increases
• Intrapulmonary pressure drops below atmospheric pressure (?1 mm Hg)
• Air flows into the lungs, down its pressure gradient, until intrapulmonary pressure atmospheric pressure
• Inspiratory muscles relax and the rib cage descends due to gravity
• Thoracic cavity volume decreases
• Elastic lungs recoil passively and intrapulmonary volume decreases
• Intrapulmonary pressure rises above atmospheric pressure (1 mm Hg)
• Gases flow out of the lungs down the pressure gradient until intrapulmonary pressure is equalized
• Single cycle of inhalation and exhalation
• Amount of air moved in one cycle tidal volume
• Friction is the major nonelastic source of resistance to airflow
• The relationship between flow (F), pressure (P), and resistance (R) is
• Compliance - ability to stretch, the ease with which lungs can be expanded due to change in transpulmonary pressure
• Determined by two main factors
• Distensibility of the lung tissue and surrounding thoracic cage
• Surface tension of the alveoli
• High compliance - stretches easily
• Low compliance - Requires more force
• Elastic recoil - returning to its resting volume when stretching force is released
• Elasticity of connective tissue causes lungs to assume smallest possible size
• Surface tension of alveolar fluid draws alveoli to their smallest possible size
• Elastance measure of how readily the lungs rebound after being stretched
• Surface tension the attraction of liquid molecules to one another at a liquid-gas interface, the thin fluid layer between alveolar cells and the air
• This liquid coating the alveolar surface is always acting to reduce the alveoli to the smallest possible size
• Surfactant, a detergent-like complex secreted by Type II alveolar cells, reduces surface tension and helps keep the alveoli from collapsing
• Airway Resistance - Gas flow is inversely proportional to resistance with the greatest resistance being in the medium-sized bronchi, Severely constricted or obstructed bronchioles COPD
• Lungs can be filled to over 5.5 liters on max inspiratory effort
• Emptied to 1 liter on max expiratory effort
• Normally operate at half full 2-2.5 liters
• On average 500ml is moved in and out with each breath
• Tidal volume (TV) air that moves into and out of the lungs with each breath (approximately 500 ml)
• Inspiratory reserve volume (IRV) air that can be inspired forcibly beyond the tidal volume (21003200 ml)
• Expiratory reserve volume (ERV) air that can be evacuated from the lungs after a tidal expiration (10001200 ml)
• Residual volume (RV) air left in the lungs after strenuous expiration (1200 ml)
• Inspiratory capacity (IC) total amount of air that can be inspired after a tidal expiration (IRV TV)
• Functional residual capacity (FRC) amount of air remaining in the lungs after a tidal expiration (RV ERV)
• Vital capacity (VC) the total amount of exchangeable air (TV IRV ERV)
• Total lung capacity (TLC) sum of all lung volumes (approximately 6000 ml in males)
• Anatomical dead space volume of the conducting respiratory passages (150 ml)
• Alveolar dead space alveoli that cease to act in gas exchange due to collapse or obstruction
• Total dead space sum of alveolar and anatomical dead spaces
• Factors influencing the movement of oxygen and carbon dioxide across the respiratory membrane
• Partial pressure gradients and gas solubilities
• Matching of alveolar ventilation and pulmonary blood perfusion
• Structural characteristics of the respiratory membrane
• Total pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture
• The partial pressure of each gas is directly proportional to its percentage in the mixture
• The partial pressure of oxygen (PO2)
• Air is 20.93 oxygen
• Total pressure of air 760 mmHg
• PO2 0.2093 x 760 159 mmHg
• When a mixture of gases is in contact with a liquid, each gas will dissolve in the liquid in proportion to its partial pressure
• The amount of gas that will dissolve in a liquid also depends upon its solubility
• Various gases in air have different solubilities
• Carbon dioxide is the most soluble
• Oxygen is 1/20th as soluble as carbon dioxide
• Nitrogen is practically insoluble in plasma
• Gases diffuse from high ? low partial pressure
• Between lung and blood
• Between blood and tissue
• Ficks law of diffusion
• V gas A x D x (P1-P2)
• V gas rate of diffusion
• A tissue area
• T tissue thickness
• D diffusion coefficient of gas
• P1-P2 difference in partial pressure
• Are only 0.5 to 1 ?m thick, allowing for efficient gas exchange
• Have a total surface area (in males) of about 60 m2 (40 times that of ones skin)
• This air-blood barrier is composed of alveolar and capillary walls
• Alveolar walls are a single layer of type I epithelial cells
• The atmosphere is mostly nitrogen 79 oxygen 21, only 0.03 is CO2
• Alveoli contain more CO2 and water vapor
• These differences result from
• Gas exchanges in the lungs oxygen diffuses from the alveoli and carbon dioxide diffuses into the alveoli
• Humidification of air by conducting passages
• The mixing of alveolar gas that occurs with each breath
• Based on Daltons law, partial pressure of alveolar oxygen is 100mmHG and partial pressure of alveolar CO2 is 40mmHg
• The partial pressure of oxygen (PO2) of venous blood is 40 mm Hg the PO2 in the alveoli is 100 mm Hg
• Steep gradient allows PO2 gradients to rapidly reach equilibrium (0.25sec)
• Blood can move quickly through the pulmonary capillary and still be adequately oxygenated
• Although carbon dioxide has a lower partial pressure gradient 40 -gt 46
• It is 20 times more soluble in plasma than oxygen
• It diffuses in equal amounts with oxygen
• The factors promoting gas exchange between systemic capillaries and tissue cells are the same as those acting in the lungs
• The partial pressures and diffusion gradients are reversed
• PO2 in tissue is always lower than in systemic arterial blood
• PO2 of venous blood draining tissues is 40 mm Hg and PCO2 is 45 mm Hg
• Overview of Partial Pressure Gradients
• Ventilation the amount of gas reaching the alveoli
• Perfusion the blood flow reaching the alveoli
• Ventilation and perfusion must be tightly regulated for efficient gas exchange
• Changes in PCO2 in the alveoli cause changes in the diameters of the pulmonary arterioles
• Alveolar CO2 is high/O2 low vasoconstriction
• Alveolar CO2 is low/O2 high vasodilation
• Dissolved in plasma
• Bound to hemoglobin (Hb) for transport in the blood
• Oxyhemoglobin O2 bound to Hb (HbO2)
• Deoxyhemoglobin O2 not bound to (HHb)
• Carrying capacity
• 201 ml O2 /L blood in males
• 150 g Hb/L blood x 1.34 ml O2 / /g of Hb
• 174 ml O2 /L blood in females
• 130 g Hb/L blood x 1.34 mlO2/g of Hb
• Saturated hemoglobin when all four hemes of the molecule are bound to oxygen
• Partially saturated hemoglobin when one to three hemes are bound to oxygen
• Rate that hemoglobin binds and releases oxygen is regulated by
• Temperature
• 2,3 DPG (an organic chemical)
• Hemoglobin saturation plotted against PO2 produces a oxygen-hemoglobin dissociation curve
• At 100mmHg, hemoglobin is 98 saturated
• Saturation of hemoglobin is why hyperventilation has little effect on arterial O2 levels
• In fact, hemoglobin is almost completely saturated at a PO2 of 70 mm Hg
• Further increases in PO2 produce only small increases in oxygen binding
• Oxygen loading and delivery to tissue is still adequate when PO2 is below normal levels
• 98 saturated arterial blood contains 20 ml oxygen per 100 ml blood (20 vol )
• Only 2025 of bound oxygen is unloaded during one systemic circulation
• As arterial blood flows through capillaries, 5 ml oxygen/dl are released
• If oxygen levels in tissues drop
• More oxygen dissociates from hemoglobin and is used by cells
• Respiratory rate or cardiac output need not increase
• Temperature, H, PCO2, and BPG alter its affinity for oxygen
• Increases of these factors decrease hemoglobins affinity for oxygen and enhance oxygen unloading from the blood
• H and CO2 modify the structure of Hb - Bohr effect
• DPG produced by RBC metabolism when environmental O2 levels are low
• These parameters are all high in systemic (tissue) capillaries where oxygen unloading is the goal
• Factors contributing to the total oxygen content of arterial blood
• Carbon dioxide is transported in the blood in three forms
• Dissolved in plasma 7 to 10
• Chemically bound to hemoglobin 20 is carried in RBCs as carbaminohemoglobin
• Bicarbonate ion in plasma 70 is transported as bicarbonate (HCO3)
• Carbon dioxide diffuses into RBCs and combines with water to form carbonic acid (H2CO3), which quickly dissociates into hydrogen ions and bicarbonate ions
• In RBCs, carbonic anhydrase reversibly catalyzes the conversion of CO2 and water to carbonic acid
• The carbonic acidbicarbonate buffer system resists blood pH changes
• If H in blood increases, excess H is removed by combining with HCO3
• If H decrease, carbonic acid dissociates, releasing H
• At the tissues bicarbonate quickly diffuses from RBCs into the plasma
• The chloride shift to counterbalance the out rush of negative bicarbonate ions from the RBCs, chloride ions (Cl) move from the plasma into the erythrocytes
• At the lungs, these processes are reversed
• Bicarbonate ions move into the RBCs and bind with hydrogen ions to form carbonic acid
• Carbonic acid is then split by carbonic anhydrase to release carbon dioxide and water
• Carbon dioxide then diffuses from the blood into the alveoli
• Removing O2 from Hb increases the ability of Hb to pick up CO2 and CO2 generated H is called the Haldane effect.
• The Haldane and Bohr effect work in synchrony to facilitate O2 liberation and uptake of CO2 and H
• At the tissues, as more CO2 enters the blood
• More oxygen dissociates from Hb (Bohr effect)
• Unloading O2 allows more CO2 to combine with Hb (Haldane effect), and more bicarbonate ions are formed
• This situation is reversed in pulmonary circulation
• Dorsal respiratory group (DRG), or inspiratory center
• Inspiratory neurons
• Thought to set by basic rhythm pacemaking (now believed to be pre-Botzinger complex)
• Excites the inspiratory muscles and sets eupnea (12-15 breaths/minute)
• Cease firing during expiration
• Ventral respiratory group (VRG)
• Inspiratory expiratory neurons
• Remains inactive during quite breathing
• Activity when demand is high
• Involved in forced inspiration and expiration
• Control via phrenic and intercostal nerves
• Pontine respiratory group (PRG) influence and modify activity of the medullary centers to smooth out inspiration and expiration transitions
• Pneumotaxic center sends impulses to DRG to switch off inspiratory neurons, limiting duration of inspiration
• Apneustic center prevents inspiratory inhibition to provide increase inspiratory drive when needed
• Pneumotaxic dominates to allow expiration to occur normally
• Inspiratory depth is determined by how actively the respiratory center stimulates the respiratory muscles
• Rate of respiration is determined by how long the inspiratory center is active
• Respiratory centers in the pons and medulla are sensitive to both excitatory and inhibitory stimuli
• Cortical controls are direct signals from the cerebral motor cortex that bypass medullary controls
• Examples voluntary breath holding, taking a deep breath
• Hypothalamic controls act through the limbic system to modify rate and depth of respiration
• A rise in body temperature acts to increase respiratory rate
• Pulmonary irritant reflexes irritants promote reflexive constriction of air passages
• Inflation reflex (Hering-Breuer)
• Upon inflation, inhibitory signals from stretch receptors are sent to the medullary inspiration center to end inhalation and allow expiration
• Though a rise CO2 acts as the original stimulus, control of breathing at rest is regulated by the hydrogen ion concentration in the brain
• Changing PCO2 levels are monitored by chemoreceptors of the brain stem
• As PCO2 levels rise in the blood, it diffuses into the cerebrospinal fluid where it is hydrated resulting carbonic acid
• Carbonic acid dissociates releasing hydrogen ions decreasing pH results in increased depth and rate of breathing
• Peripheral chemoreceptors
• Located in carotid and aortic arteries
• Specialized glomus cells
• Sense changes in PO2, pH, and PCO2
• Hyperventilation increased depth and rate of breathing that
• Quickly flushes carbon dioxide from the blood
• Occurs in response to hypercapnia
• Hypoventilation slow and shallow breathing due to abnormally low PCO2 levels
• Apnea (breathing cessation) may occur until PCO2 levels rise
• Arterial oxygen levels are monitored by the aortic and carotid bodies
• Substantial drops in arterial PO2 (to 60 mm Hg) are needed before oxygen levels become a major stimulus for increased ventilation
• If carbon dioxide is not removed (e.g., as in emphysema and chronic bronchitis), chemoreceptors become unresponsive to PCO2 chemical stimuli
• In such cases, PO2 levels become the principal respiratory stimulus (hypoxic drive)
• Changes in arterial pH can modify respiratory rate
• If pH is low, respiratory system controls will attempt to raise the pH by increasing rate and depth of breathing
• Increased ventilation in response to falling pH is mediated by peripheral chemoreceptors
• Acidosis may reflect
• Carbon dioxide retention
• Accumulation of lactic acid
• Excess fatty acids in patients with diabetes mellitus
• If pH is high, respiratory system controls will attempt to lower pH by decreasing rate and depth of breathing

THE HUMAN RESPIRATORYSYSTEM

Aim: How do the structures of the respiratory system exchange gases with the environment? • Do Now: What is the purpose of having a respiratory system? • Homework: Read 574-576; do Self Check Questions # 1-4.

What is Respiration? Respiration: the process of exchanging gases between the body and the environment.

What is a Respiratory Surface? • In all organisms, the exchange of gases must occur across a respiratory surface. • Must be moist • Must be very thin so that gases are able to pass through • Must be a supply of oxygen • Must be closely connected to the transport system to deliver gases to and from cells

The Human Respiratory System

Organs of the Respiratory System

The Nose • The nose serves to filter, moisten, and warm inhaled air before it reaches the lungs.

What is the Pharynx? • Pharynx – “throat” • Air moves from the nasal passage  the pharynx • Epiglottis – flap of tissue covering the trachea during swallowing preventing food from entering the lungs.

The Larynx • “voice box” • Larynx contains vocal cords used to speak. • Air passes from the pharynx  larynx • Food passes from the pharynx  esophagus

The Trachea • “the windpipe” • Kept open by rings of cartilage • Lined with cilia and mucous membranes

Aim: How do the structures of the respiratory system allow you to breathe? • Do Now: What does the nose do to the air that you breathe? What is the role of the cilia that line the trachea? • Homework:

The Bronchi • Trachea divides into tubes called the bronchi • Bronchi enter lungs and branch off into tiny tubes called bronchial tubes

The Bronchioles • AKA: Bronchial Tubes • Thin network of microscopic tubes found inside the lungs.

Alveoli: The Air Sacs

Alveoli: The Air Sacs • Found in the LUNGS • Each bronchiole ends in a tiny alveoli • “cluster of grapes” • The alveoli are the respiratory surface • Exchange of O2 and CO2 occurs HERE! • Alveoli are surrounded by capillaries (so O2 enters blood).

Gas Exchange

Aim: How do the structures of the respiratory system work together to allow you to breathe? • Do Now: Explain how gas exchange occurs in the lungs • Homework:

How do we Breathe?

What is Going on Inside When You Breathe? • Composed of two phases: • Inhalation – draws air into lungs • Exhalation – expels air from lungs

What is the Diaphragm? • Muscle that contracts and relaxes to move gas into and out of the lungs.

Inhalation • Ribs are pulled up and out • Diaphragm is pulled downward • Chest cavity is enlarged • Lungs expand • Air pressure in chest decreases

Exhalation • Diaphragm relaxes and pushes upward • Rib muscles relax – ribs drop • Size of chest cavity decreases • Air is squeezed out of lungs • Air pressure in chest increases

Rate of Breathing • If CO2 levels in the blood increase, your breathing rate INCREASES. • If CO2 levels decrease, breathing rate DECREASES.

Aim: What are the malfunctions of the human respiratory system? • Do Now: Is it INHALATION or EXHALATION? • The ribs are pulled up and out, the diaphragm is pulled down. ___________ • The lungs decrease in size, the diaphragm is pushed upward. __________________ • The chest cavity decreases in size, the pressure inside the chest increases. ________________ • Homework:

DISEASES OF THE RESPIRATORY SYSTEM

Asthma • Severe allergic reaction where muscles surrounding bronchial tubes contract and make breathing extremely difficult.

Bronchitis • Inflammation of the bronchial tubes • Passageways become swollen and clogged with mucus • Results in severe coughing and difficulty in breathing

Emphysema • Walls of alveoli breakdown decreasing the respiratory surface • Causes shortness of breath, difficulty exhaling and decreased lung capacity *Smokers run a greater risk of developing emphysema*

Pneumonia • Alveoli become filled with fluid • Caused by a bacterial or viral infection

Lung Cancer • Disease in which tumors form in the lungs from irregular and uncontrolled cell growth

Let’s Summarize… • What happens during respiration in all animals? • What are the requirements of a respiratory surface? • How are dirt and other small particles removed from the air humans breathe? • List in order the structures that air passes through as it travels from the external environment to the lungs.

Let’s Summarize… 5. Why are cilia important to the function of the lungs? • At what point does the oxygen that you inhale actually enter into your blood? • What happens to the rib cage during inhalation and exhalation? • What happens to the diaphragm during inhalation and exhalation?

Let’s Summarize 9. What system of the body carries the oxygen taken in by the respiratory system to all cells in the body? 10. What is the scientific term for the “back of the throat”? 11. What is the role of mucous in the respiratory system?

What Should We Study? • Be able to : • Define all vocabulary in the respiratory system – including structures • Trace a drop of air from environment to the alveoli in the lungs. • Label diagrams of the respiratory system. • Explain a malfunction of the respiratory system and what causes it. • Explain the function of each of the structures in the respiratory system. • Discuss what makes a good respiratory surface – and where our respiratory surface is found.
