Respiratory System Anatomy
This structure is known as the "voice box"
Larynx
Inhalation
A method that measures volume of air moved during inspiration and expiration
spirometry
cartilaginous ridge at the point where the trachea (windpipe) divides into the right and left main bronchi
Carina
Nasopharynx (behind the nose), the Oropharynx (behind the mouth), and the Laryngopharynx
Before inhalation the pressure outside the body is ______ than inside the body
Rate of respirations is primarily controlled
Medulla Oblongata and Pons
Volume of air inhaled and exhaled during normal breathing
Tidal Volume
What are the two cells inside the alveoli and their function
Type I Alveolar Cells, involved in gas exchange
Type II Alveolar Cells, Produce surfactant, prevents collapse and overexpansion
Epiglottis
What parts of the respiratory system does air travel through reach the blood
Nasal Cavity, pharynx, larynx, trachea, bronchi, bronchioles
Factors Affecting Oxygen Unloading
Po2 is low
Pco2 is high
pH is low
Temperature is high
Amount of air able to be inhaled after normal inhalation
Inspiratory reserve volume
Carbon dioxide transport in the capillaries.
What CO2 forms when it diffuses in the red blood cell?
Then, it splits into ____ and ____
What is chloride shift?
Carbonic acid (H2CO3).
Bicarbonate (HCO3-) and H+
Bicarbonate leaves the cell and CL- enters the RBC, preventing excess of negative charge.
Hollow areas between the bones in your head that helps regulate the temperature and humility of the air you inhaled
Sinuses
Air flow through the Lower Respiratory Tract
Conducting zone:
Larynx, trachea, Main bronchi, Lobar bronchi, Segmental bronchi, Bronchioles, Terminal Bronchioles
Gas Exchange:
Respiratory bronchioles, alveolar ducts, alveolar sacs, Alveoli
Factors Affecting Oxygen Loading
Po2 is high
Pco2 is low
Temperature is low
pH is high
Amount of air able to be inhaled after normal exhalation
Expiratory reserve volume
State the Boyle's law
volume and pressure are inversely related.
It forms the lower and posterior parts of the wall of the larynx.
Cricoid Cartilage
Air flow through the Upper Respiratory Tract
Nose, Nasal Cavity, nasopharynx , oropharynx , laryngopharynx.
amount of air left in the lungs after maximum exhalation
Residual volume
Total Volume of air able o be forcefully inhaled and exhaled
Vital Capacity
Who discover the law of partial pressure? And what it states?
John Dalton, pressure exerted by each gas within mixture of gases.
