Alveolar Gas Exchange Flashcards
What is the primary function of alveolar gas exchange?
To exchange oxygen and carbon dioxide between air and blood
In which structures does gas exchange occur?
Between alveoli and capillaries
What happens to oxygen during alveolar gas exchange?
Oxygen moves from the alveoli into the blood, causing blood to become oxygenated
What happens to carbon dioxide during alveolar gas exchange?
Carbon dioxide moves from the blood into the alveoli to be exhaled
How do oxygen and carbon dioxide move during gas exchange?
Via diffusion down the concentration gradient
Fill in the blank: Gas exchange occurs in the _______.
[alveoli]
True or False: Blood becomes oxygenated after carbon dioxide moves into the alveoli.
False
What type of blood is delivered to the alveoli via the pulmonary artery?
Venous blood
What is the role of red blood cells in capillaries during gas exchange?
To transport oxygen and carbon dioxide
