Which of the following statement is true?
(a) Every 100 mL of deoxygenated blood delivers approximately 4 mL of carbon dioxide to the alveoli.
(b) Every 100 mL of oxygenated blood delivers approximately 4 mL of oxygen to the tissues.
(c) Every 100 mL of oxygenated blood delivers approximately 4 mL of carbon dioxide to the alveoli.
(d) Every 100 mL of deoxygenated blood delivers approximately 10 mL of carbon dioxide to the alveoli.
Correct answer: (a) Every 100 mL of deoxygenated blood delivers approximately 4 mL of carbon dioxide to the alveoli.
Explanation:
Every 100 mL of deoxygenated blood delivers approximately 4 mL of carbon dioxide to the alveoli.
Every 100 mL of oxygenated blood delivers approximately 5 mL of oxygen to the tissues under normal physiological conditions.
