The function of surfactant is to? A. transport the oxygen from the air to the blood, B. transport the carbon dioxide from the blood to the air, C. prevent each alveolus from collapsing as air moves in and out during respiration, D. trap foreign particles as they enter the bronchial tree
Homework Answers
option c ; prevent each alveolus from collapsing as air moves in and out during respiration .
as te surfactant lowers the surface tension ,each alveoli has surfactant coated it reduces the surface tension , the force of attarction between the molecule ,this from prevents alveoli from collapsing and sticking shut as air moves in and out during respiration

Which of the following explains why the PO2 of the blood leaving pulmonary capillaries is 104 mm Hg, but the blood leaving the lungs to enter the left atrium is 95 mm Hg? Some oxygen diffuses out of the blood as it travels through the pulmonary veins. Some carbon dioxide in the alveoli is mixed with oxygenated blood from alveolar circulation. Some carbon dioxide in the alveoli is mixed with oxygenated blood from alveolar circulation. Some oxygen is incorporated into...
