What function do the alveoli perform?(1 point)
Responses
hold receptors for the sense of smell
carry oxygenated blood away from the heart
exchange oxygen in the air for carbon dioxide in the blood
exchange oxygen in the blood for carbon dioxide in the air
The function of the alveoli is to exchange oxygen in the air for carbon dioxide in the blood.
The bronchioles are the organs of the respiratory system located inside the lungs.
If a patient has low blood oxygen levels but their blood is circulating properly, the most likely organ that is functioning improperly is the alveoli. The alveoli are responsible for exchanging oxygen in the air for carbon dioxide in the blood. If the alveoli are not working properly, this exchange may be compromised, resulting in low blood oxygen levels.
The function of the vena cava is to carry deoxygenated blood from the body to the heart.
