Question

Oxygen and CO2 are exchanged between capillaries and alveolus. Do capillaries contain deoxygenated blood while alveolous contains oxygenated blood?

Answer 1

Answer:

this is answer

Explanation:

The aveolus is surrounded by capillaries. So capillaries carry deoxygenated blood to the alveolus where the oxygen from the alveolus diffuses into the blood in the capillaries. The deoxygenated blood is now oxygenated and is carried out of the lung via capillaries that then merge into the pulmonary vein.

In other words, alveolus does not have oxygenated blood it just puts oxygen into the deoxygenated blood hat this brought in.
