Question

what happens to carbon dioxide in the blood that flows through the capillaries in the alveoli ?​

Answer 1

$\huge{\boxed{\rm{\red{Answer!!}}}}$

Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

Answer 2

Answer:

The carbon dioxide in the blood is exchanged for oxygen in the alveoli.

At the same time, carbon dioxide passes out of the capillaries and into the alveoli. When you breathe out, you get rid of this carbon dioxide. The bright red, oxygen-rich blood is returned to the heart and pumped out to the body.
