I NEED HELP ASAP!!!

oxygen that is picked up by the blood after leaving the alveoli is brought where?

Answer 1

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart.

Answer 2

The oxygen is taken to the heart where it's distributed to the entire body
