Do you know where alveoli are?

im not really sure...

anonymous · Answer

They're tiny air sacks in the lungs. Now... what does blood transport?

anonymous · Answer

blood transports oxygen to the rest of the body ... and cells to fix injuries...

anonymous · Answer

ohhh, do the alveoli give air to the capillaries which send blood to the body, using the oxygen from the alveoli?

anonymous · Answer

Yep. Alveoli are sites of gas exchange. They also take the carbon dioxide out of the blood so it can be breathed out.
