Question

how blood xhanges as ut passes through capillaries in your lungs.​

Answer 1

Answer:

Blood from the heart flows through these capillaries and collects oxygen from 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.
