Answer 1

Answer:

Itna lamba question ko 5 points diye ho kaun answer dega..............

Answer 2

Answer:

Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide.
