human respire through their lungs. In this process we inhale oxygen and give out carbon dioxide.

hey deAr your answer is here
Water and carbon dioxide are bi-products of respiration - they need to be excreted. ... Blood cells circulating through tiny blood vessels near the lungs pick up oxygen and carry it around the body to the sites of respiration. Air is then forced out of the lungs as the diaphragm bows upwards.
