Gas exchange occurs in the lungs. The lungs consist of sacs called alveolus which exchanges oxygen and carbon dioxide to allow for respiration to occur.
Gas exchange in the lungs and in the alveoli is between the alveolar air and the blood in the pulmonary capillaries. This exchange is a result of increased concentration of oxygen, and a decrease of C02. This process of exchange is done through diffusion.as exchange. Homeostasis is maintained by the respiratory system in two ways: gas exchange and regulation of blood pH. Gas exchange is performed by the lungs by eliminating carbon dioxide, a waste product given off by cellular respiration.
