capillaries and the alveoli
Gas exchange takes place in the alveoli of the lungs and in the capillaries. The direct process of gas exchange occurs in alveoli located within the lungs. Blood is sent from the heart through pulmonary arteries, exchanging the carbon dioxide within erythrocytes (red blood cells) for oxygen provided by the air lungs store when inhaling. In the capillaries, oxygen diffuses through the capillary walls into the tissues, and carbon dioxide diffuses from the tissues into the capillaries.
diffusion
Gas exchange happens in the capillaries. Oxygen is replaced with Carbon Dioxide which is transported from the heart.
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
