Gas exchange.
Blood picks up oxygen in the lungs when it passes through the alveoli, tiny air sacs where gas exchange occurs. Oxygen from the air we breathe enters the blood in the lungs and is then carried throughout the body by red blood cells.
Blood is a mixture of dissolved gases (O2 and CO2), plasma (liquid), and cells (red blood cells, white blood cells, and platelets).
