Gas exchange is the process by which oxygen is taken in and carbon dioxide is released from the body. In the lungs, oxygen from the air is absorbed into the bloodstream through tiny air sacs called alveoli, while carbon dioxide is removed from the blood and exhaled. This exchange occurs due to differences in the concentration of gases between the air in the lungs and the blood in the capillaries surrounding the alveoli. The oxygen is then transported to cells throughout the body via the bloodstream, where it is used for cellular respiration, while carbon dioxide is carried back to the lungs to be exhaled. **
