Respiration is a biochemical process where organisms break down glucose and oxygen to produce energy, carbon dioxide, and water. This energy is crucial for all cellular activities. Gas exchange, a vital part of respiration, involves the movement of oxygen into the body and the release of carbon dioxide out of it. In humans and many animals, this exchange happens in the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled. In plants, gas exchange occurs through stomata in leaves, facilitating the intake of carbon dioxide for photosynthesis and the release of oxygen. These processes are essential for energy production and maintaining a stable internal environment .
