oxygen exchange

**Oxygen Exchange**

Oxygen exchange refers to the vital biological process where oxygen is transferred between the environment and living organisms. In humans and animals, this occurs primarily in the lungs, where oxygen from inhaled air passes into the bloodstream, while carbon dioxide is expelled. This process is crucial for cellular respiration and energy production. Understanding oxygen exchange is important in fields such as medicine, respiratory therapy, and environmental science.
