How do you explain gaseous exchange?

Answer 1

Gaseous exchange is the process by which oxygen is absorbed from the environment and carbon dioxide is released, primarily occurring in the lungs of mammals. In the alveoli, oxygen diffuses across the thin walls into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. This exchange is driven by differences in partial pressures of the gases, ensuring efficient transport and utilization of oxygen for cellular respiration. Overall, gaseous exchange is crucial for maintaining the body's metabolic functions and homeostasis.
