Distinguish between ventilation, gas exchange and respirationThis is a featured page



  • Gas exchange is the process of exchanging oxygen and carbon dioxide by diffusion at the alveoli. Gas exchange also occurs when red blood cells give oxygen to cells in exchange for the carbon dioxide produced by cell respiration.

  • Ventilation is the process of bringing fresh air into the body and exhaling stale air.

  • Cell respiration is the process by which mitochondria in cells make ATP energy using glucose or another energy-rich molecule. Cells perform aerobic respiration when oxygen is present; cells perform anaerobic respiration when oxygen is absent.
