Solution

Breathing:

  1. Breathing is the action of moving air into and out of the lungs to promote gas exchange with the internal environment, primarily to remove carbon dioxide and bring in oxygen.
  2. The gas exchange permits the organism to absorb oxygen while releasing carbon dioxide.
  3. In mammals, gas exchange occurs through diffusion in the alveoli of the lungs.
