HI!!!! HERE IS YOUR ANSWER:
Oxygen and Carbon- dioxide get exchanged by the process of respiration. Oxygen is taken in through the nasal cavity, from there, it passes through the eosophagus. Within a span of a few seconds, it reaches the lungs from where the air inhaled reaches the small branched sac-like structures called alveolar sacs. In the alveolar sacs, the blood capillaries present within it absorb the oxygen present in the air inhaled. the red blood cell which absorbs the oxygen gives out carbon-dioxide before intake of oxygen. This carbon dioxide is pushed out of the alveolar sacs, into the lungs and out of the nasal cavity by the action of the diaghram. This is how the process of exchange of oxygen and carbon dioxide takes place in the lungs.
