Describe how carbon dioxide produced by respiring muscle cells reaches the alveolar cavities in mammalian lungs

Describe how carbon dioxide produced by respiring muscle cells reaches the alveolar cavities in mammalian lungs.

Answers

Erick
The carbon (iv) oxide which has been produced by the respiring muscle tissue is diffused into the bloodstream in the form of bicarbonates, a process facilitated by an enzyme called carbonic anhydrase. The carbon (iv) oxide is then carried to the lungs. In the lungs , the Carbon(iv) oxide levels is greater in the blood than in the alveolar air, so the Carbon (iv) oxide diffuses the other way, out of the blood and into the alveoli , from which its exhaled. In the blood, 90% CO2 reacts chemically with water to produce carbonic acid, and it is transported as a bicarbonate ion.
