Question

difference between the external respiration and the internal respiration.​

Answer 1

Answer:

External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

Answer 2

Answer:

External respiration:

This is a mechanical process that involves inhaling ( breathing in ) air rich in oxygen into the lungs and exhaling ( breathing out ) air rich in carbon dioxide from the lungs to the air.

Internal respiration:

It is a biochemical process that involves the oxidation of glucose to release energy, with the formation of carbon dioxide and water as by-products.
