Question

Gas exchange across the respiratory membrane in metabolizing tissue is called as

• A. Internal respiration
• B. External respiration
• C. Breathing
• D. None of the above

Answer 1

The correct option is A Internal respiration

Internal respiration is also called as tissue respiration. The exchange of oxygen and carbon dioxide between blood and cells in different tissues is called internal respiration. Gas exchange occurs across the respiratory membrane in the peripheral metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

Thus, the correct answer is option A.
