Answer 2

The Essence of Respiration

The essence of respiration lies in the oxidation of organic substances within cells, resulting in the release of energy necessary for vital processes. External respiration refers to the exchange of gases between the atmosphere and the body. Let's examine the options provided and determine the correct description of external respiration.

A. Gas exchange between atmospheric air and blood

This option accurately describes external respiration. During external respiration, oxygen from the atmosphere is taken into the lungs and diffuses into the bloodstream, while carbon dioxide, a waste product, moves from the blood into the lungs to be exhaled. This gas exchange occurs in the alveoli of the lungs, where oxygen is taken up by red blood cells and carbon dioxide is released from them. [[1]]

B. Gas exchange between air and lymph

This option is not an accurate description of external respiration. External respiration primarily occurs in the lungs, where gas exchange takes place between the alveoli and the bloodstream, not the lymphatic system.

C. Consumption of carbon dioxide and release of nitrogen by tissue cells

This option does not accurately describe external respiration. The consumption of carbon dioxide and the release of nitrogen are not the primary functions of external respiration. Carbon dioxide is produced as a waste product during cellular respiration and is eliminated through the process of external respiration.

D. Consumption of oxygen and release of carbon dioxide by tissue cells

This option accurately describes the process of cellular respiration, which occurs within the cells of tissues. During cellular respiration, cells consume oxygen and release carbon dioxide as a waste product. However, this option does not specifically describe external respiration, which refers to the exchange of gases between the atmosphere and the body.

Based on the provided options, the correct description of external respiration is A. Gas exchange between atmospheric air and blood.
