Current Question (ID: 14313)

Question:

Breathing is best described as

Options:

1. Utilisation of O₂ by the cells for catabolic reaction.
2. Transport of gases by the blood.
3. The movement of air into and out of the lungs.
4. Diffusion of gases across alveolar membrane

Solution:

Breathing, also known as respiration, refers to the process by which oxygen is taken in by the body and carbon dioxide is eliminated. Breathing involves the movement of air in and out of the lungs through a series of respiratory organs and muscles. The process of breathing is also known as ventilation. Option 1 refers to cellular respiration, which is the process by which cells use oxygen to produce energy. Option 2 refers to the transportation of gases such as oxygen and carbon dioxide in the blood. Option 4 refers to the process by which gases diffuse across the alveolar membrane in the lungs.
