MICROANATOMY

Detailed explanation-1: -Respiration and breathing are not synonymous.

Detailed explanation-2: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-3: -Answer: No, respiration and breathing are not similar processes. Breathing is a part of respiration in which inhalation and exhalation are carried out. The respiration process, on the other hand, involves the complete oxidation of food molecules to release energy.

Detailed explanation-4: -(i) During inhalation, ribs move inward and the diaphragm is raised. (ii) In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from the blood into the alveolar air.
