Question

The process of inhalation and exhalation is called (A) Respiration (B) Breathing (C) Air exchange (D) All of above

Answer 1

Explanation:

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.

Answer 2

Correct Answer will be B) breathing

Explanation:

• Breathing is a physical process where we inhale O2 from environment(inhalation) and release the Co2 into the environment(exhalation)
• Respiration is a biochemical process where glucose is broken down and O2 is consumed in order to produce energy and release Co2 produced from oxidation of complex organic substances.
• Air exchange take place in the alveoli where O2 is diffused from lungs into blood stream down their concentration gradient and Co2 is diffused  from blood into the alveoli along their concentration gradient.
• so option B will be correct
