Question

Explain the process of breathing in man.

Answer 1

Breathing in Humans has two processes i) Inhalation ii) Exhalation

1. Inhalation - Inhalation is the process of taking oxygen. During this process, ribs come out and the diaphragm moves down. This increases the volume of the lungs and decreases the pressure. This will make the air move towards the lungs.

2. Exhalation: Exhalation is a process of throwing out carbon-dioxide. During this process, ribs go down and the diaphragm moves up. This decreases the volume of the lungs and increases the pressure. As a result, air moves out of the lungs.
