Question

Explain the process of breathing in man.

Answer 1

Breathing in Humans has two processes 

1) Inhalation 

2) Exhalation 

Inhalation: 

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

Exhalation: 

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