Question

Respiration is a vital function of the body. Justify.​

Answer 1

Answer:

• The food material taken in during nutrition is used in cells to provide energy for various life processes.
• This energy is released during the process of respiration.
• The oxygen taken in during respiration is transported to cells for carrying out oxidation of food.
• This energy is stored in the form of ATP, which is used for the entire working of the body.
• Also, the CO2 released during respiration has to be removed immediately out of the body.
• So without respiration, the body will not get any energy to function in any way. Hence it is a vital function or process of the body.
