Question

“Respiration is a vital function of the body”. Justify this statement.

Answer 1

Respiration is a vital function of the body because it provides the energy required for all life processes. During respiration, food is broken down in the cells with the help of oxygen to release energy. This energy is used for activities such as growth, movement, tissue repair, blood circulation, digestion, and maintaining body temperature. Respiration also removes carbon dioxide, a waste product that can be harmful if accumulated in the body. Since every cell needs a continuous supply of energy to survive and function properly, respiration is essential for life. Therefore, respiration is considered a vital function of the body.
