Respiration is the process through which living organisms take in oxygen and release carbon dioxide. It is a vital process for all living organisms as it provides the necessary energy for survival.
Types of Respiration
External Respiration: This involves the exchange of gases between the external environment and the body's cells. In humans, it occurs in the lungs where oxygen is taken in and carbon dioxide is expelled.
Internal Respiration: This is the process of gas exchange that occurs at the cellular level within the body tissues. Oxygen is delivered to the cells, and carbon dioxide is carried away as waste.
Importance of Respiration
Respiration is essential for the survival of all living organisms as it is the process through which energy is produced. This energy is required for carrying out various life processes such as growth, movement, and reproduction.
