Respiration is a vital process in all living organisms.
Respiratory system is necessary because:
- Respiration is a vital process in all living organisms. Every cell of a plant, an animal or of human body requires energy for various activities. Respiratory system provides this energy by the oxidation of glucose using oxygen.
- Respiratory system helps in breathing through which oxygen from the air is pulled into the lungs and the air containing carbon dioxide is forced out of the lungs.
- Respiratory system helps in gaseous transport. Oxygen of the inhaled air is absorbed by the blood in the lungs where it combines with the haemoglobin present in RBCs. The Oxygen is carried from lungs to the body tissues where the Oxygen is utilised and Carbon dioxide is released.
