, Breathing and Exchange of Gases
We need energy to perform various activities.
This energy is derived from the catabolism of
various components of food, e.g. proteins,
carbohydrates, fats, etc. Oxygen is required for
catabolic processes and carbon dioxide is
released in the process. So the body requires a
continuous exchange of gases, oxygen from the
atmosphere is taken inside and carbon dioxide
produced is taken out. This process of gaseous
exchange is called breathing or respiration.
, All the animals have different organs
specialised for the gaseous exchange.
