Enlist the salient features that any respiratory organ in animals should process
Answers
Answer:
Introduction
Respiration is an oxidation process which involves degradation of a complex organic compound, hence carbon dioxide and water and energy are produced. Respiration process can be divided into two phases –
External Respiration or Breathing
In this process, animals intake oxygen and release carbon dioxide. It is also known as breathing. This is mainly two phases.
Inspiration: It is the process by means of which oxygen is taken to the lungs.
Expiration: During expiration, carbon dioxide is expelled out from the respiratory organs into the environment.
Internal Respiration or Cellular Respiration
In this process, oxygen is used in chemical reactions within the cells. These reactions release energy from food substances and produced carbon dioxide and water as waste products.

Sugar+O2⟶CO2 +H2O+Energy
Respiration in Animals
The mode of external respiration varies greatly from organism to organism. The basic process of respiration (cellular respiration) is similar in all living organisms. The process of exchange gases varies in different animals.
