Breathing in other animals

Breathing in Other Animals. Just like human beings, animals also breathe. Breathing is the process of inhaling oxygen and exhaling carbon dioxide. Few organisms have lungs in their chest cavity which helps them to breathe.

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.
