Fish: breath through gill


It is through the breathing process that animals can make gas exchanges with the environment. Through aerobic respiration, animals obtain oxygen and eliminate carbon dioxide in the external environment.


Lung Respiration

It is one that is held by the lungs of animals. This type of breathing occurs in mammals (including humans), birds, reptiles and amphibians (in conjunction with skin breathing).

Mammalian lungs have pulmonary alveoli, which are small pockets composed of blood vessels. These alveoli increase the respiratory surface, making the breathing process very efficient.

Integumentary Breathing

Also called skin breathing, it is breathing that occurs through the skin of the animal. Thus, in this type, gas exchange takes place on the surface of the body. Since the presence of oxygen is greater in the external environment than in the animal's body, this gas enters the body through the skin. When the concentration of carbon gas is higher inside the animal than outside, then it exits through the skin.

Integumentary respiration is characteristic of flattened, coelenterate, poriferous and various annelid species.

Gill Breathing

It is the breath that occurs through the gills. These gills allow the gaseous exchange between the animal's blood and the ambient water (river, sea, lake, etc.) that bathes the gill filaments.

This type of breathing occurs in fish, mollusks and crustaceans.

Tracheal Breathing

It is one that occurs through the tracheas of animals. The trachea is a respiratory organ that has the ability to carry oxygen present in the ambient air to the interior of the animal, where the tissues (in which gas exchange occurs).

Tracheal breathing is typical of insects.
