Organic matter (food) is combined with oxygen and becomes carbon dioxide and water, and this energy is produced. It is therefore essential for the animals take in oxygen. Breathing is responsible for providing oxygen to the cells needed for cellular respiration.

Animals use various techniques to breathe:

Breathing without structures

The simpler animals such as jellyfish and sponges, have respiratory, gases are exchanged across the surface of the body. This occurs mainly in marine animals where the oxygen that is dissolved in water, freely crosses the animal’s body and is passed from cell to cell in your body.

Tracheal breathing

It’s the kind of insect breathing. The tracheae are tubes that open to the outside of the skin through openings called stigmata. Since they penetrate into the oxygen decreasing in diameter, while its walls become thinner. Thus, the oxygen passes through and reaches the cells, while carbon dioxide escapes from them.

Branchlike respiration

It is the general form of breathing in aquatic animals. The gills are organs with very thin walls that were in contact with water, and the interior, with multiple capillaries, which made the exchange, taking the oxygen dissolved in water and yielding carbon dioxide.

Pulmonary respiration

Most land animals breathe through lungs, which are internal cavities found in the respiratory surface. Some spiders have book lungs. This internal cavity whose wall is highly folded, forming thin slices. This also occurs in many insects.
Terrestrial vertebrates have inner cavities are filled with walls of capillaries. These capture oxygen from the air and release carbon dioxide.
