Hdgedog

Biologists say the hedgehog goes into a scientific taxonomy called Hystrix Brachyura is a kind of night animal whose body is covered with thorns. In the classification of living things, Hedgehogs are grouped into chordata phyla. The Chordata phyla consists of subphylum and invertebrate phyla. Where the Hedgehog belongs to a sub-phylum of a vertebrate, an animal that already has a spine or belongs to a class of mammals that is a type of animal that has a mammary gland, like most vertebrates in general. The milk glands (mammary glands) in these animals are still active, but some do not evolve by evolution. However, mammalian glands remain visible when animals undergo the embryonic process stage.

The hedgehog shape can be seen in several organ systems in the body. They are respiratory system, digestive system, transportation system and other reproduction system.

Respiratory system

Unlike most mammals, hedgehogs breathe with the lungs. The air from the trachea passes through the smaller bronchi and bronchioles until it reaches the alveolus. In the alveoli there is an exchange of oxygen gas and carbon dioxide. Nares or porcupine nares in addition to functioning as respiratory organs also have other functions as a means of smell. Very useful for finding food and detecting odors.
