Moving through the arteries and the capillaries, the blood product cell activity is saturated and the carbon dioxide is introduced into the vein and through the heart goes into circulation in the second (small) systemic circulation.

The respiratory system of the animal is capable of remarkably function in various environments. It provides the exchange of vital gases, and oxygen delivery to organs and tissues.

Units providing performance of specified functions are: the nose and pharynx, larynx, trachea, bronchi and lungs. The main body is light. It is important to know that the blood that enters the body from the heart, after passing through the first circulation has a dark color, as it contains very little oxygen.
