The Dog Heart and Cardiovascular System

The dog cardio system is composed of the dog heart, veins, arteries, conducts and lymphatic glands.

The dog heart, which we can compare to a pump that pushes blood through out the whole body, has a round aspect and is divided into two halves and four cavities which are vertically connected. 

The blood that is low in oxygen and has a high content of carbon dioxide leaves the right ventricle toward the pulmonary artery, where the exchange of gases is made, so that the carbon dioxide is substituted by the oxygen. The blood goes back to the heart through the pulmonary vein toward the left auricle and is the pumped into the left ventricle through the aorta, to all the body parts. After that the blood goes back to the heart through the vena cava.

There is a second circulatory system, the lymphatic, which is responsible for fighting the infections and of returning any fluid to the heart that has been lost through the blood vessels. The spleen is also part of the lymphatic system and acts as a reservoir of red blood cells, while the lymphatic nodules are distributed through out the whole body and are composed of white blood cells. The thymus is another gland that is part of this system.
