What is the rear vena cava?

Rear vena cava is the main vein that returns blood from the body to the right atrium, where the process of circulation begins another wheel. It is also called Dolní Vena Cava and is one of the two main veins known as Venae Cava. These large veins run vertically down through the back of the center part or torso of the body before branching into every thigh in the lower body and every arm and neck at the upper body. Venae cavae branches have different names because they have different sizes and are located in different parts of the body. Excellent vena cava is a vein that collects blood returned from the head and upper body, and the rear vena Cava gets blood from the lower body.

Any blood vessel that returns blood to the heart is a vein. The rear vena Cava is part of the largest of all veins and sits next to the aorta, the largest of all the arteries in the body. The veins, with the exception of lung veins, carry on the road around the road that represents a cycle of blood circulation.Oxygen poor also carries other waste products such as carbon dioxide and flows from capillaries to small veins known as venule. These vens are gradually mixed into larger veins, until all the blood of the poor in oxygen does not complete the merger and mixing in the superior vena cava or rear vena cava, which are longer and larger than typical blood vessels.

In illustrations showing the anatomy of the main veins and arteries, the back vena cava is almost always shown in blue, as well as other veins. This is because blood in the veins is considered blue because it lacks oxygen. The playgrounds are generally depicted in red to remind the bright red color of oxygen -rich blood. The display of the main blood vessels in this way also helps to solve them in the body when studying illustrations anatomy.

Heart and rear vena cava together with all other blood vessels, regardless of size, form a cardiovascular system. This is also sometimes referred to as a circulatory system. Unlike the arteries that produce a pulse whenIt lies above the bone near the surface of the skin, the veins do not create a pulse.
