THE CIRCULATORY (CARDIOVASCULAR) SYSTEM

The cardiovascular system is the system of blood circulation. It consists of the heart, the arteries, the veins and capillaries of the human body. The heart is a hollow muscle. It is divided into four chambers. The right heart consists of an upper chamber called an atrium (with the auricle) and a lower chamber called a ventricle. Between these two chambers is a one-way valve, called the tricuspid valve. The left heart has two similar chambers and the mitral valve between them.

Although the heart is a unit, anatomically and functionally, it can be thought of as two isolated pumps - the "right heart" and the "left heart".

The right heart receives blood from the veins and pumps it into the lung by way of the lesser circulatory system. In the lungs the blood is supplied with oxygen. Then it moves into the left heart. From the left heart the well-oxygenated blood is pumped into a large artery called the aorta, which distributes it to the entire body by means of the greater circulatory system. The blood is returned to the heart by means of the veins.
