The vascular system consists of three groups of vessels - arteries, veins and capillaries.
The vessels carrying blood to and from the tissues of the body compose the general circulation. They are called the systemic vessels.
The pulmonary circulation is formed by the vessels carrying blood to and from the lungs.
The portal system is formed by the veins passing to the liver.
Most of the arteries are composed of three coats. The arteries dilate and contract simultaneously with the action of the heart.
