NAIL TRAINING – CIRCULATORY SYSTEM
The circulatory system is composed of the cardiovascular system (blood, veins) and the lymphatic system (lymph vessels). Organs and tissues of the body are made up of a network of blood vessels and lymph vessels. Blood, which is flowing in blood vessels, supplies the cells with oxygen and nutrients and carries away carbon dioxide and wastes. The function of the heart allows the circulation of blood in the vascular system.
Blood vessels branch out from the heart then they return there by creating an enclosed circle. Blood circulation is the flowing of blood within this enclosed area.
