Central venous catheter. In medicine, a central venous catheter (CVC), also known as central line, central venous line or central venous access catheter, is a catheter placed into a large vein in the neck (internal jugular vein), chest (subclavian vein or axillary vein) or groin (femoral vein).
Major blood vessels include  the Inferior Vena Cava, Superior Vena Cava, Pulmonary Artery,  Pulmonary Veins, Coronary Artery, and Aorta.    The four parts of the circulatory system are the heart, artery,  capillaries, and the veins. The heart is the center or the main  source of the circulatory system, it pumps blood throughout a  network of blood vessels. An artery is a blood vessel that carries  blood away from the body. Capillaries are very thin vessels that  gases, nutrients, and wastes pass to body cells.
