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).
Superficial veins are those whose course is close to the surface of the body, and have no corresponding arteries. Deep veins are deeper in the body and have corresponding arteries. The pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart.
