The basilic vein is a large vein located in the upper limb, primarily responsible for draining blood from the arm and hand. It runs along the inner side of the arm and eventually merges with the brachial veins to form the axillary vein. This vein is important for venous return and is often used in medical procedures, such as blood draws or intravenous access. Anatomically, the basilic vein is accompanied by the basilic vein tributaries, which collect blood from the forearm and hand. It is typically more prominent in individuals with less body fat. Understanding the basilic vein's location and function is crucial for healthcare professionals during various medical interventions.
