Where is the central vein?

A central venous catheter is a thin, flexible tube that is inserted into a vein, usually below the right collarbone, and guided (threaded) into a large vein above the right side of the heart called the superior vena cava. It is used to give intravenous fluids, blood transfusions, chemotherapy, and other drugs.

Why is the basilic vein used for venipuncture?

The basilic vein is responsible for taking blood that doesn't have oxygen from the arms back to the heart and lungs, where it's given oxygen again. While you can usually see it clearly, it's considered a last resort in medical procedures.

Which vein is the first choice for venipuncture?

The antecubital area of the arm is usually the first choice for routine venipuncture. This area contains the three vessels primarily used by the phlebotomist to obtain venous blood specimens: the median cubital, the cephalic and the basilic veins.

Where is the brachial vein?
