anatomy
Quick Summary
The ulnar artery is a major blood vessel located in the forearm. It runs parallel to the radius bone, from the elbow down to the wrist. This artery, along with the radial artery, supplies blood to the forearm, hand, and fingers. Arteries, in general, are part of a closed system of tubes that transport blood from the heart to all parts of the body under high pressure. They have strong, elastic walls composed of three layers to ensure efficient blood flow.12
