What does the Radial Artery supply blood to?

The radial artery is a major blood vessel in the forearm, and its primary function is to supply blood to the lower arm and hand. It runs along the radial side of the forearm and is one of the two terminal branches of the brachial artery, with the other being the ulnar artery.

By providing oxygenated blood to the structures of the lower arm, including muscles, skin, and bones, the radial artery plays an essential role in the overall circulatory system of the upper limb. This vascular supply is crucial for the proper functioning of the muscles in the forearm, as well as for sensory perception and the overall health of the hand.

In contrast, other vessels are responsible for supplying blood to areas such as the head and neck, the lower leg, and the upper arm, making the radial artery's specific function distinct to the lower arm.
