What are the major arteries that supply blood to the arms called?

The major arteries that supply blood to the arms are known as the subclavian arteries. These arteries branch off from the aorta and serve as the main conduit for blood traveling to the upper extremities. Once the subclavian arteries travel beyond the first rib, they become the axillary arteries and then further branch into the brachial arteries, which supply the arm specifically.

The subclavian arteries play a crucial role in ensuring that adequate blood flow reaches not just the arms but also the shoulders, neck, and parts of the head. Understanding this anatomical pathway is important for those studying cardiovascular health, as it relates directly to how blood supply can impact function and mobility in the upper limbs.
