What parts of the body receive blood from the subclavian artery?

Subclavian arteries mainly supply structures of the upper body: the entire upper limb, parts of the chest wall and shoulder region, and even areas of the back. They give off branches like the vertebral arteries that ascend to form the brain’s posterior circulation, so they also contribute to the central nervous system’s blood supply. That combination—arms, chest wall, shoulders, back, and CNS via the vertebrobasilar system—fits the distribution of the subclavian arteries. In contrast, the legs and feet get their blood from arteries branching off the aorta into the abdominal and pelvic regions, not the subclavian. The digestive tract is fed by the celiac trunk and mesenteric arteries, not the subclavian. The face is mainly supplied by the carotid arteries, with only some neck regions receiving blood from subclavian branches, so “face and neck only” isn’t the full picture.
