The brachial artery.
The main vessel that supplies oxygenated blood to the upper limb is the subclavian artery. This artery branches off from the aortic arch in the chest and continues into the upper limb where it gives off smaller branches to provide blood supply to the arm and hand.
The largest artery that carries blood to the upper part of the body is the aorta. It originates from the heart's left ventricle and branches into several smaller arteries that supply blood to the head, arms, and upper torso.
The upper rectum receives its blood supply from branches of the inferior mesenteric artery from the abdomen
celiac
The artery located in the upper arm is called the brachial artery. It runs from the shoulder down to the elbow and is a continuation of the axillary artery. The brachial artery is responsible for supplying blood to the upper arm and branches into the radial and ulnar arteries at the elbow.
Brachial artery
The blood flows from the axillary artery into the brachial artery. The brachial artery has a branch called the deep brachial artery. The brachial artery branches into the radial and ulnar arteries. These artiers combine at the wrist forming the superficial palmar arch and the deep palmar arch.
head and upper extremities
After leaving the subclavian artery, blood flows into the axillary artery as it passes under the clavicle and into the armpit region. From the axillary artery, it continues into the brachial artery as it travels down the upper arm. The brachial artery further branches into the radial and ulnar arteries at the elbow, supplying blood to the forearm and hand.
portal artery or phrenic artery or sciatic artery or renal artery
The axillary artery moves oxygenated blood to the the upper limbs, axilla and thorax. :)
The upper parts of extremities consist of @arms @ hands The lower paras of extremities consist of @legs @feet
