- The image displays the arterial system of a cat, focusing on the major vessels branching from the aortic arch.
- The arch of aorta is the central vessel from which several major arteries originate to supply blood to the head, neck, and forelimbs.
- The brachiocephalic artery arises first from the aortic arch and quickly divides into the right subclavian artery (supplying the right forelimb) and the right common carotid artery (supplying the right side of the head and neck).
- The left common carotid artery branches directly from the aortic arch, supplying the left side of the head and neck.
- The left subclavian artery also branches directly from the aortic arch, supplying the left forelimb.
- Further downstream, the right subclavian artery gives rise to the right axillary artery, which then continues as the right brachial artery to supply the arm.
