Major Arteries of the Systemic Circulatory System(Starting with Aorta - Upper Body)
Aorta
Ascending Aorta >right and left coronary arteries
Aortic Arch (3 Branches):
1. Brachiocephalic trunk > R. common carotid > R. Subclavian
2. L. common carotid > L. external carotid > L. internal carotid
3. L. Subclavian > L. vertebral L. axillary

Lower Body continued
Descending aorta > visceral and parietal branches (upper chest above diaphragm) >
Abdominal aorta (below diaphragm) > visceral and parietal branches above diaphragm (stomach & lower abdominal areas) >
R. Iliac & L. Iliac > Femoral arteries > to lower limbs

Head and Neck Arteries
These main arteries supply the head & neck: - common carotids - 3 branches from each subclavian artery: a) vertebral arteries b) thyrocervical trunks c) costocervical trunks
