Chap 18 – Blood Vessels Continued
Learning Objectives continued1. Name and give the location of the major arteries and veins in the systemic circulation.
Homework: Finish reading Chap 18. Learn the blood vessels of the body as outlined in this lecture.
Predict The heart is said to be a
“double pump”. What are your thoughts on why it has been given this designation?
2 Main Circulations in the Body1. Pulmonary
(heart to ______)
Functions to
bring blood into close contact with the ______ (air sacs of the lungs) so that gases can be exchanged.
Gas Exchange Between Alveoli and Capillary
Circulation of the Body
2. Systemic (blood to all the rest of the body)
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
Major Arteries – Upper Body
NOTE: Practice Labeling with Mrs. Lanoue on your blank diagram - Roman Numeral I. Arteries of Upper Body
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
