Chap 18 – Blood
Vessels Continued
Learning Objectives continued
1. 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 Body
1. 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
