1 Cardiovascular System – vessels -Chapter 19C
Arteries – Head & Neck
1. Brachiocephalic trunk – right only – comes
directly off the aortic arch
A. Gives rise to:
. 2. common carotid
. 3. subclavian
.B. Left only - common carotid & subclavian .
come directly off aortic arch

4 C. Both common carotids give rise to:
. 4. Internal carotids
. 5. External carotids
D. Both R & L subclavians give rise to:
. 6. L & R vertebral arteries

13 Arteries of the abdomen
•Visceral organs of the abdominopelvic cavity
•At rest these arteries contain half of all the
blood in the body
•Branch off the Abdominal aorta
13. Celiac trunk – blood to the stomach,
.
liver, pancreas, spleen

16 14. Superior mesenteric – pancreas, all of the
small intestine, most of the large intestine
15. Renal arteries - KIdneys
16. Inferior mesenteric – lower intestine

20 Arteries of the pelvis & legs
17. Common iliacs – bifurcation of distal
abdominal aorta
Common iliacs split to form
. 18. Internal iliacs – pelvic viscera & gluteal
.
Muscles
.
19. External iliacs
External iliacs leave abdominal cavity and
become:
20. femoral arteries, serving the muscles
of the thigh: hamstrings, quadraceps &
adductors
21. Popiteal: creates an anastomosis in the knee
region
Popliteal artery bifurcates and forms two
branches in the lower leg
22. & 23 anterior & posterior tibial arteries

24 Veins –
1. Superior Vena Cava – drains blood from
regions superior to the diaphragm
2. L & R brachiocephalics merge to form the
superior vena cava
Veins draining head and neck
Two veins bring blood from the head to the
brachiocephalics:
3. Internal jugular
4. Vertebral vein
25 5. Subclavian vein merges w/ brachiocephalic
6. External jugular brings blood from head to the
subclavian vein

29 Veins that drain blood from hand, wrist &
lower arm:
7. Radial
8. Ulnar
Ulnar and radial merge and drain blood into:
9. brachial vein which turns into the axillary then
subclavian vein
10. Median cuboidal – the vein Dr. takes blood
from

32 Veins of the abdomen –
•Blood drained from the abdominopelvic region
enters the inferior vena cava
•Veins often follow the paths and share names w/
their arterial counter parts
•Veins draining blood from the digestive tract
(digested food) all empty into a (12) common
hepatic portal vein that goes to the liver to
“process” the blood
13 & 14 Superior and inferior mesenteric veins
empty into the hepatic portal vein

kidneys taking it to the inferior vena cava

38 Veins of the pelvis & lower limb
Great and small saphenous veins drain the calf
& foot
•They are superficial and a common site for
varicose veins
•Used in coronary artery bi-pass surgery
The (16.) anterior tibial and (17) posterior tibial
also drain the calf and foot. They join, at the
knee and form the knee and form the (18.)
popliteal vein. The popliteal continues past the
knee and forms the (19.) femoral vein, which
drains the thigh, and becomes the (20.) external
iliac vein
39The external and (21) internal iliacs join and
form the (22) common iliac which drains into the
inferior vena cava
