1

Tiny arteries and veins that supply the walls of blood vessels

vasa vasorum

2

inner layer of the vascular system

tunica intima

3

minute vessels that connect the arterial and venous systems

capillaries

4

communication between two blood vessels without any intervening capillary network

anastomosis

5

outer layer of the vascular system, contains the vasa vasorum

tunica adventitia

6

middle layer of the vascular system; veins have thinner tunica media than arteries

tunica media

7

arises from the posterolateral wall of the aorta, travels posterior to the IVC to suply the kidney

right renal artery

8

arises from the celiac axis to supply the stomach and lower third of the esophagus

left gastric artery

9

supplies the gallbladder via the cystic artery

right hepatic artery

10

vascular structures that carry blood away from the heart

arteries

11

arises from the celiac trunk to supply the liver

common hepatic artery

12

supplies the stomach

right gastric artery

13

branch of the common hepatic artery that supplies the stomach and duodenum

gastroduodenal artery

14

arises inferior to the celiac axis to supply the proximal half of the colon and the small intestine

superior mesenteric artery

15

the abdominal aorta bifurcates at the level of the umbilicus into these, which supply blood to the lower extremities

common iliac arteries

16

arises from the anterior aortic wall at the level of the third or fourth lumbar vertebra to supply the left transverse colon, descending colon, sigmoid colon, and rectum

inferior mesenteric artery

17

arises from the posterolateral wall of the aorta directly into the hilus of the kidney

left renal artery

18

largest arterial structure in the body; arises from the left ventricle to supply blood to the head, upper and lower extremities, and abdominopelvic cavity

aorta

19

small branch supplying the caudate and left lobes of the liver

left hepatic artery

20

arises from the celiac axis to supply the spleen, pancreas, stomach, and greater omentum

splenic artery

21

drains the spleen; travels horizontally across abdomen (posterior to the pancreas) to join the superior mesenteric vein to form the portal vein

splenic vein

22

collapsible vascular structures that carry blood back to the heart

veins

23

formed by the union of the superior mesenteric vein and splenic vein near the porta hepatis of the liver

portal vein

24

drains the left third of the colon and upper colon and joins the splenic vein

inferior mesenteric vein

25

drains the proximal half of the colon and small intestine, travels (anterior to the IVC) to join the splenic vein to form the portal veins

superior mesenteric vein

26

three large veins that drain the liver and empty into the IVC at the level of the diaphragm

hepatic veins

27

leaves the renal hilum, travels anterior to the aorta and posterior to the superior mesenteric artery to enter the lateral wall of the IVC

left renal vein

28

largest venous abdominal vessel that conveys blood from the lbody below the diaphragm to the right atrium of the heart

IVC

29

leaves the renal hilum to enter the later wall of the inferior vena cava

right renal vein

30

disease of the arterial vessels marked by thickening, hardening, and loss of elasticity in the arterial walls

arteriosclerosis
