Ch 9 Vascular Flashcards
vasa vasorum
Tiny arteries and veins that supply the wall of the blood vessels
tunica media
Middle layer of the vascular system; veins have thinner tunica media than arteries
tunica adventitia
Outer layer of the vascular system; contains the vasa vasorum
tunica intima
Inner layer if the vascular system
anastomosis
Communication between two blood vessels without any intervening capillary network
capillaries
Minute vessels that connect the arterial and venous system
common hepatic artery
Arises from the celiac truck to supply the liver
right renal artery
Arises from the posterolateral wall of the aorta, travels posterior to the inferior vena cava to supply the kidney
superior mesenteric artery
Arises inferior to the celiac axis to supply the proximal half the colon and the small intestine
arteries
Vascular structures that carry blood away from the heart
left hepatic artery
Small branch supplying the caudate and left lobes of the liver
common iliac arteries
The abdominal aorta bifurcates at he level of the umbilicus into these, which supply bold to the lower extremities
gastroduodenal artery
Branch of the common hepatic artery that supplies the stomach and duodenum
aorta
Largest arterial structure in the body; arises from the left ventricle to supply blood to the head, upper, and lower extremities, and abdominopelvic cavity
Inferior mesenteric artery
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
left gastric artery
Arises form the celiac axis to supply the stomach and lower third of the esophagus
splenic artery
Arises from the celiac axis to supply the spleen, pancreas, stomach, and the greater omentum
right hepatic artery
Supplies the gallbladder via the cystic artery
left renal artery
Arises from the posterolateral wall of the aorta directly into the hilus of the kidney
right gastric artery
Supplies the stomach
splenic vein
Drains the spleen; travel horizontally across abdomen (posterior to the pancreas) to join the superior mesenteric vein to form the portal vein
hepatic vein
Three large veins that drain the liver and empty into the inferior vena cava at the level of the diaphragm
portal vein
Formed by the union of the superior mesenteric vein and splenic vein near the porta hepatis of the liver
right renal vein
Leaves the renal hilum to enter the lateral wall of the inferior vena cava
