Week 6: Abdominal Vasculature

Question 1

Answer 1

Structure: Inferior vena cava.

Receives blood from:
Lumbar veins.
Right gonadal vein.
Suprarenal veins.
Inferior phrenic veins.
Renal veins.
Hepatic veins.

Distro: Drains into Postero-inferior part of the right atrium.

Question 2

Answer 2

Structure: Sup. Mesenteric Artery

Origin: Abdominal aorta

Distro: Part of GI tract derived from midgut

Question 3

Answer 3

Structure: Inf. mesenteric artery

Origin: abdominal aorta

Distro: supplies part of the GI tract derived from the hindgut

Question 4

Answer 4

Structure: Renal artery

origin: abdominal aorta
distro: kidneys and suprarenal glands

Question 5

Answer 5

Structure: splenic artery

origin: coeliac trunk
distro: spleen, pancreas and stomach

Question 6

Answer 6

Structure: splenic vein

origin: several tributaries that emerge from hilium
distro: unites with sup. mesenteric vein to to form the hepatic portal vein (drains spleen, pancreas, and stomach)

Question 7

Answer 7

Structure: Portal vein

Origin: arises from behind pancreas via the union of the sup. mesenteric and splenic vein

Distro: drains into liver

Question 8

Answer 8

structure: left hepatic vein
origin: within the liver, left hepatic vein runs along the left lobe of the liver

Distro: drains L. lobe of liver into the vena cava

Question 9

Answer 9

structure: right hepatic vein
origin: within the liver, right hepatic vein runs along the right lobe of the liver. Longest and largest hepatic vein.

Distro: drains L. lobe of liver into the inf. vena cava near upper border of caudate lobe

Question 10

Answer 10

Structure: Common iliac vein

Origin: continuation of ext. and int. iliac vein

Left and right common iliac vein unite at the level of L5 to form the inferior vena cava

Distro: drains pelvis and lower limb

Question 11

Answer 11

Structure: Renal veins

origin: hilus of the kidney by interlobar (veins that originate inside) the kidney

Distro: drains kidneys and suprarenals into inf. vena cava

Question 12

Answer 12

structure: abdominal aorta
origin: continuation of the thoracic aorta as it passes through the diaphragmatic aortic aperture
distro: supplies abdomen, pelvis and lower limb via its many branches

Question 13

Answer 13

structure: common iliac artery
origin: terminal branch of the abdominal aorta at L4
distro: supplies pelvis and lower limb

Question 14

Answer 14

structure: common iliac artery
origin: terminal branch of the abdominal aorta at L4
distro: supplies pelvis and lower limb

Question 15

Answer 15

structure: celiac trunk
origin: abdominal aorta below the aortic hiatus of the diaphragm
distro: supplies

Stomach.
Spleen.
Pancreas.
Superior part of the duodenum.
Gallbladder.
Liver.
