Abdominal Vasculature

Question 1

how is arterial blood supplied to abdominal viscera

Answer 1

abdominal organs are supplied by branches off abdominal aorta

Question 2

branches of the celiac trunk

Answer 2

common hepatic artery, splenic artery, left gastric

Question 3

celiac trunk

Answer 3

splits into 3 branches that supply the liver, gall bladder, spleen, pancreas, stomach, and duodenum with blood; first large branch of abdominal aorta

Question 4

common hepatic artery

Answer 4

main artery supplying the liver, also sends off a branch to gall bladder and a large branch that passes inferiorly and around the lower boarder of stomach

Question 5

splenic artery

Answer 5

tortous (curvey) artery that passes behind the stomach to spleen; also sends off small branches to the pancreas and a branch to the lateral side of the stomach

Question 6

left gastric

Answer 6

smallest of 3 branches, supply the medial border of the stomach. the left gastric artery and branches from both splenic and common hepatic arteries all form an asatoming network of arteries supplying the stomach

Question 7

superior mesentric artery

Answer 7

large branch off of aorta below the celiac trunk that sends off branches that supply small intestines and part of large intestines (ascending and transverse colon)

Question 8

inferior mesentric artery

Answer 8

supplies test of colon (descending and sigmoid) branches of the superior mesentric artery supply the transverse colon anatomose with branches of the inferior mesentric artery

Question 9

the branches of the aorta supply the digestive tract (celiac and mesentric arteries) drain into veins that form the

Answer 9

hepatic portal vein

Question 10

parts of heptatic portal system

Answer 10

splenic vein, inferior mesentric vein, superior mesentric vein (all draining into hepatic portal veins then to the inferior vena cava)

Question 11

splenic veins

Answer 11

Blood vessel that drain the blood from the spleen, the stomach fundus and part of the pancreas

Question 12

inferior mesentric vein

Answer 12

blood vessel that drains blood from the large intestine; terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein

Question 13

superior mesentric vein

Answer 13

blood vessel that drain the blood from the small intestine’s; terminate behind the neck and pancreas, combined with the splenic vein to form the hepatic portal vein

Question 14

heptatic portal veins

Answer 14

blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas, and spleen to the liver

Question 15

heptatic veins draining into IVC

Answer 15

Drain deoxygenated blood from the liver into the inferior vena cava; 3 upper heptatic veins draining from left, middle, and right parts of liver

Question 16

CLINICAL: Portal Hypertension is

Answer 16

cirrhosis or tumor impedes the blood through the hepatic portal vein; blood has to find alternative route back to the heart parentheses must make it way to superior or inferior vena cava without passing through portal vein-portacaval anastomoses)

Question 17

CLINICAL: Caput Medusae

Answer 17

appearance of distended and enforced superficial epigastric veins, which are seen radiating from the umbilieus across the abdomen; symptom of portal hypertension bc it is caused by dialation of the para umbilical veins, which carries oxygenated blood from mother to fetus

Question 18

CLINICAL: Esophogeal Varices

Answer 18

abnormal, enlarged veins in the tube that connects the throat and stomach (esophagus). This condition occurs most in ppl with serious liver disease and develop when normal blood flow to liver is blocked by a clot or scar tissue

Question 19

CLINICAL: Portal Hypertension

Answer 19

High blood pressure and hepatic portal system, can be fixed by rerouting the blood around the liver to caval system

Question 20

other important branches of arterial blood supply to the abdominal viscera

Answer 20

renal arteries and gonadal arteries

Question 21

renal arteries

Answer 21

arise on the left inferior side of abdominal aorta, supply the kidney with blood, immediately below superior mesentary artery

Question 22

gonadal arteries

Answer 22

refers to testicular in males and ovarian artery in females; “paired” artery with one arising from abdominal aorta
