Question 1

Angiotensin II

Answer 1

a hormone released in the event of bleeding to initiate vasoconstriction and help maintain blood pressure

Question 2

Aorta

Answer 2

a retroperitoneal, tubular structure coursing inferiorly from the heart, just to the left side of the spine, through the chest and abdomen until it bifurcates into the common iliac arteries. along its course, it give off multiple branches that supply body structures with oxygen-rich blood.

Question 3

celiac artery (CA)

Answer 3

abdominal aorta anterior branch, superior to and within cm of the superior mesenteric artery. also know as the celiac trunk and celiac axis. branches into the left gastric artery, splenic artery, and common hepatic artery

Question 4

common hepatic artery (CHA)

Answer 4

celiac artery branch. courses horizontally to the right and into the gastroduodenal artery(GDA) and proper hepatic artery (PHA)

Question 5

gastroduodenal artery (GDA)

Answer 5

common hepatic artery branch. courses inferiorly, supplies the right side of the greater curvature of the stomach via the right gastoepiploic artery and the pancreatic duodenal area via the superior-anterior and superior-posterior pancreatic duodenal arteries

Question 6

gonadal arteries

Answer 6

abdominal aorta anterior branches inferior to the arteries. course inferiorly. supply their respective organs.

Question 7

inferior mesenteric artery (IMA)

Answer 7

abdominal aorta anterior branch, inferior to the SMA and renal arteries. courses anteroinferiorly dividing into several other smaller arteries supplying the transverse colon, descending colon, and rectum.

Question 8

left gastric artery (LGA)

Answer 8

celiac artery branch. courses superiorly and left lateral. supplies the left side of the lesser curvature of the stomach and eventually anastomoses with the right gastric artery.

Question 9

proper hepatic artery (PHA)

Answer 9

common hepatic artery branch. course right lateral and superiorly. supplies the liver via the right, middle, and left hepatic arteries

Question 10

renal arteries

Answer 10

abdominal aorta bilateral branches located a few cm within the origin of the SMA. course horizontally to each kidney

Question 11

renin

Answer 11

released from the kidneys in the event of bleeding. act on angiotensin II, which initiates vasoconstriction, thus blood pressure is maintained.

Question 12

splenic artery (SPA)

Answer 12

celiac artery branch. courses horizontally to the left with a slight inferior to superior angulation. supplies the spleen, pancreas, and left side of the greater curvature of the stomach.

Question 13

superior mesenteric artery (SMA)

Answer 13

abdominal aorta anterior branch, inferior to and within cm of the celiac artery. courses anteroinferiorly, divides into several arteries that supply the largest portion of the small intestine and the ascending colon part of the transverse colon. the inferior-anterior pancreatic duodenal artery and the inferior-posterior pancreatic duodenal artery originate from the SMA and feed the pancreatic head and duodenal area.

Question 14

Suprarenal arteries

Answer 14

abdominal aorta bilateral branches. also know as the adrenal arteries. course horizontally to each adrenal gland at a level between the CA and SMA
