this artery arises from the anterior surface of the descending abdominal aorta about 1 cm inferior to the celiac trunk (~L1); unpaired; runs in the mesentery proper
Term
superior mesenteric artery

supplies all of the small intestine (except for the proximal portion of the duodenum), the vermiform appendix, the cecum, the ascending colon, and the transverse colon
Term
1. jejunal and ileal artery
2. ileocolic artery
3. appendicular artery
4. right colic artery
5. middle colic artery

about 15 to 18 of these branches; supply the jejunum and ileum of the small intestine (branch of the superior mesenteric artery)
Term
ileocolic artery
Definition
a branch that runs toward the ileocecal junction; supplies the ileum, cecum, ascending colon, and vermiform appendix (through the APPENDICULAR ARTERY, a branch of the __________ artery)
Term
appendicular artery
Definition
a branch of the ileocolic artery (a branch of the superior mesenteric artery)
Term
right colic artery
Definition
supplies the ascending colon (branch of the superior mesenteric artery)
Term
middle colic artery
Definition
supplies the transverse colon (branch of the superior mesenteric artery)
Term
suprarenal artery
Definition
arise from the descending abdominal aorta; they supply the suprarenal (i.e. adrenal) glands; there can be a number of pairs of these
Term
renal artery
Definition
arises from the lateral aspect of the descending abdominal aorta inferior to the superior mesenteric artery; paired; the left ______ artery supplies the left kidney, while the right ______ artery supplies the right kidney
Term
gonadal arteries
Definition
arises from the abdominal aorta inferior to the renal artery; paired in the male, is called the testicular arteries (in males they will be apart of the spermatic cord to serve the testes); in the female, they are called the ovarian arteries
Term
inferior mesenteric artery
Definition
arises from the anterior surface of the descending abdominal aorta about 3 cm above (~L3) the bifurcation of the aorta; unpaired
Term
inferior mesenteric artery
Definition
supplies the descending colon, the sigmoid colon, and the superior (i.e. proximal) part of the rectum
Term
1. left colic artery
2. sigmoid artery
3. superior rectal artery
Definition
what are the 3 branches of the inferior mesenteric artery?
Term
left colic artery (branch of inferior mesenteric artery)
Definition
supplies the descending colon
Term
sigmoid artery (branch of the inferior mesenteric artery)
Definition
these arteries supply the descending colon and the sigmoid colon of the large intestine
Term
superior rectal artery
Definition
terminal branch of the inferior mesenteric artery; supplies the superior (i.e. proximal) portion of the rectum
Term
internal iliac arteries (branch of the common iliac arteries-where the descending abdominal aorta bifurcated)
Definition
this artery goes into the pelvis and serve the pelvic viscera
Term
celiac trunk, superior mesenteric artery, suprarenal artery, renal artery, gonadal arteries, and the inferior mesenteric artery
Definition
what are the branching arteries off of the descending abdominal aorta from the top to the bottom
Term
celiac trunk, superior mesenteric artery, and the inferior mesenteric artery
Definition
the preganglionic sympathetic fibers will synapse with the postganglionic neurons in what three branches of the descending abdominal aorta?
Term
vagus nerve
Definition
for parasympathetic innervation, this nerve innervates the stomach, small intestine, and proximal 1/2 of the large intestine-everything up to the splenic flexure
Term
sacral parasympathetics
Definition
the preganglionic parasympathetic fibers reach the inferior mesenteric artery as PELVIC SPLANCHIC NERVES and travel along this vessel and its branches to the viscera; they synapse at the walls of the organs with the postganglionic neurons; the transverse colon-vagus (cranial output); descending colon-pelvic splanchinic
Term
inferior vena cava
Definition
begins anterior to the L5 vertebrae by the union of the common iliac veins; lies to the right of the median plane; brings blood back to the right atrium from the body inferior to the diaphragm
Term
1. common iliac vein

4. renal v.

6. inferior phrenic v.
7. hepatic v.
Definition
what are the 7 major tributaries of the inferior vena cava
Term
left renal vein
Definition
where does the left testicular or ovarian v. and the left suprarenal v. drain into?
Term
portal system
Definition
in some parts of the body, blood passes from one capillary bed through a vein into another capillary bed before returning to the heart. this blood circulation is called?
Term
sinusoids
Definition
leaky type of capillary
Term
hepatic portal system
Definition
receives blood from the capillaries of the gastrointestinal organs and spleen and delivers it to the sinusoids of the liver. this allows the liver to store and modify nutrients absorbed from the gastrointestinal tract before they are passed into the general circulation. additionally, the blood draining from the spleen (where most aged and defective RBCs are extracted and broken down) is carrying bilirubin that must be removed from the blood and excreted by hepatocytes
Term
hepatic portal vein
Definition
this vein is formed by the union of the superior mesenteric vein and the splenic vein
Term
inferior mesenteric vein
Definition
what vein drains into the splenic vein?
Term
hepatic portal vein which goes into the liver-->hepatic veins-->inferior vena cava-->heart-->abdominal aorta-->proper hepatic artery-->goes into liver
Definition
what is the pathway for the hepatic portal system?
Term
1) hepatic artery (oxygenated blood)
2) hepatic portal vein (deoxygenated blood with newly absorbed nutrients, drugs, and possible microbes and toxins from the GI tract)
Definition
what are the 2 sources that brings blood to the liver and which one is oxygenated and deoxygenated?
Term
descending abdominal aorta
Definition
pierces the diaphragm at the level of T12 vertebra; lies to the left of the inferior vena cava and on the vertebral bodies throughout its course; ends at the L4 vertebral level, where it bifurcates into the two common iliac artiers
Term
