Foregut
Three branches of Celiac Trunk
Splenic, Left Gastric, & common hepatic arteries
Muscle that opens & closes to allow bile & pancreatic juice to flow b/t pancreas & small intestine
Hepatopancreatic sphincter (Sphincter of Oddi)
Artery which supplies the hindgut
Inferior Mesenteric Artery
This organ produces bile
Liver
what fetal reminant is ligamentum venosum & what was its function?
ductus venosum & it allowed blood to bypass the liver in the developing fetus
The gastroduodenal artery supplies what two organs?
stomach & duodenum
artery that supplies the transverse colon
Middle Colic Artery
origin of pelvic splanchnic nerves
ventral rami of S2-S4
Contents which go through the porta hepatis
Hepatic portal vein, bile duct (green), & common hepatic artery
what is contained in the blood that goes through the hepatic portal vein into the liver?
Nutrients & Toxins
The superior pancreaticoduodenal arteries anastamose with what artery AND supplies which organs
1. Inferior pancreaticocdueodendal artery
2. pancreas & duodenum
artery which supplies the ascending colon
right colic artery
Describe the innervation above & below the pectinate line
above pectinate line --> superior rectal nerve, visceral innervation
Below pectinate line --> inferior rectal, somatic innervation
2. Secretes catecholamines (epinephrine)
1. Suprarenal cortex
2. Suprarenal Medulla
What two Clincal Applications can occur when blood flow is blocked in the portal system?
Esophageal Varices & Caput Medusa
what artery supplies the gall bladder
cystic artery
The autonomic innervation of the Hindgut (preganglionic, synapse of ganglion, postganglionic)
Preganglionic: lumbar splanchnic nerves
synapse of ganglion: inferior mesenteric ganglion
postganglionic: inferior mesenteric plexus
Diverticulosis is commonly found in this part of the colon
Sigmoid colon
Blood vessels involved in renal vein entrapment syndrome
Bile is stored & secreted in the/from the
Gallbladder
Bacteria associated with Gastric Ulcers
H. pylori
Compare & Contrast the Jejunum & Ileum in terms of:
Wall thickness, Mesentery proper, Vasa recta, Arcades, & Pilcae circulares
Wall thickness:
Jejunum--> Thick & Heavy; Ileum --> Thin & Light
Mesentery Proper:
Jejunum --> less fat; Ileum --> More fat, dense
Vasa Recta
Jejunum --> long; Ileum --> short
Arcades
Jejunum --> few, large loops; Ileum --> Many, short loops
Pilcae Circulares
Jejunum --> closely packed, many; Ileum --> few, absent in distal parts
what two arteries make up the marginal artery
Middle & Left Colic Arteries
What blood vessels make up the porta-systemic Esophageal, Rectal, & Umbilical anastamoses?
Esophageal: Left gastric vein + Esophageal veins
Rectal: Superior rectal veins + Middle/Inferior rectal veins
Umbilical: Paraumbilical veins + Superficial epigastric veins
function of the kidneys
filter blood & secrete waste
