The cross-bar of the "H" is the porta hepatis, or hilus of the
liver, which contains the _______ ducts and the branches of the _______
vein and _______ artery.
left _________ ducts emerge from the liver and unite to form the __________ hepatic duct. This receives the cystic duct from the gallbladder and becomes the _________ bile duct (or choledochal duct; from Gk, chole, "bile"), which opens into the second part of the duodenum in common with or at least beside the pancreatic duc
once the _______ vein and ________ artery blood has traversed the liver lobule via hepatic sinusoids, it is returned to the vena cava by the _______ veins (at least 3: right, middle and left).
A system of vessels in which blood, after passing through one capillary bed, is conveyed through a second set of capillaries before it returns to the systemic circulation. It pertains especially to the _________ __________ system.
a Venous return that goes from one capillary bed to another WITHOUT intervening arteries
The portal venous system (heptic) is responsible for directing blood from parts of the _____________ tract to the ________.
Substances absorbed in the small intestine travel first to the __________
for processing before continuing to the heart. Not all of the gastrointestinal tract is part of this system. The system extends from about the lower portion of the esophagus to the upper part of the anal canal.
It also includes venous drainage from the ______ and ________.
spleen and pancreas
The _______ _________ vein is a vein in the abdominal cavity that drains blood from the gastrointestinal tract and spleen to the liver. It is usually formed by the confluence of the superior mesenteric and _______ veins, and also receives _______ from the inferior mesenteric, gastric, and cystic veins.
- heptic portal
Immediately before reaching the liver, the portal vein divides into
right and left. It ramifies further, forming smaller venous branches
and ultimately portal venules. Each portal venule courses alongside a
hepatic arteriole and the two vessels form the vascular components of
the ________ _______. These vessels ultimately empty into the hepatic sinusoids to supply blood to the liver.
Unlike most veins, the hepatic portal vein does not drain into the heart. Rather, it is part of a portal venous system that delivers venous blood into another _______ system, namely the hepatic __________
of the liver.
In carrying venous blood from the gastrointestinal tract to the liver, the hepatic portal vein accomplishes two tasks; namely,it supplies the liver with metabolic substrates and it ensures that substances ingested are first processed by the liver before reaching the systemic circulation. After draining into the liver ________, blood from the liver is drained by the _________ vein.
right lobe of liver is _________
the right lobe of the liver is larger and consists of __________ (portion), ______ lobe, and _______ lobe
the left lobe of the liver is smaller and and is seperated by the right lobe by the __________ ligament
the liver, the remenant of the _________ __________ vein of an embryo becomes the ligmentum teres of liver
the left umbilical
The bile, stored in the gallbladder, primarily breaks down what type of food materials?
50.Be able to identify the divisions, sphincters, and lining of the stomach. (A&M Figure 2.15 A & B pg 145)
- •Cardiac Region (where esophagus dumps in)
- •Fundus (left dome of diaphragm)
- •Pyloric Region
- •Pyloric Sphincter (regulates food entering duodenum)
- •Lesser & Greater curvatures
Name the mesentery, which attaches from the lesser curvature of the stomach to the hilus of the liver? What three structures run in the free margin of this mesentery? (A&M pg 138-139)
lesser omentum, portal triad
What structure attaches to the greater curvature of the stomach? (A&M pg 138)
