Q

blood from rt and lt hepatic artery eventually finds its way into spaces aka _ w/in liver tissue

A

sinusoids

24
Q

a portal system is

A

2 capillary beds linked directly (in series) by a blood vessel

25
Q

hepatic portal system

A

the venous system by which nutrient-rich blood passes from the capillary beds of the GI tract to the capillary beds/sinusoids of the liver

26
Q

venous blood supply to the liver via

A

hepatic portal vein (often called the portal vein and to an organ)

27
Q

hepatic portal vein carries blood to the:

A

liver

28
Q

hepatic portal vein collects blood from the: (4 structures)

A

abdominal part of the GI tract, pancreas, spleen, and most of the gallbladder

29
Q

hepatic portal vein is formed by the union of:

A

the spelinc vein and superior mesenteric vein (drain together and form hepatic portal vein; enters at porta hepatis)

30
Q

portal triad contains

A
  1. portal vein
  2. hepatic artery
  3. bile passages
31
Q

portal triad enters liver at

A

porta hepatis

32
Q

blood drainage of liver:

A

the right, intermediate, and left hepatic veins open into the inferior vena cava

33
Q

ducts of the liver:

A
  • rt and lt hepatic ducts
  • common hepatic duct
  • bile duct
34
Q

rt and lt hepatic ducts drain

A

drain bile from rt lobe liver and lt lobe of liver

35
Q

common hepatic duct formed by the union of

A

formed by union of rt and lt hepatic ducts

36
Q

bile duct formed by the union of the _ and _ ducts

A

formed by the union of common hepatic duct and cystic duct from the gallbladder

37
Q

the bile duct unites with the _ to form the _ (the distal end of the ampulla opens into the duodenum)

A

main pancreatic duct to form the hepatopancreatic ampulla (the distal end of the ampulla opens into the duodenum)

38
Q

the circular muscle around the distal end of the bile duct is thickened to form the _

A

sphincter of the bile duct

39
Q

when the sphincter of the bile duct contracts, bile

A

cannot enter the ampulla and thus backs up into the gallbladder (fills the gallbladder once again)

40
Q

the gallbladder is a pear-shaped organ lying btwn _ and _ lobes of liver

A

quadrate and right lobe of liver

41
Q

gallbladder stores and concentrates _

A

bile

42
Q

gallbladder is drained by the _

A

cystic duct

43
Q

the gallbladder, together with the bile ducts inside and outside the liver, form the _

A

biliary system

44
Q

nerves of the liver and biliary system: nerves carrying _ fibers are prominent along the

A

nerves carrying autonomic fibers are prominent along the hepatic artery, portal vein, bile duct, and their branches

45
Q

the stomach is mostly located in

A

mostly located in epigastric and left hypochondriac regions

46
Q

stomach regions (4)

A
  1. cardia
  2. fundus
  3. body
  4. pyloric part
47
Q

cardia of stom

A

surrounds cardial orifice where esophagus enters the stomach

48
Q

fundus of stom

A

superior part that is related to the left dome of diaphragm, limited inferiorly by the horizontal plane of the cardial orifice (cardial notch is btwn esophagus and fundus)

49
Q

body of stom

A

major part of stomach btwn the fundus and pyloric antrum

50
Q

pyloric part of stom is a _-shaped region feeding into the _ (pyloric _ is the wide portion of the pyloric part and _ is the narrow portion of the pyloric part)

A

funnel-shaped region feeding into duodenum (pyloric antrum is the wide portion of the pyloric part; pyloric canal is the narrow portion of the pyloric part)

51
Q

other stomach feats: pyloric orifice

A

inferior opening of the stomach into duodenum, the passage of chyme through which is controlled by the pyloric sphincter

52
Q

other stomach feats: lesser curvature

A

forms the shorter concave border of the stomach

53
Q

other stomach feats: greater curvature

A

forms the longer convex border of the stomach

54
Q

other stomach feats: angular incisure (notch)

A

indicates the junction of the body and pyloric part

55
Q

other stomach feats: gastric rugae (folds)

A

longitudinal internal ridges that allow expansion of stomach
