A

triangular (Rt/lt) ligament

36
Q

A

triangular rt/lt ligament

37
Q

carries 70-75% of deoxygenated blood TO the liver and has echogenic walls

A

Portal vein

38
Q

carries 25-30% of oxygenated blood TO the liver

A

hepatic artery

39
Q

what kind of flow is toward liver?

A

hepatopedal

40
Q

what is the term for when something courses segments

A

intrasegmental

41
Q

What drains blood FROM the liver and where do they drain into?

A

Hepatic veins and they drain into the IVC

42
Q

what part of the heart does the IVC drain into?

A

right atrium

43
Q

what is are the anterior and inferior landmarks for caudate lobe?

A

anterior: ligamentum venosum; inferior: IVC

44
Q

system that divides liver into 8 segments

A

couinad’s

45
Q

what kind of walls do we see in hepatic veins?

A

anechoic and they have 3 main branches; and travel intersegmental

46
Q

functional liver cells are called

A

hepatocytes

47
Q

hepatocytes can be found in the functional unit of the liver called

A

lobule

48
Q

where does the lobule radiate from

A

it radiates outward from a central vein

49
Q

where do the portal vein and hepatic artery terminate

A

at sinusoids

50
Q

where do bile ducts originate

A

at the bile canaliculi at sinusoids

51
Q

portal triad is found at

A

periphery

52
Q

capillary like spaces

A

sinusoids

53
Q

what are sinusoids lined with

A

Kupffer cells

54
Q

where does phagocytosis take place

A

at sinusoids

55
Q

main function of the liver?

A

detoxification of waste/toxins, metabolizes, digests, stores

56
Q

other liver functions

A

metabolizes carbs, fats, amino acids, and proteins; digestion

57
Q

what does the liver store?

A

glycogen, fat, amino acids, iron, copper, vitamins

58
Q

how does the liver metabolize carbs? why does it do this?

A

glucogenesis and glycogenesis; maintain blood sugar and equilibrium

59
Q

how does the liver metabolize fats? why does it do this?

A

synthesizes triglycerides and cholesterol; produces ketones; it does this to convert fats to more usable forms

60
Q

more usable forms of fat

A

lipoproteins

61
Q

process of metabolizing amino acids in liver? What is the purpose?

A

transamination; to synthesize or alter amino acids to provide the needed ones to build proteins

62
Q

what does transamination require?

A

enzymes such as AST and ALT

63
Q

whats produced when proteins are metabolized in liver?

A

albumin, globulin, clotting factors (with help of vitamin k)

64
Q

what does albumin maintain?

A

fluid homeostasis

65
Q

what does the protein globulin do once metabolized?

A

transports plasma proteins

66
Q

Whats the process and purpose of digestion in liver?

A

production/excretion of bile (hepatocytes); aid in digestion

67
Q

whats produced after detoxification of waste/toxins?

A

urea and uric acid, and waste is excreted into bile

68
Q

process of detoxification and cells used

A

phagocytosis (kupffer cells)

69
Q

an excessive amount of this will cause jaundice

A

bilirubin

70
Q

study last chart.

A
71
Q

where is the liver located?

A

intraperitoneal (inferior to diaphragm)

72

transverse measurement of liver normal

A

21-22.5 cm

73
Q

vertical measurement of liver normal

A

13-17.5 cm

74
Q

AP measurement of liver normal

A

10-12.5cm

75
Q

texture and shape of liver

A

smooth, homogeneous, low level echoes; shape varies

76
Q

thin connective tissue layer covering the liver

A

Glisson’s capsule

77
Q

T/f: fluid collects between the liver and diaphragm

A

false because they are in direct contact

78
Q

T/F: kidney should be hyperechoic to the liver

A

False;
