What is the glisson capsule?
capsule around the liver that contains nerves
Does the liver or the glisson capsule cause pain when there is injury?
glisson capsule
What is the ligamentum teres
separates right and left lobes of liver
Blood flow through liver
purpose of spleen
breakdown of RBCs
Functional units of liver:
Lobules
(what do they contain and what does it do)
functional units of liver:
Hepatocytes
produces bile & must have blood flow by them to actually do their job
Are lobules inside hepatocytes or are hepatocytes inside lobules?
hepatocytes are inside lobules
what are sinusoids lined with?
kupffer cells
what are kupffer cells?
type of macrophage in liver that removes old/defective blood cells & gets rid of bacteria/toxins
Flow of duct system in liver:
Secretory functions of the liver
bile production and excretion
bilirubin conjugation
Storage functions of the liver
glucose/glycogen
vitamins A, D, E, K, B1, B2, cobalamin, folic acid
fatty
minerals - iron, copper
amino acids - albumin, beta globulins
vascular functions of the liver
what does unconjugated bilirubin bind to?
albumin
is albumin water soluble?
yes
metabolic functions of the liver
What does the liver synthesize? (proteins)
what is bile production essential for?
fat emulsification and digestion
what does bile contain?
water
cholesterol
bile salts
electrolytes
fatty acids
bilirubin
3 functions of bilirubin metabolism
1 - fat digestion
2 - absorb fats, fat soluble vitamins, minerals
3 - excrete bile pigments, cholesterol, metals, bacteria
flow of bilirubin
RBC –> Hgb –> unconjugated bili –> insoluble so it attaches to albumin –> then the unconjugated bilirubin combines with glucuronic acid to become conjugated bilirubin (soluble)
