|
Produces: BILE (Fat emulsifier)
|
|
|
Fxn. of GALL BLADDER?
|
= Stores & Concentrates BILE SALTS
|
|
|
BILE
|
= ALKALINE;
**Yellow-Green fluid containing: 1) Bile Salts, 2) Pigments, 3)Cholesterol, 4) Phospolipids, **Triglycerides & Phospholipids = emulsifies Fats & aids digestion |
|
|
what IN BILE aids in digestion?
|
1) Bile Salts
2) Phospholipids |
|
|
BILE SALTS do what 2 things?
|
1) emulsify Fats
2) facilitate absorption |
|
|
ENTEROHEPATIC Circulation:
|
= Recycling Mech. for Bile Salts
|
|
|
The ______ _______ is a REMNANT of Fetal UMBILICAL VEIN on Liver
|
= Ligamentum Teres
(ROUND LIGAMENT) |
|
|

|
COMMON HEPATIC DUCT
|
|
|
Where does Bile LEAVE Gall Bladder?
|
CYSTIC DUCT
|
|
|
The Common Hepatic Duct & Cystic Duct FUSe to Form...
|
---->>> BILE DUCT
|
|
|
FXNal units of the LIVER are...
|
= LIVER LOBULES - Plates of Hepatocytes (Liver Cells)

|
from PORTAL TRIADS -------------------into -------> CENTRAL VEIN
|
|
|
KUPFFER CELLS
|
= Hepatic MACROPHAGES that remove: debris, bacteria, & RBCs (From Blood)
|
|
|
The HEPATOCYTES (of Liver) Produce _____ & do what?
|
produce---> BILE - & Store GLUCOSE (as Glycogen & Fat-Soluble Vitamins) & Detoxify body
|
|
|
HEP B= spread by:
|
1) IV,
2) Sex, etc |
|
|
HEP A= spread how?
|
SEWAGE - contamination & Feces - common in restaurants
|
|
|
Role of GALL BLADDER?
|
= STORES Concentrated Bile (from Liver) & Releases when needed through the CYSTIC DUCT
|
|
|
Major Stimulus for GALL BLADDER Contraction is....
|
(CCK) Cholecystokinin - an INTESTINAL HORMONE Released when it's ACIDIC, Fatty CYME= ENTERS the ----> DUODENUM
|
|
|
3 things (CCK) STIMULATES -->
|
1) Gallbladder CONTRACT,
2) SECRETION of Pancreatic Juice, 3) RELAXES ---> HEPATOPANCREATIC SPHINCTER |
|
|
GALL STONES
|
= BILIARY CALCULI - Obstruct flow (of Bile) -- Sharp crystals due to too much CHOLESTEROL or not enough BILE SALTS
