Flashcards in production of bile Deck (20):
1
bilirubin is blood
- garbage
- no digestive function
- is not necessary for life
2
cholesterol source of
- steroids
- cholic acid
- chenodeoxycholic acid
3
bile acid vs bile salts
bile acid is lipid soluble
bile salt is water soluble
4
human body is mostly water for fats to enter, fats are covered with bile and its coverings are
- lipid soluble bile acid then conjugated (cover) with sugar
glycine and taurine (bile salts)
- so inside is lipid soluble and outside is water soluble
5
bile salts goes into the
- gallbladder
6
gallbladder concentrates and absorbs
- bile
- absorbs Na, K, Cl, H2O, HCO3 EXCEPTS BILE SALTS
- ALL absorbable substance wil decrease in concentration overtime except bile salts
- will increase concentration answer bile salts except are all absorbable substance
7
CCK
- relaxes the sphincter
- contracts the gallbladder
8
bile
- is indispensable for fat absorption
- from bile salts from cholesterol covered with sugar glycine and taurine for micelles to eat and absorb fats
9
bile salts are recycled in the
- terminal ileum
10
resection of terminal ileum
- no bile salts reabsorption (a conjugated form of bile acid)
- Vit. A, D, E, K and fat malabsorption
- low calcium due to bile salt malabsorption causing osteoporosis
11
case:
after resection of bowel patient suddenly develops osteoporosis what part of the bowel is resected
- terminal ileum (where bile salts are absorb and produce calcium)
12
bilirubin
- gives golden yellow color to bile
13
stercobilin
- gives brown color to the stool
14
40% content of bile are
- phospholipids (lecithin)
15
most prominent feature of small intestine
- are villi
16
water and electrolyte reabsorption greatest at the
- villus tip
17
water and electrolyte secretion greatest at the bottom in the
- crypts of Lieberkuhn
18
only sugar that are absorbed are the
- MONOSACCHARIDES alone
19
greatest site of absorption of water and electrolytes
- COLON
