A
- lipid soluble bile acid then conjugated (cover) with sugar

- gallbladder
6

A
- bile
- absorbs Na, K, Cl, H2O, HCO3 EXCEPTS BILE SALTS

A
- 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
