Liver and pancreas is connected to small intestine.

Final product is absorb into the walls of small intestine.]]> 2016-10-05 11:06:41 UTC https://padlet.com/AFGamerz/chap11/wish/128436064 Large Intestine AFGamerz https://padlet.com/AFGamerz/chap11/wish/128437206 Colon- absorb water and mineral salts

It is not a enzyme
Gall bladder contracts and release bile into the small intestine through bile duct
Function
Break down fats into smaller fat droplets
Process called emulsification

Lipids(fats)--->smaller droplets lipids --->Glycerol and fatty acid
-           bile is used here Lipase is used
- emulsification ouccurs]]> 2016-10-05 11:28:09 UTC https://padlet.com/AFGamerz/chap11/wish/128440044 Enzymes AFGamerz https://padlet.com/AFGamerz/chap11/wish/128444367 Lower than 40`C - Inactive
