What is the function of the gall bladder in the digestive system?

I think it lets go off a certain chemical that helps break up food?

it is used for store the bile produced frm the liver. ta's all.

It is a reservoir for bile. We really don't need it. Not that much anyway. It's a holdover from the days when we ate lots of fat and needed reserves of bile to digest it. For instance if the tribe brought down a mastodon and everyone gorged on blubber. If you have your gall bladder removed you have to be a little careful. Don't go and eat three triple cheese burgers and wash it down with a milkshake.

produces bile salts to break down and emulsify fats.

The gall bladder stores bile salts. Bile is an enzyme that helps to emulsify fats for the body to metabolize it. The liver makes the bile salts and the gall bladder stores bile between meals. The gall bladder isn't completely necessary because the liver could just be directly connected to the small intestine, specifically the duodenum (by the surgeon of course).

Produces bile salts that break apart fats into smaller compounds.

The gall bladder functions to STORE, CONCENTRATE and SECRETE bile (which is produced in the liver) into the duodenum ( the first part of the small intestines).

Bile functions to emulsify (or help to make soluble) fats. The emulsification process breaks the fat down into smaller droplets and this increases the surface area. An increased surface area means that more lipases (fat digesting enzyme [not found in the bile]) can break down the fat so that it can be easily absorbed and metabolised.

Bile IS not and DOES NOT contain any form of enzyme. Instead, it contains bile salts, bile pigments, phospholipids, cholesterol, and various ions. Also because it is alkaline ... it also functions to neutralise the HCl in the chyme as it moves into the duodenum.

Hope this helps =)
