What is Gall Bladder and its functions?
The gallbladder is a small pouch that sits just under the liver. The gallbladder stores bile produced by the liver. After meals, the gallbladder is empty and flat, like a deflated balloon. Before a meal, the gallbladder may be full of bile and about the size of a small pear.
In response to signals, the gallbladder squeezes stored bile into the small intestine through a series of tubes called ducts. Bile helps digest fats, but the gallbladder itself is not essential. Removing the gallbladder in an otherwise healthy individual typically causes no observable problems with health or digestion yet there may be a small risk of diarrhea and fat malabsorption.
Where it is located
Gall bladder is an organ attached under the liver. Two tubes emerged out from liver ( left and right hepatic ducts) forms a common channel ( common hepatic duct) with this common channel a tube from gall bladder joins to form another common channel called common bile duct which eventually opens into the small intestine. Gall bladder is located just below the rib cage.
Gall bladder function
A chemical that liver produce called Bile. Approximately a liver produce 1000 ml to 1500 ml of bile per day. Out of this just 5 percent approximately 75 ml stores in gall bladder. Gall bladder makes the bile consistency thick by absorbing the extra fluid in it. So when food comes out from stomach and reaches to small intestine, a hormone (cholecystokinin) releases and makes the muscles of gall bladder to contract so that thickened bile can flow down to intestine.
So the function of gall bladder is to store just small fraction of bile and makes it thickened.
