Bile is produced in the liver and stored and concentrated in the gallbladder, then transported to the duodenum via the bile duct when needed.

The bile salts break down fats (called gall) via emulsification, which enlarges the surface area of the fats, and allows for more efficient digestion of lipids by enzymes in the duodenum.

Bile is a sticky semi-thick substance that is dark in color. It is a bitter, alkaline, brown/yellow/green fluid. It is an alkaline liuid composed mostly of water, bile salts, bile pigments (bilirubin, from the breakdown of hemoglobin), fats, and cholesterol.
Presuming that we are referencing a HEALTHY HUMAN BEING (post infancy) then: BILE is PRODUCED & SECRETED by the LIVER and EXCESS amounts will be STORED in the GALL BLADDER the liver The liver. It's then stored by the gallbladder. stomach
Bile is made by the liver and stored and released into the intestine in response to dietary fat by the gall bladder.

Bile, a yellow-green bitter fluid that is produced by liver cells, is continuously produced and then stored in the gallbladder until needed. It is a digestive liquid which emulsifies fats and neutralizes acids in partly digested food to aid in digestion. When the stomach senses the presence of fat it secretes a hormone called cholecystokinin which signals the gall bladder to contract and release the bile into the first part of the small intestine where it mixes with the food as it leaves the stomach.

The gallbladder (or cholecyst, sometimes gall bladder) is a small non-vital organ which aids in the digestive process and concentrates bile produced in the liver. The gallbladder stores and releases bile which is made by the liver. The gallbladder releases bile when food containing fat enters the digestive tract. The bile emulsifies fat in food that has been partially digested.

The gallbladder is the sac-like structure under the liver that stores about 30-50 ml of bile. The liver produces bile, and the gallbladder stores it. From there it is excreted, travels down the bile duct, where it passes through the pancreas, which produces lipase (which does break down fat), before it goes into your small intestine. The gallbladder releases bile into the duodenum, part of the small intestine, to aid in the digestion of fats. Bile emulsifies the fats, or breaks them into smaller particles, to assist in their digestion. If the bile salts crystallize, you get gallstones.

The gallbladder will release bile only under the influence of cholecystokinin. When the chyme (food leaving the stomach after processing) passes through the plyoric sphincter (valve muscle connecting the doudenum to the pylorus (bottom part of stomach), this hormone is released, and the bile is released into the doudenum through a series of ducts that also lead from the pancreas, so the enzymes for further digestion can enter as well.

Although the gallbladder does not make the bile, it is where the bile is stored.
The gallbladder stores bile in the body until it is needed in the digestive process. When spicy or fatty foods are eaten, the gallbladder will release the bile into the stomach to help with the digestion.

The combining form is cholecyst-; A gallstone is medically termed cholelithiasis. The removal of a gallbladder is cholecystectmy. And from there procedural or condition terms append the prefix.

A disease of the gallbladder is termed cholecystitis, while the removal of a gallbladder is known as a cholecystectomy. Conversely, the urinary bladder has a prefix cyst-, so a disease of the urinary bladder: cystitis; removal of the urinary bladder: cystectomy, a common method of examining the bladder is by cystoscopy, and a bladder stone is cystolithiasis. The prefix medical term for BILE is bili- because the correct medical term for bile is bilirubin.

Because we use commodes for both urine and feces, seeing this waxy film can be confusing. If a person has a gallbladder problem, there will be more fats in the waste. Physicians often refer to gallbladder disease as the "3F" because GB disease affects "female, fat and 40" (that comment isn't meant as offensive, but "3F" is a simple way to remember facts.) GB affects more women than men; more often in age 40 or over; and in women who are overweight. The person may have upper right belly pain after eating fatty foods. The pain can go "straight through" the body to about bra level at the bottom of the right scapula. If this description fits someone in your home, have them talk to the doctor. A simple ultrasound can confirm GB disease. A medication can help add bile salts when taken with meals. Unless pain is very severe, surgeons usually won't do surgery until it's really bad.

For the toilet, most of it should flush away. If you still see a film, use some gritty cleaner, like Comet. Just don't use other products together or you can cause deadly fumes. Make sure the person who has GB disease understands they should flush immediately after using the toilet. They can even sprinkle Comet along the bowl at the water level so less of the fat clings to the bowl.
