Which of the following is true about bile?Multiple ChoiceCholecystokinin stimulates its production.It contains concentrated enzymes that digest carbohydrates.It is produced by the liver.Secretin stimulates its release into the duodenum.

The statement that is true about bile is: "It is produced by the liver."

Here's why:

1. Cholecystokinin does not stimulate the production of bile. It stimulates the gallbladder to release stored bile into the small intestine, but it does not stimulate the production of bile itself.

2. Bile does not contain concentrated enzymes that digest carbohydrates. Bile aids in the digestion of fats, not carbohydrates.

3. Bile is indeed produced by the liver. This is a continuous process and the bile is either released directly into the small intestine or stored in the gallbladder.

4. Secretin does not stimulate the release of bile into the duodenum. It primarily stimulates the pancreas to release bicarbonate to neutralize stomach acid in the duodenum. It has a minor role in bile release, but it's not its primary function.
