The Primary Function of Which Organ is to Deliver Chyme

Question

The primary function of which organ is to deliver chyme to the duodenum at the proper rate?
A) Esophagus
B) Colon
C) Liver
D) Stomach

Accepted Answer

The stomach's primary function is to mix and grind food, creating chyme, which is then delivered to the duodenum at the appropriate rate through the pyloric sphincter. The esophagus delivers food from the mouth to the stomach, the colon absorbs water and electrolytes, and the liver produces bile to aid in digestion but does not directly deliver chyme to the duodenum.
