Final answer:
The duodenum suppresses ghrelin, senses fat content, and releases CCK to stimulate bile release from the gallbladder, helping in fat digestion.
Step-by-step explanation:
The structure that suppresses ghrelin, senses fat content, and releases cholecystokinin (CCK) to stimulate the release of bile, thereby suppressing appetite, is a. Duodenum. The duodenum plays a vital role in the digestive system. It is the first section of the small intestine and is located just after the stomach, separated by the pyloric sphincter. The duodenum is responsible for the majority of chemical digestion.
Bile is necessary for digestion and absorption of dietary fats and is released when fats are detected in the chyme entering the small intestine. Pancreatic juices and bile work together in the duodenum to break down fats into fatty acids and glycerol, which can then be absorbed into the bloodstream.
