Upper GI System - Topic Examination

Chyme is the correct answer because it refers to the partially digested food that moves from the stomach to the small intestine. Bile, on the other hand, is a substance produced by the liver and stored in the gallbladder, which helps in the digestion and absorption of fats. Chime, Byme, and Chime are not valid alternatives for digested food.

The pancreas is actually smaller than the stomach. The stomach is a muscular organ located in the upper abdomen, responsible for breaking down food through the secretion of digestive enzymes and acids. On the other hand, the pancreas is a gland located behind the stomach, responsible for producing digestive enzymes and hormones such as insulin. While both organs play important roles in the digestive system, the stomach is larger in size compared to the pancreas.

The cardia is a part of the stomach located at the upper opening where the esophagus connects. Its main function is to allow the passage of food from the esophagus into the stomach. Therefore, it pushes food into the stomach via the esophagus.

The serosa is the correct answer because it is the outermost layer of the upper GI system and forms a clear boundary between the gut and the surrounding tissue. The serosa is a smooth, slippery membrane that helps to protect and lubricate the gastrointestinal organs. It is composed of connective tissue and a layer of simple squamous epithelium called mesothelium.

The common bile duct is located on the bottom left side relative to the stomach.
