The cells of the stomach that secrete a protein digesting enzyme are …………………   the parietal cells of the stomach. found in the lumen of the stomach. the enteroendocrine cells of the stomach the chief cells of the stomach.

Describe the regulation of the cephalic, gastric, and intestinal phases of gastric secretion.

Differentiate between the roles of the various cell types of the intestinal mucosa.

How can you differentiate between the serosa and the mucosa under the microscope? b. How is the muscularis of the stomach unlike the muscularis of the other regions of the GI tract? c. What is the main histological difference between the mucosa and the submucosa?

How many major types of cells gastric glands have? Explain.

A.) What major transition in cell types happens from the esophagus into the stomach? B.) How are the major change discussed in question 8 related to the functions of the      esophagus versus the stomach? C) What type of epithelial tissue is the primary type that forms the inner mucosal layer        of the small intestine?

Trace the path of a single protein molecule that has been ingested: The protein molecule will be digested by enzymes made by (a) the mouth, stomach, and colon, (b) the stomach, liver, and small intestine, (c) the small intestine, mouth, and liver, (d) the pancreas, stomach, and small intestine

What would happen if HCl were not secreted in the stomach?

The stomach ...  (A) contains goblet cells that prouce mucus  (B) contains parietal cells to maintainin a high pH (C)contains chief cells that directly secrete pepsin(D) may develop an ulcer sue to H pylori

Trace the path of a single protein molecule that has been ingested: The protein molecule must be digested before it can be transported to and utilized by the cells because (a) protein is only useful directly, (b) protein has a low pH, (c) proteins in the circulating blood produce an adverse osmotic pressure, (d) the protein is too large to be readily absorbed.
