The most significant information is the presence of Helicobacter pylori infection or the use of NSAIDs. How do the nutrients from food get to the body's cells?
Nutrients from food are absorbed into the bloodstream in the small intestine and transported to the body's cells. Why is “fingerlike” a good description for the villi in the small intestine?
“Fingerlike” describes the villi because they are small, finger-shaped projections that increase the surface area for absorption. What is responsible for the emulsification of lipids in the duodenum?

c) Pancreas What structures are used by both the respiratory and digestive systems?
The pharynx is used by both the respiratory and digestive systems. Which of the following occurs during the gastric phase of gastric secretion?

d) Esophagus Which pancreatic enzyme is responsible for the breakdown of carbohydrates?
Amylase is the pancreatic enzyme responsible for the breakdown of carbohydrates. What structure prevents food and liquids from entering the trachea?
The epiglottis prevents food and liquids from entering the trachea. How does the digestive system support the muscular system?

b) Smelling food What is the cephalic phase?
