All of the following are examples of physical changes that take place in the mouth during digestion EXCEPT

• when enzymes in saliva break down complex molecules into smaller ones.

• when food particles are broken down by chewing.

• when different complex molecules are brought together by the tongue.

• when saliva moistens food particles.

Which of the following correctly describes how mechanical and chemical digestion in the mouth contribute to nutrient extraction?

• Peristalsis mixes saliva while salts emulsify lipids.

• Mastication increases surface area while amylase breaks down polysaccharides.

• Secretion causes the bolus to become slimy while trypsin breaks down proteins.

• The tongue mixes food with saliva while enzymes increase the size of digested molecules.

A man with indigestion learns from his physician that his digestive system is not adequately breaking down proteins. Which is the best explanation for why this is occuring?

• Pepsin enzymes are not being produced correctly in the stomach.

• Trypsin enzymes are not being produced correctly in the stomach.

• Bile salts are not being released into the intestine by the gall bladder.

• Pancreatic amylase enzymes are not being produced correctly in the pancreas.

Which of the following statements correctly describes why the cells of the small intestine have villi and the cells of the large intestine do not?

• Most absorption of nutrients occurs in the large intestine.

• Most absorption of nutrients occurs in the small intestine.

• The villi assist in breaking down the nutrients in food.

• The villi assist in pushing the food along the digestive tract.

Amylase is an enzyme utilized to digest carbohydrates (starch) in:

• the stomach and large intestine

• the mouth and duodenum (small intestine)

• the small intestine and the stomach

• the mouth and the large intestine

The digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials?

• It goes into the pancreas to await disposal.

• It goes to the right ventricle to await disposal.

• It goes into the large intestine to await disposal.

• It goes into the small intestine to await disposal.

Digestion takes place in a long tube-like canal called the alimentary canal, or the digestive tract. Food travels through these organs in the following order:

• Mouth, esophagus, stomach, small intestine, large intestine and rectum

• Mouth, esophagus, stomach, large intestine, small intestine and rectum

• Mouth, stomach, esophagus, small intestine, large intestine and rectum

• Mouth, stomach, esophagus, large intestine, small intestine, and rectum

Identify the following parts of the digestive system in the following order: 1, 3, 8, 9, 12

• esophagus, stomach, large intestines, small intestines, rectum

• stomach, esophagus, small intestines, large intestines, rectum

• esophagus, stomach, rectum, large intestines, small intestines

• esophagus, stomach, small intestines, large intestines, rectum
