Question 3

Match the following phrases with the appropriate process:
-Peristalsis moves food from one organ to the next

Accepted Answer

Propulsion moves food from one organ to the next, and peristalsis is a type of propulsion where waves of muscle contractions push food through the digestive tract. Mechanical breakdown (A) refers to the physical breakdown of food into smaller pieces, such as through chewing or stomach churning. Defecation (C) is the elimination of undigested food and waste products from the body. Ingestion (D) is the intake of food into the mouth. Absorption (E) refers to the process by which nutrients are taken into the bloodstream from the digestive tract. Digestion (F) is the chemical breakdown of food into smaller molecules that can be absorbed.

Question 8

Match the following phrases with the appropriate process:
-Transport of food products from the lumen of the GI tract to the blood or lymph

Accepted Answer

Absorption is the process by which nutrients are transported from the lumen of the GI tract to the blood or lymph.

Question 9

Match the following phrases with the appropriate process:
-Placement of food into the mouth

Accepted Answer

The placement of food into the mouth is called ingestion.

Question 10

Match the following nutrients with their associated digestive enzymes:

Accepted Answer

Lipase is the digestive enzyme responsible for breaking down fats in the small intestine. Pepsin is responsible for breaking down proteins, nuclease breaks down nucleic acids, lactase breaks down lactose (a sugar found in milk), and amylase breaks down carbohydrates.

Question 14

Match the following phrases with the appropriate process:
-Physically fragmenting food particles into smaller particles

Accepted Answer

Physically fragmenting food particles into smaller particles is a process known as mechanical breakdown, which occurs in the mouth during the process of chewing.

Answer: B 
 Propulsion refers to the movement of food through the digestive tract, which involves contractions of smooth muscles in the walls of the digestive organs.

Answer: F 
 Digestion refers to the breakdown of food molecules into smaller molecules that can be absorbed by the body. This process includes both mechanical and chemical breakdown of food.

Answer: D 
 Ingestion refers to the process of taking in food and liquids through the mouth.

Answer: E 
 Absorption refers to the uptake of water, nutrients, and other molecules from the digestive tract into the bloodstream and other tissues of the body.

Answer: C 
 Defection is not a process involved in digestion, but rather refers to the elimination of waste products from the body through the anus.

Question 15

Match the following phrases with the appropriate process:
-Enzymatic reactions that hydrolyze food particles into their building blocks

Accepted Answer

Enzymatic reactions that hydrolyze food particles into their building blocks is the definition of digestion.

Question 20

Match the following nutrients with their associated digestive enzymes:
-Nucleic acids

Accepted Answer

Nucleic acids are broken down by the enzyme nuclease. Pepsin breaks down proteins, lipase breaks down lipids, lactase breaks down lactose (a carbohydrate), and amylase breaks down carbohydrates (specifically starch).
