Which of the following best describes the function of bile in the digestive system?
It breaks down proteins into amino acids.
It emulsifies fats to aid in digestion.
It stores glucose for later use.
It produces saliva for mastication.
What is the primary role of peristalsis in the alimentary canal?
To absorb nutrients into the bloodstream
To move food through the digestive tract using muscle contractions
To produce digestive enzymes
To store undigested food
Which structure is described as a pouch at the proximal end of the large intestine?
Rugae
Cecum
Duodenum
Bolus
What is the function of ptyalin in the digestive process?
It breaks down fats into fatty acids.
It converts starches into simple sugars.
It stores glycogen in the liver.
It absorbs water in the large intestine.
Which of the following best defines mastication?
The process of swallowing food
The process of chewing food
The process of digesting proteins

What is the main difference between deciduous teeth and permanent teeth?
Deciduous teeth are used for grinding food, while permanent teeth are not.
Deciduous teeth are temporary and fall out by age 12, while permanent teeth replace them.
Deciduous teeth are only found in adults.
Deciduous teeth are responsible for producing saliva.
Which of the following is a semi-liquid mass of partly digested food expelled by the stomach into the duodenum?
Bolus
Chyme
Bile
Glycogen
What is the primary function of the rugae in the stomach?
To secrete digestive enzymes

Which enzyme is responsible for the breakdown of fats in the digestive system?
Ptyalin
Lipase
Amylase
Pepsin
What is the main function of glycogen in the human body?

Lipase
Ptyalin
Pepsin
Lactase
If the cecum is blocked, which part of the digestive process would be most directly affected?
The movement of chyme from the stomach to the duodenum
The passage of material from the small intestine to the large intestine
The absorption of nutrients in the stomach
The production of bile in the liver
A person’s body is unable to store glucose efficiently. Which substance is most likely not being produced or stored properly?
Bile
