Sample Question 1
What is the function of the epiglottis?

The epiglottis helps in breathing by allowing food and liquid to enter the windpipe and lungs.

The epiglottis is flap of cartilage located in the throat behind the tongue and in front of the larynx. The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing the epiglottis returns to its original upright position.

The epiglottis is part of the digestive system that breaks down food in the stomach.

The epiglottis is a muscle that moves the tongue during speech.

Sample Question 2
What is peristalsis?

Peristalsis is a type of food poisoning.

Peristalsis is a type of genetic disorder.

Peristalsis is a hormone produced by the pancreas.

Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. The process of peristalsis begins in the esophagus when a bolus of food is swallowed. The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where it is churned into a liquid mixture called chyme. Next, peristalsis continues in the small intestine where it mixes and shifts the chyme back and forth, allowing nutrients to be absorbed into the bloodstream through the small intestine walls. Peristalsis concludes in the large intestine where water from the undigested food material is absorbed into the bloodstream. Finally, the remaining waste products are excreted from the body through the rectum and anus.

Sample Question 3
What is digestion?

The process of exhaling carbon dioxide

The process by which food is converted into substances that can be absorbed and assimilated by the body. It is accomplished in the alimentary canal by the mechanical and enzymatic breakdown of foods into simpler chemical compounds.

The movement of blood throughout the body

The conversion of sunlight into usable energy by plants
