Digestive System Functions Quiz

What is the main function of the digestive system?

• Break down food and absorb nutrients

• Produce hormones for growth and development

• Transport oxygen to the body

• Regulate body temperature

Name the organs involved in the digestion of food.

• Brain, heart, liver, kidney, lung

• Skin, bone, muscle, nerve, blood vessel

• Pancreas, spleen, gallbladder, appendix, bladder

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

Explain the process of mechanical digestion.

• The process of mechanical digestion involves the chemical breakdown of food into smaller pieces.

• Mechanical digestion is the absorption of nutrients from the food.

• Mechanical digestion occurs in the small intestine.

• The process of mechanical digestion involves the physical breakdown of food into smaller pieces.

What is the role of enzymes in the digestive system?

• D

• A

• C

• B

How does the digestive system help in the absorption of nutrients?

• By converting food into energy for the body

• By producing enzymes for the breakdown of food

• By transporting nutrients to the stomach

• By breaking down food into smaller molecules that can be absorbed into the bloodstream.

Describe the process of chemical digestion in the digestive system.

• The digestive system only uses mechanical digestion

• Chemical digestion occurs in the lungs

• Enzymes and acids break down food into smaller molecules.

• Food is absorbed directly into the bloodstream

What is the function of the stomach in the digestive system?

• To produce insulin

• To absorb water and nutrients from the food

• To break down food and mix/stores it before moving to the small intestine

• To regulate body temperature

Explain the role of bile in the digestion of fats.

• Bile absorbs fats and stores them in the gallbladder for later use.

• Bile breaks down fats into glucose for energy production.

• Bile transports fats directly to the bloodstream for distribution to the cells.

• Bile emulsifies fats, breaking them down into smaller droplets to increase the surface area for enzymes to work on.

How does the small intestine contribute to the digestive process?

• It further breaks down food particles and absorbs nutrients into the bloodstream.

• It stores excess nutrients for later use.

• It helps in breathing and oxygen exchange.

• It regulates body temperature.

What is the function of the large intestine in the digestive system?

• Producing digestive enzymes

• Breaking down food into nutrients

• Storing bile for later use

• Absorbing water and electrolytes, and storing waste
