Understanding Digestive System Experiments

Christelle Kanoe from BSN1D demonstrates a digestion experiment using household materials. The experiment simulates the digestive process, starting with the swallowing of food into a ziploc bag representing the stomach. Orange juice and water mimic stomach acid and saliva, respectively, to break down the food. The mixture is then transferred to a stocking, representing the small intestine, where nutrients are absorbed. Finally, the remaining waste is processed through a paper cup with a hole, simulating the large intestine and the act of going to the toilet.

What is the purpose of using orange juice in the experiment?

• To represent the small intestine

• To represent stomach acid

• To represent saliva

• To represent the large intestine

Which material is used to represent the stomach in the experiment?

• A stocking

• A bowl

• A Ziploc bag

• A paper cup

What action is mimicked by squashing the food in the Ziploc bag?

• Stomach digestion

• Chewing

• Swallowing

• Excretion

What is the role of water in the experiment?

• To represent saliva

• To represent stomach acid

• To represent the large intestine

• To represent the small intestine

What does the stocking represent in the experiment?

• The esophagus

• The stomach

• The large intestine

• The small intestine

During the experiment, what happens to the nutrients as the food passes through the stocking?

• They are absorbed into the body

• They are mixed with saliva

• They are turned into waste

• They are stored in the stomach

What is the final step in the experiment that represents the large intestine?

• Adding water to the mixture

• Transferring waste to a paper cup with a hole

• Pouring food into the stocking

• Cutting the Ziploc bag

What does the paper cup with a hole represent in the experiment?

• The stomach

• The small intestine

• The large intestine

• The esophagus

Which material is used to simulate the act of going to the toilet?

• A Ziploc bag

• A paper cup with a hole

• A stocking

• A bowl
