Exploring the Human Digestive System

Gilbert The Grape takes viewers on a journey through the human digestive system, starting from the mouth and ending at the rectum. Along the way, he explains the roles of various organs, such as the esophagus, stomach, small intestine, and large intestine, in breaking down food and absorbing nutrients. The video uses humor and engaging storytelling to teach about digestion, enzymes, and the importance of bacteria in the gut.

What is the primary role of the mouth in digestion?

• Forming stool

• Producing bile

• Breaking down food into smaller pieces

• Absorbing nutrients

How does food move through the esophagus?

• Gravity alone

• Swallowing repeatedly

• Muscle contractions in the stomach

• Peristalsis

What prevents food from re-entering the esophagus from the stomach?

• A valve

• Peristalsis

• Gravity

• Stomach acid

How long is the small intestine?

• About 10 feet

• Over 20 feet

• 8 inches

• 5 to 6 feet

What is the main function of bile in digestion?

• Producing enzymes

• Absorbing water

• Digesting fats

• Breaking down proteins

What role do bacteria play in the large intestine?

• Producing stomach acid

• Breaking down food and nutrients

• Causing infections

• Forming saliva

What is the appendix's primary function?

• Digesting fats

• Housing beneficial bacteria

• Absorbing nutrients

• Producing enzymes

How is stool formed in the large intestine?

• By digesting proteins

• By absorbing water

• By absorbing nutrients

• By producing bile

What triggers the urge to defecate?

• Enzyme release

• Bile production

• Sensors in the rectum

• Stomach contractions

What happens when the external sphincter relaxes?

• Nutrients are absorbed

• Bile is released

• Stool is excreted

• Food is swallowed
