Back

The stomach's main function is to break down food mechanically and chemically, preparing it for further digestion in the small intestine.

Front

Why is the stomach's acidic environment important?

Front

What is the esophagus?

Back

The esophagus is the tube that connects the mouth to the stomach, allowing food to pass through.

Front

What are villi?

Back

Villi are tiny finger-like projections in the small intestine that increase the surface area for absorption.

Front

How do villi aid in digestion?

Back

Villi increase the surface area of the small intestine, allowing for more efficient absorption of nutrients.

Front

What role does the mouth play in digestion?

Back

The mouth is responsible for starting the process of digestion by breaking down food mechanically (chewing) and chemically (saliva).

Front

What is the small intestine's primary function?

Back

The primary function of the small intestine is to absorb nutrients from digested food.

Front

What is the difference between the small intestine and the large intestine?

Back

The small intestine absorbs nutrients, while the large intestine absorbs water and forms waste.

Front

What is the role of digestive enzymes?

Back

Digestive enzymes break down food into smaller molecules that can be absorbed by the body.

Front

What is peristalsis?

Back

Peristalsis is the wave-like muscle contractions that move food through the digestive tract.
