Questions and Answers

What is the function of emulsification in the digestive process?

Emulsification helps the fat-digesting enzyme (lipase) work faster and easier on fat globules by breaking them down into smaller globules.

Where is bile juice stored in the digestive system?

Bile juice is stored in the gall bladder.

What are the three main enzymes secreted by the pancreas for digestion?

The three main enzymes secreted by the pancreas are amylase, trypsin, and lipase.

What is the role of villi in the small intestine?

<p>Villi in the small intestine absorb nutrients like sugar and amino acids into the blood, and pass fatty acids into lymph vessels.</p> Signup and view all the answers

How do microvilli contribute to the absorption of nutrients in the small intestine?

<p>Microvilli increase the surface area of the small intestine, enhancing nutrient absorption by further increasing the area for nutrient exchange.</p> Signup and view all the answers

Flashcards

What is emulsification?

Emulsification is the process where fats are broken down into smaller globules, increasing the surface area for lipase to act upon.

Where is bile juice stored?

The gallbladder stores bile juice, which is essential for fat digestion.

What are the main enzymes secreted by the pancreas?

The pancreas secretes three key enzymes for digestion: amylase breaks down carbohydrates, trypsin breaks down proteins, and lipase breaks down fats.

What is the function of villi in the small intestine?

Villi are finger-like projections in the small intestine that absorb nutrients like sugars and amino acids into the bloodstream.

How do microvilli aid in nutrient absorption?

Microvilli are tiny projections on the surface of villi, further increasing the surface area of the small intestine for efficient nutrient absorption.
