2.6 Digestive System Intro

Multiple Choice

What is absorption?

• Absorption is the method of filtering out impurities.
• Absorption is the process of taking in or soaking up substances or nutrients.

• Absorption is the process of releasing energy.
• Absorption refers to the act of dividing substances.

Multiple Choice

What is digestion?

• Digestion is the process of breaking down food into absorbable nutrients.
• Digestion is the process of converting food into waste products.
• Digestion is the act of chewing food without breaking it down.
• Digestion is the process of storing food in the stomach.

Multiple Choice

What are the two types of digestion?

• Physical digestion and metabolic digestion
• Nutritional digestion and cellular digestion
• Biological digestion and enzymatic digestion
• Mechanical digestion and chemical digestion

Multiple Choice

What is mechanical digestion?

• Mechanical digestion is the physical breakdown of food into smaller pieces.
• Mechanical digestion is the absorption of nutrients from food.
• Mechanical digestion occurs only in the stomach.
• Mechanical digestion is the chemical breakdown of food.

Multiple Choice

What is chemical digestion?

• Chemical digestion is the process of chewing food into smaller pieces.
• Chemical digestion occurs only in the stomach without any enzymes.
• Chemical digestion is the absorption of nutrients into the bloodstream.
• Chemical digestion is the breakdown of food into smaller molecules by chemical reactions?

• True

• False

Multiple Choice

What is the main role of the esophagus in digestion?

• To transport food from the mouth to the stomach.
• To produce digestive enzymes.
• To absorb nutrients from digested food.
• To break down food into smaller pieces.

Multiple Choice

What is the role of the stomach in digestion?

• The stomach mixes food with acid to break it down for nutrient absorption.

• The stomach filters toxins from the food before it enters the intestines.
• The stomach is primarily responsible for producing bile for fat digestion.

• The small intestine primarily stores food before digestion.
• The small intestine is responsible for breaking down waste products.
• The main job of the small intestine in digestion is to digest food and absorb nutrients.
• The main function of the small intestine is to produce digestive enzymes.

Multiple Choice

What type of digestion occurs in the large intestine?

• No digestion occurs in the large intestines

• Mechanical digestion

• both chemical and mechanical digestion

Multiple Choice

What is the main job of the large intestines in digestion?

• To produce bile for fat digestion.
• To break down proteins into amino acids.
• The main job of the large intestines is to absorb water and and to store waste.
