Human Digestion and Intestinal Tract Quiz

What is the process of mechanical digestion in the mouth?

• Swallowing whole pieces of food without chewing

• Using a straw to drink liquids instead of swallowing

• Mixing food with water before swallowing

• Chewing and grinding food with the teeth and mixing it with saliva

How does chemical digestion occur in the stomach?

• Gastric juices, primarily hydrochloric acid and pepsin

• Water and fiber

• Bile and lipase

• Saliva and amylase

What is the main function of the small intestine in digestion?

• Absorption of nutrients

• Storage of waste

• Production of bile

• Regulation of blood sugar levels

Explain the role of enzymes in the process of digestion.

• Enzymes help in increasing the size of food particles for absorption

• Enzymes have no role in the process of digestion

• Enzymes help in breaking down food into smaller molecules for absorption

• Enzymes only work in the small intestine and not in the stomach

What type of digestion takes place in the mouth?

• Only mechanical digestion

• Mechanical and chemical digestion

• Only chemical digestion

• No digestion at all

What are the enzymes involved in the digestion of carbohydrates?

• Amylase, sucrase, lactase, and maltase

• Pepsin, trypsin, chymotrypsin, and carboxypeptidase

• Lipase, protease, peptidase, and nuclease

• Glucagon, insulin, adrenaline, and cortisol

How does the small intestine absorb nutrients from food?

• Through the villi in the small intestine

• Through the large intestine

• By releasing enzymes into the stomach

• By absorbing directly through the stomach lining

What are the symptoms of acid reflux disease?

• Blurred vision and dizziness

• Heartburn, regurgitation, difficulty swallowing, chest pain, and chronic cough are some of the common symptoms of acid reflux disease.

• Fever and chills

• Joint pain and swelling

Explain the impact of a high-fiber diet on digestion.

• A high-fiber diet causes indigestion and bloating

• A high-fiber diet slows down digestion and leads to weight gain

• A high-fiber diet can improve digestion by promoting regular bowel movements, preventing constipation, and supporting the growth of beneficial gut bacteria.

• A high-fiber diet has no impact on digestion

What is the role of bile in the process of digestion?

• Bile helps in breaking down proteins

• Bile emulsifies fats to aid in their digestion and absorption

• Bile neutralizes stomach acid

• Bile helps in the absorption of water in the large intestine
