Digestive System

Which process relies on biological catalysts to accelerate chemical reactions, aiding in the breakdown of food?

The primary function of the large intestine is to secrete enzymes that aid in the digestion of proteins, fats, and carbohydrates.

What is the physiological significance of emulsification in the context of lipid digestion, and which organ facilitates this process by producing bile?

Match each digestive organ with its primary digestive function:

What is the primary role of hydrochloric acid (HCl) in the stomach during digestion?

The presence of villi and microvilli in the large intestine significantly enhances the absorption of nutrients, mirroring their function in the small intestine.

Elaborate on the dual role of the liver in digestion, specifically detailing its exocrine and metabolic functions relevant to nutrient processing.

The process by which food is propelled through the alimentary canal via rhythmic contractions of smooth muscle is known as _______________, which ensures unidirectional movement from the esophagus to the rectum.

Match the enzymes with the substrate they act upon:

Which structural adaptation significantly enhances the absorptive capacity of the small intestine?

The primary function of the esophagus is to enzymatically break down food boluses into chyme through peristaltic contractions.

Describe the role of gut bacteria in synthesizing essential nutrients and their impact on overall host health.

The terminal segment of the large intestine, where feces are stored prior to elimination, is known as the _______________.

Match the digestive secretion with its site of production:

How do enzymes function in digestion?

Mechanical digestion involves the use of enzymes to break down food chemically.

Explain the role of saliva in the initial stages of digestion.

The enzyme found in saliva that begins the digestion of carbohydrates is called _______________.

Match the enzyme with the type of food it digests:

Which organ makes bile to help emulsify fats?

Match the term with its definition:

Which of the following is NOT a function of bacteria in the gut?
