Question

match each function with the location of its organ, gland, or structure in the digestive system. each answer is used only once. stores and releases bile produces acids and protein - digesting enzymes makes bile secretes saliva secretes digestive enzymes dietary fiber fermentation secretes digestive enzymes and primary site of nutrient absorption oral cavity (mouth) pharynx (throat) salivary glands esophagus liver stomach pancreas gallbladder

Explanation:

• Salivary glands: These glands are located near the oral cavity and their main function is to secrete saliva which contains enzymes (like amylase) that start the digestion of carbohydrates.
• Liver: The liver is a large organ that has multiple functions. One of its key digestive - related functions is to produce bile. Bile helps in the emulsification (breaking down) of fats in the small intestine.
• Gallbladder: The gallbladder is a small, pouch - like organ. It stores the bile produced by the liver and releases it into the small intestine (duodenum) when needed for fat digestion.
• Stomach: The stomach has gastric glands. These glands secrete hydrochloric acid (which kills bacteria and activates pepsinogen to pepsin) and protein - digesting enzymes like pepsin (in its inactive form pepsinogen which is activated by HCl).
• Pancreas: The pancreas is a glandular organ. It secretes a variety of digestive enzymes (such as pancreatic amylase for carbohydrates, trypsin and chymotrypsin for proteins, and lipase for fats) into the small intestine.
• Small intestine (not explicitly labeled but related to the function "secretes digestive enzymes and primary site of nutrient absorption"): The small intestine has intestinal glands that secrete some digestive enzymes. But more importantly, it is the primary site where most of the nutrient absorption (of carbohydrates, proteins, fats, vitamins, and minerals) takes place. The brush - border enzymes on the microvilli of the intestinal epithelial cells also play a role in the final stages of digestion.
• Large intestine (not explicitly labeled but related to "dietary fiber fermentation"): The large intestine has a population of bacteria. These bacteria ferment dietary fiber (which humans cannot digest with their own enzymes) and produce short - chain fatty acids which can be absorbed and used by the body.

Answer:

• Salivary glands: secretes saliva
• Liver: makes bile
• Gallbladder: stores and releases bile
• Stomach: produces acids and protein - digesting enzymes
• Pancreas: secretes digestive enzymes
• Small intestine: secretes digestive enzymes and primary site of nutrient absorption
• Large intestine: dietary fiber fermentation
