Question

1. the fluid that surrounds fats to prevent them from clumping up so the body can digest them more easily is:

a. chyme
b. bile
c. saliva
d. gastric acid

1. the gallbladders main function is to:

a. produce bile
b. store and concentrate the bile made by the liver
c. secrete digestive enzymes into the duodenum
d. filter blood

1. what are hardened deposits that form when there is too much cholesterol or too few bile salts to dissolve it,

often blocking the ducts of the gallbladder?
a. diverticula
b. gastric ulcers
c. gallstones (cholelithiasis)
d. kidney stones

1. which organ is responsible for making enzymes that break down macromolecules into their monomers

(carbohydrates into monosaccharides, proteins into amino acids, and lipids into fatty acids) for absorption?
a. liver
b. gallbladder
c. stomach
d. pancreas

1. the exocrine component of the pancreas secretes enzymes, bicarbonate, and water, which together make up

what is released into the small intestine for digestion?
a. gastric acid
b. pancreatic juice
c. bile
d. insulin and glucagon

1. the main site of chemical digestion and nutrient absorption in the digestive system is the:

a. stomach
b. small intestine
c. liver
d. large intestine

Explanation:

• Question 13: Bile emulsifies fats (prevents clumping) for easier digestion.
• Question 14: Gallbladder stores and concentrates liver - made bile.
• Question 15: Gallstones (cholelithiasis) form from cholesterol/bile salt imbalance blocking ducts.
• Question 16: Pancreas makes enzymes for macromolecule breakdown (e.g., carbs to monosaccharides).
• Question 17: Pancreatic juice (enzymes, bicarbonate, water) from exocrine pancreas for small - intestine digestion.
• Question 18: Small intestine is main site for chemical digestion and nutrient absorption.

Answer:

1. B. Bile
2. B. Store and concentrate the bile made by the liver
3. C. Gallstones (Cholelithiasis)
4. D. Pancreas
5. B. Pancreatic juice
6. B. Small Intestine
