Bile salts break up the fat globule into smaller fat droplets. This role of bile salts is best described as
lipid absorption
lipid emulsification
lipid ingestion
lipid digestion
The Correct Answer is B
A. Lipid absorption: Absorption occurs in the small intestine after fats have been digested into smaller molecules. Bile salts do not absorb lipids directly.
B. Lipid emulsification: Bile salts break large fat globules into smaller droplets in a process called emulsification, which increases the surface area for digestive enzymes like lipase to act.
C. Lipid ingestion: Ingestion refers to eating, not the chemical processing of fats.
D. Lipid digestion: Digestion is primarily performed by lipase, not bile salts. Bile salts prepare fats for digestion.

Correct Answer is C
Explanation
A. Urine output will decrease: Vasodilation of efferent arterioles lowers glomerular pressure, leading to a lower GFR and reduced urine output.
B. Glomerular filtration rate will decrease: A wider efferent arteriole reduces resistance, decreasing the pressure inside the glomerulus, hence lowering GFR.
C. Systemic blood pressure will decrease: Local vasodilation of the efferent arteriole does not significantly affect systemic blood pressure. Systemic pressure is influenced more by cardiac output and total peripheral resistance, not glomerular arteriole tone.
D. Net filtration pressure will decrease: Lower glomerular capillary pressure results in reduced net filtration pressure (NFP).
Correct Answer is D
Explanation
A. Store fat-soluble vitamins: Hepatocytes store vitamins A, D, E, and K.
B. Detoxify toxic chemicals: Hepatocytes metabolize and detoxify substances like drugs and alcohol.
C. Process nutrients: They metabolize carbohydrates, lipids, and proteins, modifying absorbed nutrients.
D. Produce digestive enzymes: Hepatocytes do not produce digestive enzymes; that is the role of the pancreas and other gastrointestinal organs.
