When HDL is present, it reduces which of the following in the blood?

• A. blood sugar levels
• B. blood lipid levels
• C. blood pressure
• D. white blood cell count

Answer: (B)

HDL works by reverse cholesterol transport, pulling cholesterol out of cells and arterial plaques and delivering it to the liver for excretion or reuse. Because it removes cholesterol from the bloodstream, it lowers the amount of lipids circulating in the blood. It doesn’t directly affect blood sugar, blood pressure, or white blood cell count, so those other options aren’t related to HDL’s primary function.
