Which organ produces the majority of cholesterol in the body?

Explanation:
Cholesterol is produced mainly by the liver. It uses endogenous synthesis (via the HMG-CoA reductase pathway) to make cholesterol that the body needs for cell membranes, steroid hormones, and bile acids. The liver also packages cholesterol into lipoproteins (like VLDL) to transport it through the bloodstream. The brain makes its own cholesterol, but it largely stays in the brain due to the blood-brain barrier and doesn’t significantly contribute to circulating cholesterol. The heart and kidneys do produce smaller amounts, but not the majority. So the liver is the primary source of cholesterol in the body.
