Which one of the following organs breaks fat to produce cholesterol?

The correct answer is Liver

Explanation:

• Cholesterol is a type of lipid that is essential for the body as it helps in the formation of cell membranes, certain hormones, and vitamin D.
• The liver is responsible for producing cholesterol.
• It synthesizes cholesterol from fatty acids and also processes dietary fats.
• The liver also regulates the levels of cholesterol in the bloodstream by converting excess cholesterol into bile acids, which are then excreted.
• When we consume fats, they are broken down in the intestine and then transported to the liver where they are further processed.

Other Options:

• Lungs: The primary function of the lungs is to facilitate the exchange of oxygen and carbon dioxide between the blood and the air we breathe. 
• Intestine: The intestine breaks down fats into fatty acids and glycerol through the action of bile and enzymes. However, it does not produce cholesterol. The broken-down fats are absorbed into the bloodstream and transported to the liver for further processing.
• Kidneys: The primary function of the kidneys is to filter blood and remove waste products and excess substances, including water, to form urine.
