Chylomicrons are formed in which part of the body?

• A. Liver
• B. Digestive system
• C. Blood plasma
• D. Muscle tissue

Answer: (B)

Chylomicrons are formed right where dietary fats are first absorbed: inside the enterocytes of the small intestine, which is part of the digestive system. After fats are emulsified and broken down, they are reassembled into triglycerides and packaged with cholesterol esters and apolipoproteins within these intestinal cells to create chylomicrons. They’re then secreted into the lymphatic system before entering the bloodstream. This is why the correct choice points to the digestive system. The liver makes other lipoproteins, but chylomicrons originate in the intestinal mucosa, not in liver, blood plasma, or muscle tissue.
