Dietary triglycerides are metabolized primarily by which organ of the body?

Dietary triglycerides are primarily metabolized in the intestine. When food containing fats is consumed, the triglycerides undergo emulsification by bile salts in the small intestine, which allows pancreatic enzymes such as lipase to break them down into free fatty acids and monoglycerides. This process facilitates their absorption through the intestinal mucosa into the lymphatic system and bloodstream.

The other organs mentioned have roles in lipid metabolism, but they do not primarily handle the digestion of dietary triglycerides. The stomach contributes to the initial digestion of food but does not perform significant fat metabolism. The liver plays a crucial role in lipid metabolism and processing fats from the bloodstream but does not directly metabolize dietary triglycerides upon their initial intake. The gallbladder's function is storing bile, which aids in fat emulsification but is not involved in the metabolism of triglycerides itself.
