Lipid Cycle


Lt Col Reynolds
How do the fats in your food make their way into your circulatory system? Let’s check in with Dr. Patel for an explanation.

Dr. Patel
Our bodies begin to process the lipids in our food from the moment that we eat something. Enzymes in our digestive system break down the foods we eat into substances that can be easily absorbed by the small intestine.

Some lipids, like cholesterol, are more of a challenge for the digestive system because they can’t be absorbed in their natural state. Bile salts, which are made in the liver and stored in the gall bladder, help us process these lipids by breaking them into smaller droplets.

An enzyme produced by the pancreas then enables these smaller droplets to cross through the lining of the small intestine. In the intestinal lining, these droplets are assembled into small transport packages called chylomicrons, which carry the lipids through the lymphatic system into the bloodstream.
