Final answer:
Long-chain fatty acids are transported by chylomicrons via the lymphatic system, whereas short-chain fatty acids enter the bloodstream directly.
Step-by-step explanation:
The long-chain fatty acids that are absorbed by the intestinal cells are transported in the lymphatic system rather than the bloodstream directly.
Once the fatty acids cross the intestinal membrane and enter the cells, they are re-formed into triglycerides and packaged into chylomicrons, which are lipid-protein complexes that enable fats and cholesterol to be transported within the aqueous environment of the body's lymphatic and circulatory systems.
The chylomicrons enter the lymphatic system through lacteals found in the intestinal villi and are eventually transported to the circulatory system.
In comparison, short-chain fatty acids, which are more water-soluble, can diffuse directly into the blood capillary of a villus and do not form chylomicrons.
