Final answer:
After digestion in the small intestine, most dietary fats are absorbed into lacteals, transported by chylomicrons via the lymphatic system, and then to the bloodstream.
Step-by-step explanation:
Immediately after digestion in the small intestine, most dietary fats are absorbed into the lacteals. These are specialized lymphatic vessels that transport absorbed fats and fat-soluble vitamins away from the intestine. Dietary fats are first emulsified by bile salts and lecithin. Then, fatty acids and monoglycerides are absorbed into the cells of the intestinal lining, where they are re-assembled into triglycerides. Once triglycerides are formed, they are packed with other lipids and proteins into particles known as chylomicrons. These chylomicrons are then secreted into the lacteals, which ultimately transport the fats via the lymphatic system to the bloodstream, where they reach the subclavian veins near the heart and are distributed throughout the body.
