The lymphatic system carries large fats (lipids) and fat-soluble vitamins to the bloodstream. It absorbs these nutrients from the digestive system, particularly through specialized lymphatic vessels in the small intestine called lacteals. Water-soluble nutrients (like proteins and carbohydrates) enter the bloodstream directly through blood capillaries, while fats and fat- soluble vitamins are transported via the lymphatic system as part of a milky fluid called chyle, which eventually drains into the bloodstream through the thoracic duct and subclavian vein.
