How are the absorbed nutrients transported throughout the body?

Absorbed nutrients are transported throughout the body via the bloodstream and the lymphatic system. Water-soluble nutrients, like amino acids and sugars, enter the bloodstream through capillaries in the villi of the small intestine. They are then carried to the liver via the hepatic portal vein before entering the general circulation. Fat-soluble nutrients, including fatty acids, are absorbed into the lymphatic system through lacteals within the villi. The lymphatic vessels transport these nutrients, forming chylomicrons, which enter the bloodstream at the thoracic duct. This dual transport system ensures the distribution of absorbed nutrients to various tissues and organs for energy production and metabolic functions.
