Final answer:
Vitamins can be either fat-soluble or water-soluble. Fat-soluble vitamins are absorbed with lipids and can accumulate in the body, while water-soluble vitamins are directly absorbed into the bloodstream.
Step-by-step explanation:
Vitamins can be either fat-soluble or water-soluble. Fat-soluble vitamins, such as vitamins A, D, E, and K, are absorbed together with lipids in the intestinal tract and can accumulate in the body's lipid stores. Water-soluble vitamins, like the B complex vitamins and vitamin C, can be directly absorbed into the bloodstream from the intestine. It is important to consume dietary lipids for the absorption of fat-soluble vitamins.
