Aids in intestinal absorption of ca+ and phos ______vitamin d_______________________ Identify major differences between water and fat-soluble vitamins with regard to absorption, transport in the body, storage, excretion, toxicity, and frequency of requirement. Water-soluble vitamins are absorbed directly into the blood; whereas fat-soluble vitamins are first absorbed into lymph and then the blood. Water-soluble vitamins are not transported and travel freely. Water-soluble vitamins circulate freely in water-filled parts of the body for storage. Fat-soluble vitamins are stored in the cells associated with fat. Water-soluble vitamins are excreted by the kidneys; which detect and remove excess in urine. Fat-soluble vitamins are less readily excreted; they tend to remain in fat-storage sites. It is possible to reach toxic levels of water-soluble vitamins when they are consumed from supplements.
