## Abstract Calcium is absorbed in the mammalian small intestine by two general mechanisms: a transcellular active transport process, located largely in the duodenum and upper jejunum; and a paracellular, passive process that functions throughout the length of the intestine. The transcellular proce
## Abstract Calcium absorption, in terms of mechanisms and function, is well adapted to meet the calcium needs of mammals. When calcium levels in the food are low, the active, mediated transcellular calcium transport assumes primary importance. This process is vitamin Dβdependent, largely localized
