Intestinal Water and Electrolyte Transport

Abstract

In addition to digestion and absorption of nutrients, the intestinal tract has several essential functions, including a barrier to the outside environment, synthesis of secreted proteins, such as those required for fat absorption and immunoglobulin secretion, and elimination of waste products, as well as transport of salt and water. Failure to efficiently absorbing water and electrolyte, it will lead to dehydration and electrolyte imbalance. Most of these processes are dependent on the specialized mucosal functions and structural requirements discussed in this chapter. Particular emphasis will be placed on aspects of intestinal epithelial biology and the transport of fluid and electrolytes. The discussion of other mucosal functions such as digestion and absorption of nutrients will be covered in subsequent chapters in Part Two of this book.
