Equine proximal enteritis the intestinal lumen. Inflammation of the intestine leads to the secretion of a large amounts of electrolytes, primarily sodium and chloride, into its lumen, resulting in the osmotic movement of water. The production of fluid is thought to be due to active hypersecretion, passive secretion of proteins secondary to damage to epithelium of the mucosa and capillaries, and a functional ileus which prevents removal of this fluid. Massive fluid production results in extensive reflux, usually produced at a rate of 50–100 mL/min, in addition to distention of the proximal small intestine, dehydration, and possible shock secondary to hypovolemia.

Composition of the human body not in an essential biological role. The average adult human body contains approximately atoms and contains at least detectable traces of 60 chemical elements. About 29 of these elements are thought to play an active positive role in life and health in humans. The relative amounts of each element vary by individual, mainly due to differences in the proportion of fat, muscle and bone in their body. Persons with more fat will have a higher proportion of carbon and a lower proportion of most other elements (the proportion of hydrogen will be about the same). The numbers in the table
