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.

Neoteny in humans while relinquishing others. For example, the high leg-to-body ratio (long legs) of adult humans as opposed to human infants shows that there is not a holistic trend in humans towards neoteny when compared to the other great apes. Andrew Arthur Abbie agrees, citing the gerontomorphic fleshy human nose and long human legs as contradicting the neoteny hominid evolution hypothesis, although he does believe humans are generally neotenous. Brian K. Hall also cites the long legs of humans as a peramorphic trait, which is in sharp contrast to neoteny. On the balance, an all or nothing approach could be regarded as
