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 body is indicated by glabrousness (hairless body). Neoteny of the genitals is marked by the absence of a baculum (penis bone); the presence of a hymen; and the forward-facing vagina. Neoteny in humans is further indicated by the limbs and body posture, with the limbs proportionately short compared to torso length; longer leg than arm length; the structure of the foot; and the upright stance. Humans also retain a plasticity of behavior that is generally found among animals only in the young. The emphasis on learned, rather than inherited, behavior requires the human brain to remain receptive much longer. These
