After the food goes down the throat, it is met in the gizzard by sand and rocks -these elements help break apart the bones, horns, hooves, hide, and flesh. This more broken-down material then enters the hydrochloric acid of the stomach. The hearts of other reptiles are designed to contain three sections including two atriums and ventricle. The right atrium, which collects the returned de-oxygenated blood and the left atrium which collects the oxygenated blood collected from pulmonary arteries of the lung, takes the blood
Stomach in the maintenance of oro-oesophageal and gastric tissue integrity. The biological effects of salivary EGF include healing of oral and gastroesophageal ulcers, inhibition of gastric acid secretion, stimulation of DNA synthesis, and mucosal protection from intraluminal injurious factors such as gastric acid, bile acids, pepsin, and trypsin and from physical, chemical, and bacterial agents. The human stomach can "taste" sodium glutamate using glutamate receptors and this information is passed to the lateral hypothalamus and limbic system in the brain as a palatability signal through the vagus nerve. The stomach can also sense, independently of tongue and oral taste receptors, glucose,
