What statement does NOT pertain to the cephalic phase of gastric secretion? (It controls the rate at which chyme enters the smal
l intestine., It is triggered by sensory input, such as sight, as well as mental input, such as thinking about food., Mucous cells, chief cells, parietal cells, and G cells receive signals through the submucosal plexus., It usually lasts only a few minutes.)?
It controls the rate at which chyme enters the small intestine
Explanation:
Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.
If the water molecule was linear instead of bent, water
would no longer produce hydrogen bonds. It will lose its polar properties and
nearly all of its properties will change such as boiling point, water tension
and solubility. It would be closer to gas, rather than liquid.
