Functions of the digestive and kidney systems of the body

1. You eat a hot dog, leave the bun, describe the physiological response to the increased food in your stomach. Food inters the stomach and it increases the pH and H+ decreases thus the stomach get more basic. The stomach walls are also stretched. Chemoreceptors and stretch receptors detect the change in pH and the stretch on the walls. Nerve impulses travel to the submucosal plexus this stimulates parasympathetic fiber. Waves of peristalsis occur and the …showed first 75 words of 1805 total…

This causes J-G cells to decrease the release of renin. ADH in turn also decreases but is compensated by the osmoreceptors. Increased sodium in the interstitial fluid also causes the release of ADH, which causes collecting ducts to retain H2O. Arteriolar constriction will occur along with a strong desire to drink water.
