Functions of the digestive and kidney systems of the body
Functions of the digestive and kidney systems of the body1. 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 flow of gastric juice and from parietal cells begins. This causes secretion of the hormone of gastrin to occur. The release of gastrin causes the release of acid and pepsinogen into the stomach. These chemicals stimulate more stomach mobility. This mobility starts to break up the hot-dog (chyme) in order to give it more surface area so that it can better mix with the acid and pepsinogen. Gastrin also relaxes the pyloric sphincter. Chyme is then passes into the small intestine for main absorption and digestion. The pH in the stomach returns to normal and the stretch receptor stop getting stimulated.
#2 You are having severe stomach cramps, the doctor says that you secretin receptors have been blocked. How has this affected your digestive process and what two hormones might be able to alleviate one of the affects.
Secretion inhibits stomach movement, emptying, slows secretion of gastric juices and causes bicarbonate to be dumped in from the pancreas and liver to the small intestine. This neutralizes the acid that is coming in. Since this process does not occur there is an increase of emptying of chyme into the small intestine. The small intestine fills and gastric juices keep flowing. The acidity will continue to increase (pH falls). The acid is does not get fully neutralized. Two hormones that can elevate the affects are GIP and CCK. These hormones signal the stomach to slow down and decrease stomach emptying. Substances such as fats stimulate the release of GIP and CCK. So if you eat some lard you may help slow stomach movement and slow secretion of gastric juices that are probably causing the discomfort because the acid is being pushed into the small intestine and it does not get neutralized.
Describe the path through which the hot-dog you ate earlier goes once it has made it past the ileocecal valve. (What is your hot-dog called now?) Be sure to include all embarrassing potential side effects of your less than healthily lunch and their causes.
The hard to resemble hot-dog is now called feces after it turn the corner around past the ileocecal value into the large intestine. The large intestine absorbs H20 and salts and Vitamins K and B. K and B vitamins are made from bacteria found in the intestine. If the body feels that the hot-dog you ate earlier may have toxins or microbes that irritate gastro intestinal mucosa you will...
