Duodenum

Zollinger-Ellison Syndrome (ZES) is a condition in which one or more tumors form in the pancreas or duodenum. The tumors which are called gastrinomas secrete large amounts of the hormone gastrin. The hormone gastrin causes the stomach to produce too much acid which then leads to peptic ulcers. Zollinger- Ellison Syndrome was first described in 1955 by two gentlemen Zollinger and Ellison. At the time the syndrome consisted of the following triad; gastric acid hypersecretion in the presence of…

disaccharide. As the food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place as the HCl in the stomach stops amylase from continuing to break down the molecules. Carbohydrate are further digested in the SI (duodenum). The chyme from the stomach enters the SI mixes with pancreatic juices also containing amylase, which digests the starch and glycogen into maltose and other…

Esophageal Ulcers which are developed in the esophagus, and lastly, the Duodenal Ulcers which are developed in the first section of the small intestine or known as the Duodenum. All of the following Peptic ulcers are commonly described as a developed sore locating in various positions of the digestive system. The stomach and the Duodenum both have a layer of mucus to protect it from the acids produced by the stomach used to break down foods. A PPU occurs when the inside of the stomach or the…

chime’s acidic pH. Once neutralized, enzyme-rich pancreatic juices (neutral pH) work together with the enzymes of the cells found in the intestinal wall to facilitate digestion of the “three energy nutrients”. Bile (neutral pH) is secreted into the duodenum from the gallbladder (or liver-if someone is without the gallbladder) to emulsify fat for later absorption. 3. Explain the concept of a negative feedback mechanism as it relates to gastric acid secretion. The cycle of this negative…

In some cases I think a medical terminology interpreter would be beneficial. In my own experience I have had doctors that would not even utilize medical terms to make it easier for me to understand, but more often than not specifically in a hospital setting physicians tend to use medical terms and I am left using google to figure out what they explained to me. If a facility were. To offer an. Interpreter, that person should absolutely be regulated and mandated just as doctors and nurses are…

glands, pharynx, the esophagus, the stomach, and duodenum. Each of these structures assists in the digestive functions of the body. The oral cavity is where mechanical digestion begins. Salivary glands secrete saliva to create a bolus. The bolus is then swallowed, moving through the pharynx to the stomach. In the stomach the bolus is mixed with digestive enzymes, acid, and mucin to create chyme. The chyme then moves from the stomach to the duodenum. It then makes its way through the lower…

The enzymes in the stomach break down food as well as kill bacteria. What cells in the stomach function to form enzymes and acids? Parietal cells in the stomach create hydrochloric acid and pepsin which digests proteins. Why doesn’t gastric juice digest the inside of the stomach? The stomach mucosa that lines the stomach is able to resist the juices of the stomach acid. What are sphincters and how are they related to the stomach? The first is the cardiac sphincter located at the top of…

Adult Health III Reflective Journal 5 My goal for this clinical was to understand the interventions that were part of my patient’s plan of care. My patient was in the hospital because of a gunshot wound and he also had acute respiratory distress syndrome from pulmonary edema. My patient had an esophagogastroduodenoscopy (EGD) done in his room. The gastroenterologist was in the patient room with members of the surgery team to place a device called a bear claw. My patient had a small bowel…
