Gastric acid

Gastric acid production and secretion Gastric acid secretion is said to be a complex process regulated by hormonal and neural pathways (Ceglia et al. 2008). This paper would try to decipher the pathophysiology of gastric acid secretion and explain the changes process in different types of disorders such as gastritis, peptic ulcer disease, and gastroesophageal reflux disease. To begin talking about acid production and secretion, we have first to consider talking about the physiology of the stomach

Disorders Involving Gastric Acid The gastrointestinal tract has barriers and secretions to provide protection from gastric acid. Disruptions in the balance between these protective factors and erosive factors can cause injury to the gastrointestinal tract. Symptoms of these dysfunctions and injuries are similar and may be difficult to diagnose without a thorough knowledge of the disorders. The purpose of this paper is to describe the normal stimulation and production of gastric acid; the changes in

Introduction The stomach naturally produces acid, which is mainly responsible for food digestion and destruction of any foreign pathogen or bacteria ingested with food. Acid is secreted by stimulating the partial cells located in the inner lining of the stomach to release acid in response to a stimulant of food ingested, sight of food, smell, or taste. This acid secretion renders the stomach pH to be very low, this strong acid is an irritant to the stomach. In protection of the stomach, a mucus

is an organ that is part of the digestive system. The stomach is located in the upper left part of the abdominal cavity, below the diaphragm and next to the liver (Stomach, 2013). The inner walls of the stomach contain small pores called gastric pits. The gastric pits contain cells that secrete chemicals that aid in the digestion of food (Nguyen, 2015). In this essay, I will discuss the different cell types of the stomach, how they work together to provide the overall function of the stomach, why

that is used to treat acid reflux which occurs when acid moves back into the esophagus from the stomach. When we swallow food, it goes through the esophagus into the stomach. There is a round muscle at the bottom of the esophagus known as the sphincter that works like a valve. It relaxes when we swallow in order for food to pass through to the stomach. Proton pumps then release acid to help digest the food. The valve is closed tightly by the diaphragm in order to prevent acid from flowing back into

selecting prevention of esophageal acid exposure using proton pump inhibitor (PPI) therapy or modulation of pro-inflammatory mechanisms45. Proton pump inhibitors (PPIs) are used generally in the handling of acid-related disorders. They function by permanently obstructing the hydrogen/potassium adenosine triphosphatase enzyme system (the H+/K+ ATPase, or, more frequently, the gastric proton pump) of the gastric parietal cells. The proton pump is the terminal stage in gastric acid secretion and is directly

This is a possible diagnosis for our patient. The mean age of diagnosis for IBD is 12.5 and our patient fit into that age group. The patient is also of Jewish heritage, which has an increase prevalence of IBD. Furthermore, the patient presents with abdominal pain, low weight, and occult blood in stool that can be found with CD and UC. Our patient does not have a family history of IBD even though 25% of children with IBD do, but that does not rule out the diagnosis. Furthermore, our patient

The dynamic gastric model (DGM) was invented and designed by Dr. Martin Wickham and Dr. Richard Faulks from the United Kingdom. Even though the model is only half the size of the human digestive system, it can be used to investigate the effects of diet, drugs, alcohol and other factors on digestion. The figure is made of plastic and metal and is composed in two parts. The upper section is a funnel and a cylinder shaped container where food, enzyme, and gastric acid are mixed. After the hydration

Sour Burps Are you one of those people who experience sour burps once in a while during the day? This is a symptom of acid reflux, which is a common gastrointestinal condition among people over 40 years old. Sour burping and sour belch are often uncomfortable and embarrassing. Although most people associate these symptoms with gastroesophageal reflux disease, there are many other possible factors that can cause these. Part 1: What Causes Sour Burps? 1. Gastroesophageal Reflux Disease The most

coating, it may dissolve in the small intestines. The gastric juices help to dissolve the medicine because of its high acidic levels. (Howell, 2016) Stomach acid, also known as gastric juices, is mostly made of hydrochloric acid and also consists of water, electrolytes, enzymes, mucus, and intrinsic factor. Gastric acid in the body helps to protect the gastrointestinal tract from harmful bacteria that has been consumed. Since stomach acid is very acidic, it is able to do all of its needs such
