Stomach

needed to not only prevent bacterial growth, but to create an optimal environment for it’s enzymes to digest the food (now chyme) received through the cardioesophageal sphincter. The small intestine cannot handle such high pH, therefore when the stomach releases chyme into the small intestines, a signal is sent to the pancreas to release an alkaline substance called “sodium bicarbonate” to neutralize the chime’s acidic pH. Once neutralized, enzyme-rich pancreatic juices (neutral pH) work…

water to cover the gills without getting inside the body. Digestion: Digestive track includes mouth, oesophagus, stomach, intestine and anus. It has two stomachs - The cardiac stomach is where the food is stored, where as the pyloric stomach is where most of the digestion occurs. It churns the food for mechanical digestion and uses digestive glands located either side of the stomach, producing digestive enzymes for chemical digestion. The food then passes through the antennal gland, which is…

inhibition of protective prostaglandins" (Huether & McCance, 2012, p. 904). The outcome of these caustic chemical reactions leads to a breakdown of the mucosa and development of ulcers. Gastritis Gastritis is an inflammatory process that affects the stomach (Huether & McCance, 2012). In gastritis, gastric acid stimulation and production are altered. The pathogenic changes result from acute exposure to drugs, chemicals or chronic processes related to degeneration or H. pylori bacteria (Huether…

healthy because it can improve blood flow to the intestine and colon. 5.0 Disease that affect the system Gastroesphageal Reflux Disease (GERD) is a disease which affect the digestive system. Weakness of the valve between the esophagus and stomach may allow stomach acid to reflux into the esophagus and irritate and inflame the lining. 5.1 Symptoms Heartburn is the most common symptom of GERD. It usually feels like a burning chest pain beginning behind the breastbone and moving upward to the…

into feces for defaction. There is an acidic fluid that passes from the stomach through the small intestine, consisting of gastric juices and partly digested food called Chyme. This acidic, Chyme reaches the lower GI tract through the pyloric sphincter of the stomach. Chyme passes through the pyloric sphincter and enters the duodenum. The duodenum is apart of the small intestine and is located inferior to the right of the stomach. Absorptions of nutrients also takes place in the walls of the…

There is a myth that states gum will stay in the human stomach for 7 years after being swallowed. However, studies have shown that this is in fact incorrect. Gum is very digestible and isn’t hard to break apart in the stomach unless consumed in very large quantities due to its sticky texture. In many incidents, swallowed gum passes through the digestive system as well as any other food. When somebody swallows gum the material is first taken down the esophagus (the first mushed food is called…

has two layers. Its interior is lined with cells that are packed very closely together creating a smooth surface. The circular muscle around the outside of the oesophagus is also smooth. Your swallow forces the food toward the stomach. Step 3. Once it reaches your stomach the cheeseburger is broken down even more, the amylase that went to work on the food in your mouth is taken down by acid. Hydrochloric acid is the main component…

Stomach When the chewed food has passed from the mouth the esophagus, it reaches the stomach where enzymes peruse the process of breaking down the food into usable substances and forms. The braking down is achieved through stomach acid which is released from the cell lining of the stomach, along with powerful enzymes which help to further break down the food. 4. Small Intestine The contents from the stomach reach the small intestine once they have been…

proteins that speed up chemical reactions without change to themselves. • Esophageal sphincter – the opening between the esophagus and he stomach that relaxes and opens to allow the bolus to travel into stomach and then closes behind it. Prevents the reflux of gastric contents. • Pyloric sphincter – a circular muscle that forms the opening between the duodenum and the stomach. It regulates the passage of food into the small intestine. 2. Mouth Digestive process starts in the…

Pseudomelanosis gastri and duodeni is a rare endoscopic mucosal finding, characterized by the accumulation of iron in macrophages of the lamina propria of the stomach and duodenum. The clinical significance and long term sequelae have not been clarified. However, this benign condition is associated with a variety of clinical conditions, such as essential hypertension, chronic renal failure, diabetes mellitus, long term intake of iron supplements and furosemide. Pseudomelanosis duodeni appears to…
