- While there are more advantages than disadvantages of a monogastric digestive system, there are still disadvantages that exist.Animals with a monogastric digestive system are unable to extract energy from the cellulose that they consume in their foods.he main parts of the digestive system are the mouth, esophagus, stomach, small intestine, large intestine, liver, gull bladder, and pancreas.

- All the firms in a perfectly competitive market earn economic profit equal to zero. (Since economic profit is the profit after accounting for the implicit cost of a firm, zero economic profit means positive accounting profit.

- Risk Factors. Obesity or acute weight gain: increase intra-abdominal pressure. Gastroparesis: diabetes, pre-diabetes, narcotics use, hypothyroidism, idiopathic. Habitual and volitional excessive gastric distension syndrome. Aerophagia and carbonated beverages: delivery of gastric acid. and enzymes to LP with each burp or belch. Hiatal hernia, alcohol, caffeine, peppermints, and chocolates:

- Caffeine has a number of adverse effects on the gastrointestinal tract. It relaxes the lower oesophageal sphincter and can predispose to gastro-oesophageal reflux disease. It also causes gastric hypersecretion, which is associated with susceptibility to ulceration.

Digestive System: Facts, Function & Diseases Many symptoms can signal problems with the GI tract, including: abdominal pain, blood in the stool, bloating, constipation, diarrhea, heartburn, incontinence, nausea and vomiting and difficulty swallowing, according to the NIH. Among the most widely known diseases of the digestive system is colon cancer.ven the smell of food can generate saliva, which is secreted by the salivary glands in the mouth, contains an enzyme, salivary amylase, which breaks down starch. Teeth, which are part of the skeletal system, play a key role in digestion. In carnivores, teeth are designed for killing and breaking down meat.

Digestive System of the Lower Torso Digestive System of the Lower Torso. The digestive organs of the lower torso include lower gastrointestinal (GI) tract, which consists of the small intestine, large intestine, and anus. Several accessory organs, such as the liver and pancreas, assist the lower GI tract with the digestion of food to release many essential nutrients. By the time this food exits the lower GI tract through the anus, the food has been completely digested and almost all of the nutrients have been absorbed into the bloodstream.

- In the brain, the vagus helps control anxiety and depression. In the gut, it increases stomach acidity, digestive juice secretion, and gut flow. Since the vagus nerve is important for increasing gut flow (motility), having less vagus activation will increase your IBS risk, which is a result of slower flow (R).

- The mucosa of stomach is divided in three layers. The surface epithelium : surface epithelium contains gastric pits and gastric glands. Gastric pits are invagination of epithelium into lamina propria (second layer of mucosa). Gastric glands produce enzymes, HCl (hydrochloric acid) and gastric hormones.

THE DIGESTIVE SYSTEM The small intestine is the major site for digestion and absorption of nutrients. The small intestine is up to 6 meters long and is 2-3 centimeters wide. The upper part, the duodenum, is the most active in digestion.everal specialized compartments occur along this length: mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. Accessory digestive organs are connected to the main system by a series of ducts: salivary glands, parts of the pancreas, and the liver and gall bladder (bilary system).

Chagas disease Benznidazole and nifurtimox cause temporary side effects in up to 40% of people including skin disorders, brain toxicity, and digestive system irritation. It is estimated that 7 to 8 million people, mostly in Mexico, Central America and South America, have Chagas disease as of 2013. In 2006, Chagas was estimated to result in 12,500 deaths per year.

- Powerful hydrochloric acid in the stomach helps break down the bolus into a liquid called chyme. A thick mucus layer that lines the stomach walls prevents the stomach from digesting itself. When mucus is limited, an ulcer (erosion of tissue) may form. Food is digested in the stomach for several hours. During this time, a stomach enzyme called pepsin breaks down most of the protein in the food. Next, the chyme is slowly transported from the pylorus (end portion of the stomach) through a sphincter and into the small intestine where further digestion and nutrient absorption occurs.

- ♦ Can make diabetes worse - when food delayed in the stomach finally enters the small intestine and is absorbed, blood glucose levels rise. Since gastroparesis makes stomach emptying unpredictable, blood glucose levels can be erratic and difficult to control.

What Is Gastroparesis? 1 Bezoars can cause obstructions in the stomach that keep food from passing into the small intestine. 2  People who have both diabetes and gastroparesis may have more difficulty because blood sugar levels rise when food finally leaves the stomach and enters the small intestine, making blood sugar control more of a challenge.

Upper Gi disorders 5 Acid, pepsin, and H. pylori infection play an important role in the development of gastric ulcers. When a break in the mucosal barrier occurs, hydrochloric acid injures the epithelium. Gastric ulcers may then result from back-diffusion of acid or dysfunction of the pyloric sphincter.

Hypothyroidism, Intestinal Bacterial Overgrowth, & Lactose Intolerance “In hypothyroidism, digestion in the stomach and intestines is delayed. The concentration of acid and enzymes involved in digestion may be diminished. Motility of the gut is reduced and food is propelled more slowly along the tract. Absorption through the intestinal wall is slower.” -Broda Barnes, MD, PhD.

CLICK PLAY On Player Below... News Flash: Acid Reflux Caused by Too Little Acid, Not Too Much... The esophagus is normally protected from these acids by a one-way valve mechanism at its junction with the stomach called the lower esophageal sphincter (LES). The LES allows the food chunks (bolus) to pass into the stomach but prevents food, drink, stomach acid and digestive enzymes (chyme) from flowing back up into the esophagus. The LES is aided in this task by the diaphragm. An incompetent LES fails to prevent back flow from occurring. An LES may be incompetent because it:

The stomach and its role in digestion The stomach is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines. Heartburn is a common symptom of the condition. 2  Peptic Ulcers – These can occur when the protective mucous lining of the stomach walls is damaged by the stomach acids. 3  The bacterium, Helicobacter pylori is thought to be an important factor in the development of gastric and duodenal ulcers.

UK on BST â not GMT â in the Summer The United Kingdom is not on Greenwich Mean Time (GMT) all year. During Daylight Saving Time (DST) the correct time zone is British Summer Time (BST). The UK observes DST from March to October every year. However, a lot of people aren't aware of this, which leads to mistakes when they use timeanddate.com services.

- CHANGES IN THE DIGESTIVE SYSTEM CAN GIVE RISE TO ULCERS. The digestive system is a marvelous feat of biological engineering. It is composed of discrete chambers (the mouth, esophagus, stomach, small intestine, and large intestine) that perform very distinct functions.

The Digestive Dangers of Smokeless Tobacco No matter what form it takes, smokeless tobacco products allow tobacco to be absorbed by the digestive system or through mucous membranes and can have similar effects on the digestive system as smoking. Health risks include heartburn, peptic ulcers, and an increased risk for Crohn's disease. The tobacco connection in digestive problems stems from the nicotine in tobacco, which causes the lower esophageal sphincter, or LES, valve to relax, allowing stomach acids to flow up to the esophagus.

- The digestive tractconsists of the oral cavity, pharynx, esophagus,stomach, small intestine, and large intestine. Mostof the absorptive functions of the digestive systemoccur in the small intestine, with smaller amountsin the stomach and large intestine.he pancreassecretes enzymes and buffers important to thedigestion of proteins, carbohydrates, and lipids.The activities of the digestive system are con-trolled through a combination of local reflexes,autonomic innervation, and the release of gastroin-testinal hormones such as gastrin, secretin, and cholecystokinin.
