Essay on The Digestive System

Gastroparesis is a digestive disorder in which the motility of the stomach is either abnormal or absent. "Gastro" means stomach and "paresis" means weakness. Gastroparesis is a weak stomach. This condition is very common. It can be the cause of a number of abdominal complaints. It is usually not a serious problem and there are effective treatments available.

* If a person needs feeding, make sure to give enough time for them to chew and swallow the food.

The above explanation of digestion occurs in a ‘normal’ functioning body. There are several dilemmas involving digestion that the human body may encounter with progressed age, disease, or improper mechanics, such as lack of teeth. A major threat involving a decrease in digestion ability is malnutrition. Malnutrition does not simply refer to not eating, but also encompasses insufficient absorbance of nutrients once food has been eaten. There is a wide array of factors that may lead to malnutrition in an individual. Mechanically, the lack of teeth is a simple but yet common reason of decreased nutrition intake. Though salivary glands are stimulated upon the introduction of food to the mouth, a person with no teeth tends to avoid the more strenuous foods to chew, such as meats, carrots, lettuce, and nuts, and become partial to a lot of soft foods like potatoes and eggs, which may not necessarily be the most nutritious or balanced. Individuals with gum disease may have all their teeth, but it can become sore for them to chew their meals and, as a result, the eating dwindles. Jaw injuries or surgeries can cause discomfort and may temporarily hinder proper

D2 how the digestive system, cardiovascular system and respiratory system all link together How the digestive system works? Food moves through the GI tract. Digestion starts in the mouth with chewing and finishes in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

The American College of Gastroenterology Guidelines recommend colonoscopy,as the preferred cancer screening test for patients 50 years and older(Rex 2017). The technique of Endoscopic Mucosal Resection (EMR) was developed for removingsessile or flat lesions confined to the superficial layers (mucosa and submucosa) of the gastrointestinal (GI) tract, including the colon, esophagus, stomach, and duodenum. EMR with submucosal injection helps facilitate complete resection of polyps (Hwang 2015; Fyock 2010; Steele 2013), which is critical, as incomplete resections may contribute to the development of colon cancer in patients despite being on a colonoscopy screening/surveillance pathway (i.e. interval cancers).

Gastroschisis is a birth defect that prevents an infant’s abdominal wall from closing properly causing the intestines to stick out of a hole next to the umbilical cord1. Other abdominal organs may protrude out of the abdominal cavity as well, including the stomach and liver, and lack covering from the peritoneal membrane2. It is believed that gastroschisis takes place between the 4th and 8th week of development of the fetus2. Due to the lack of protective covering, the protruding intestines may become inflamed due to contact with amniotic fluid2. According to the CDC, almost 2000 babies a year are born in the United States with this abdominal wall defect3. Although the cause for gastrochisis is not clear, it is found to be most prevalent among mothers who smoke, who are younger than 20, or who are Hispanic among other factors2-5. The CDC states that the frequency of gastroschisis is increasing in the United States and the rates have doubled among African American Mothers4.Due to the nutrition-related complications associated with gastroschisis, it is important to review current research to inform better feeding practices.

The function of the pancreas has a substantial part in the regulation of the digestive system. The small intestine alongside the pancreas also contributes many features to the signaling pathways protein and other major enzymes must undergo before reaching the exocytosis stage. Specific hormones and receptors help in the necessary release of such enzyme. Secretagogues initiates particular signals throughout the progression and development of the digestive system. The enteric nervous system will later address the complexity of neurotransmitters as well as intra and extracellular mechanisms.

Being assigned the position of a ruler is a big honor and responsibility. As the ruler of a country, one must be wise in making important decisions, know what’s in the country’s best interest and be prepared and mentally ready for anything (Front Branching Subordinate). Prince George IV, The Voluptuary, displays many attributes that would clearly make him unfit to be a good leader (Appositive).

The stomach is an expandable muscular sac that is capable of holding 2-4 liters of food and liquids and breaks them down with the use of pepsinogen, an inactive form pepsin, a protein-digesting enzyme. If the stomach was damaged or dysfunctional, then it would be harder to gradually release food into the small intestine at a rate suitable for proper digestion and absorption and to digest the food because it is not as small or digested because the stomach also assists in the mechanical and chemical breakdown of the food as well as the killing of harmful bacteria due to the high acidic environment due to the hydrochloric acid.

Get ready for the dangerous ride of a banana getting crushed, smashed, and absorbed through the digestive system. “Watch out for the involuntary muscles which they can’t even control and voluntary muscles they can control, but will still use thriving to help get our nutrients by crushing us.” everyone has always said but, that didn’t stop him. Once Banana was ripe enough the farmer has picked him. Banana thought is was chosen for an amusement park. because everyone else says it’ll be like a scary rollercoaster, he took it literally…

When apples, bananas, and other fruits are cut, they begin to turn brown in a short amount of time. This brownish color is called benzoquinone. Benzoquinone acts as an antiseptic in this reaction, and it causes fruit to turn bad quicker than desired.

Mucins are large secreted and/or transmembrane glycoproteins, predominantly expressed on the luminal surfaces of wet epithelia.
