Zacharys Story Essay

The name for these erosions is aphthous ulcers. These erosions, after a while, start to deepen and grow in diameter. Once they reach a certain size, they can be referred to as ulcers. These ulcers can cause scarring and they can also cause the bowel to become stiff and lose its elasticity. As Crohn’s worsens, the bowel becomes obstructed once the passageways narrow enough. This obstruction can cause a buildup of food that is still being digested, fluid and gas that comes from the stomach. This obstruction will then prevent all of those products from entering into the colon. This will cause severe abdominal cramps, nausea, vomiting, and even abdominal distention. If the ulcers located in the walls of the bowel become large or extreme enough, holes can form in the walls of the bowel. Once those holes are formed in the bowel, the bacteria normal to the bowel can then pass through those holes and spread to nearby organs and into the abdominal cavity causing what are called fistulas. These fistulas are like a channel/tunnel that is formed between the ulcer and the adjacent organ. Then when a fistula is created between the affected intestine and the bladder, it is called an enteric-vesicular fistula which can lead to UTI’s and feces being presented during urination. Next, when the fistula is formed between the intestine and skin, it is called an enteric-cutaneous fistula. What this fistula, pus and mucous exit the body through a painful opening found in the skin of the

The small intestine is responsible for absorbing food and nutrients. Thus, damage to the lining of

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

G.) Would absorption of nutrients be substantially altered in the small intestine following Chloe’s gastric bypass surgery?

3) Once a bolus of food has been formed in the mouth, it is passed by the tongue and jaws to the

3. Specifically state where in the intestine sucrase is likely to be most active (pH along GI tract).

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

The stomach 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 each organ requires different cell types, why the stomach can’t be comprised of just one cell type, and the advantage of having different types of cells.

Purpose: The purpose of this lab is to understand the process of digestion. In addition, to investigate what chemicals and enzymes are needed for carbohydrate, protein, and lipid digestion.

Have you ever heard about ulcerative colitis? For those that have not or might want to know a little more information regarding this disease here are in this essay you will learn the definition, risk factors, symptoms, if there is any treatment to cure and many more important details that many of us should take into consideration.

The vessels inside the lining also break down causing the patient to bleed. Depending where the ulcer is will the patient present with Hematemesis or Hematochezia. Another complication could be perforation of the stomach. This allows gastric contents to release into the sterile portion of the abdominal cavity. This could cause a severe infection and often requires surgical repair. The third major complication could be obstruction. Often if a ulcer presents in the narrow part of the distal stomach, an obstruction can occur. That is because scar tissue grows back often occluding the path of gastric contents. Surgical repair would also be necessary in this

After Matt and Maria eat their food, enzymes in the digestive system break the proteins,

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.

Bella is in a fight with her pet cheeseburger Ebenezer because he got ketchup all over her new white shirt. Though in the end, she concludes to solve her problem by eating him. Primarily, Ebenezer, the cheeseburger, enters the digestive tract through the mouth in which he is cut, torn, and grinded into pieces through mechanical digestion, in which Bella can swallow by her teeth. Bella’s saliva then helps her soften, moisten, and break down the starches of Ebenezer so that she is ready to swallow him. This is when ingestion happens or the process of taking in food. In swallowing Ebenezer, Bella closes a trap door in her throat known as the epiglottis. Suddenly, Ebenezer is in her pharynx, which hands him to her esophagus, which carries him to

The primary function of the digestive system is to transfer nutrients, water, and electrolytes from the food consume into the body’s internal environment. The ingested food is essential as an energy source, or fuel, from which the cells can generate ATP to carry out their particular energy-dependent activities such as contraction, transport, synthesis, secretion and even renewal of body tissues. Three primary categories of food ingested by humans which are carbohydrates, proteins and fats emerge as large molecules. These large molecules cannot cross plasma membranes intact to be absorbed from the lumen of the digestive tract into the blood or lymph; hence, it must undergo degradation in size (Sherwood, 2013).
