Intestine

Open Small Bowel Resection Small bowel resection is surgery to remove part of the small bowel. The small bowel, also called the small intestine, is the top part of the intestines. It is part of the digestive system. When food leaves the stomach, it goes into the small bowel. Most food is then absorbed into the body. A small bowel resection may be needed if the small bowel becomes blocked or harmed by disease. One type of procedure is called an open resection. This means the surgeon will make…

Celiac disease. What is Celiac disease? Celiac disease is a disorder of the digestive tract which damages the small intestine and inhibits the absorption of nutrients. People suffering from Celiac disease cannot tolerate the gluten protein. When gluten is ingested, their immune system sees it as a foreign body, damaging the villi, small finger-like protrusions, in the small intestine.…

body. However, the gastrointestinal microbiome is one of the most complex and dense populations studied (Todar, 2012). The mammalian gastrointestinal tract is comprised of about four million bacterial genes with more than 95% located in the large intestine (Galland, 2014). The gastrointestinal microbiota varies along the tract at longitudinal levels and horizontal levels due to particular bacteria attaching to the epithelium in the lumen (Todar, 2012). With DNA sequencing and metagenomic studies…

The mouth which is also called the oral cavity is associated with the accessory organs such as teeth, salivary glands, and tongue. The mouth is where digestion starts. Our teeth are used to chew food into really small pieces and our saliva contains enzymes that begins the process of digestion. Our tongue occupies the floor of the mouth and mixes food with saliva to form bolus which is a compact mass that forms food into a lump that helps initiates swallowing. The mouth begins the process of…

• Small intestine: Most of the digestion takes place in the small intestine. Between the stomach and the large intestine. • Large intestine: The final section of the GI, main function absorbs remaining water & vitamins left over from the small intestine. Then transfer waste material into feces. The accessory digestive organs act as an assistant that helps to breakdown food, consist…

The digestive system consists of the oral cavity, oesophagus, stomach, liver, gall bladder, spleen, pancreas,intestines, appendix and the rectum. All these organs interlink in order to carry out an environment of homeostasis. Homeostasis is a state of equilibrium inside the body as stated in the Journal of Nursing Standards (Hendry C 2012 page (46-50)).A further consideration is that of legal and ethical concerns within practice. The first part of the digestive system is the oral cavity and…

edema was noted on the physical examination, and the abdominal examination was negative for distention and organomegaly. Question: Describe the pathophysiology and clinical presentations associated with small intestine malabsorption. Generate: Malabsorption occurs when the small intestines are unable to appropriately absorb nutrients. Additionally, it can occur diffusely where several nutrients are not absorbed, or partially causing nutrient-specific malabsorption. Normally, three steps are…

those that smoke cigarettes, family members with inflammatory bowel disease (IBD) and Jewish descent. Crohn’s disease is chronic, causing abnormal inflammation in the gastrointestinal (GI) tract, affecting the end of the small intestine to the beginning of large intestine. It affects the mental and physical capacity of the individual, causing one to feel worthless and depressed because of the complications from the disease. The Crohn’s disease is classified with inflammatory bowel disease (IBD)…

Heterotrophs are sectioned off into three different categories based on their intake of food. Heterotrophs are organisms that use organic compounds for energy and carbon. Herbivores, being animals that eat plants are; algae-eating snails, sapsucking insects, and vertebrates such as cows, horses, rabbits, and sparrows. Carnivores, animals who eat other animals; crabs, squid, many insects, cats, eagles, trout, and frogs. Omnivores, animals who eat both plants and other animals are; humans, pigs,…

third innermost oblique layer relates to the function of the stomach because it is the smooth muscle that is responsible for the churning function of the stomach that aids in its ability to digestive and move food from the stomach into the small intestine. The gastroesophageal junction is the junction between the esophagus and the stomach. The epithelium changes from…
