Large intestine

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)…

The digestive system is a series of hollow organs that form a long tube that extends from the mouth, through the abdominal cavity, and ends at the anus. It consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs such as the salivary glands, liver, gallbladder and pancreas. The digestive tract contains food from the time it is consumed until it is either absorbed by the body or eliminated; muscular contractions of the digestive tract help to…

Introduction The gastrointestinal tract (GI) comprises of the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and the anus. Also, digestion process start from the mouth; the ingestion of food stimulate the salivary secretion (mouth), the food is chewed before its passage through the esophagus down to the stomach where mechanical and chemical digestion takes place. Pepsinogen from the chief cells helps with the digestion of protein, amylase from the saliva and…

Ulcerative Colitis, Pediatric Ulcerative colitis is long-lasting (chronic) inflammation of the large intestine (colon). Sores (ulcers) may also form on the colon. Ulcerative colitis, along with a closely related condition called Crohn disease, is often referred to as inflammatory bowel disease. CAUSES Ulcerative colitis is caused by increased activity of the immune system in the intestines. The immune system is the system that protects the body against harmful bacteria, viruses, and other…

juice is 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)…

of animal uses the mouth opening, and often teeth, to acquire the food regardless of what stage—live, raw, cooked, etc.—and introduce it to the digestive tract. Almost all animals have a small and large intestine, wherein the separation and absorption of nutrients occurs. At the end of the small intestine the caecum is found in almost every mammal, although the size among types of eaters varies. The un-digestible waste travels through the bowels and exits from the anus as feces. Because…

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…

Whipple Procedure Whipple procedure is a surgery to remove the head of the pancreas, the upper part of the small intestine (duodenum), and the organ that stores fluid (bile) made in the liver (gallbladder). Part of the stomach may also be removed during this procedure. The pancreas is a large gland located behind the stomach. It helps digest food and it produces hormones that regulate blood sugar. The head of the pancreas is the part that is connected to the duodenum. A Whipple procedure may…

The small intestine consists of three divisions: The duodenum is the uppermost division and the part to which the pyloric end of the stomach attaches. it is about 25 cm (10 inches) long and is shaped roughly like the letter C. The name duodenum , meaning " 12 fingerbreadths," refers to the short length of this intestinal division. The duodenum becomes jejunum at the point where the tube turns abruptly forward and downward . The jejunal portion continues for approximately the next 2.5 m (8…

1. Detail the first part of the digestive system from the mouth to the esophagus including the structure and functions of each part. The first part of the digestive system is comprised of the mouth, the pharynx and the esophagus. The mouth is an oral cavity that starts the process of mechanical and chemical digestions when food is received. The mouth is bounded by the cheeks and lips. The mouth contains a soft and hard palate, salivary glands, teeth (crown and dentin) and the tongue (covered…
