Duodenum

Anatomy Consist of lips, tongue, teeth and salivary glands. Snout and Lips Folds of fleshy tissue located around the pig’s mouth. Skin and mucous membrane cover the pigs upper and lower lips. They contain a layer of connective tissue and labial glands (salivary glands). Their immobile and have and flattened upper lip. Incisors - Chiselled shaped teeth are located in the front and mid-section of the mouth. Canines – sharp pointed teeth located both sides of the mouth (top and bottom).…

work together in order to get food from one point of the body to the end. The major layers in the digestive tract include the submucosa (areolar tissue), muscularis externa (region of smooth muscle fibers), serosa that is located in the peritoneal cavity. The digestive tract includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. Some accessory organs of the digestive tract include the teeth, tongue, and various glandular organs such as salivary glands, liver and…

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,…

The digestive system is a group of organs that convert food into energy to feed the entire body. The alimentary is made up of the pharynx, esophagus, stomach, small intestines, and large intestines. Organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. In the digestive system it all begins with the mouth. Inside the mouth are many organs that help the food to be chopped up and swallowed . Teeth chop food into small pieces, which are…

Crohn’s disease is a recurrent infection that affects primarily the digestive system. It involves inflammation of the intestines both the small and the large intestines. It affects only the digestive tract of human beings. To enable one understand Crohn's disease, it is important to understand the whole digestive system and how it works in the process of digestion. The digestive system is made up of the digestive tract, the pancreases, liver and the gall bladder. Track refers to hollow organs…

2.5.1. Digestive system The digestive tract of the penaeidae shrimp is divided into three regions (Figure 4): namely, foregut, midgut and hind gut. The embryological origin of the epithelial cells in the foregut and hindgut are derived from the ectodermal and covered with cuticle. However, the epithelial cells of the midgut are derived from the entodermal origin. This region of the gut is lack of cuticle; however, it is lined by a peritrophic membrane (Lovett and Felder, 1989, 1990a, 1990b).…

Between thirty to fifty million Americans are considered to be lactose intolerant. Lactose intolerance is a common chronic digestive disorder in which a person’s intestinal tract lacks the ability to make lactase. It results from a drop in or disruption of the production of lactase in the small intestine. The small intestine is a primary part of the digestive system, and is the longest part of the gastrointestinal tract and makes up about three quarters of the digestive system. It is a hollow…

The Alimentary canal or gastrointestinal tract is made up of all the organs which food passes through during digestion. Starting from the mouth, where saliva is produced protecting the teeth and chemically breaking down food molecules and teeth are used to mechanically chew food from larger molecules to smaller molecules. Food is then passed through the Pharynx. The Epiglottis in the Pharynx, is a flap of tissue that covers the trachea to prevent food from entering the lungs, thus directing…

makes secretin when chyme enters the duodenum of the small intestines. Like others, secretin is made by special cells in the duodenum. As we have learned for some of the other hormones, secretin targets the stomach to make less enzymes and acid, and to make the mixing action slow down. More importantly, though, secretin also causes the liver to make more bile, while causing the pancreas to make bicarbonate ions. Bicarbonate ions are very important for the duodenum because in order for food…

midepigastrum abdominal pain is the pancreas. In the abdomen, the pancreas is located behind the stomach, between the spleen and duodenum. It is a long, slender gland that has a head, body and tail (Lewis, Dirksen, Heitkemper & Bucher, 2014). Peritoneum covers the anterior portion of the pancreas, while inside consists of lobes and lobules. The pancreatic duct enters the duodenum through the common bile duct (Lewis et al., 2014). Arterial blood enters through the branches of the celiac and…
