Large intestine

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.…

Almost every cell goes through a phase called the Cell Cycle this is where they cell grows and develops and then eventually splits into two cells. Why is this important? Well through the cell cycle it repairs damaged cells or replaces worn out cells. When you break your leg the cells work to get the bone healed or when you have a cut the cell cycle will help you by dividing cells to create a scab for your cut to heal. The cell spends most of its life in interphase, then it goes to the mitotic…

moves the food around. The food particles mix with saliva, which contains digestive enzymes, and becomes slippery. This enables the food to become easier to swallow, allowing it an easier passage as it move into the pharynx, esophagus, stomach, intestines, and finally the colon, which allows it to be evacuated from the body through the rectum. The oral cavity is important to the digestive system because it allows the food to be broken down into smaller pieces in order for it to enter the…

the biliary system, primarily functions to receive, concentrate and store bile produced by the liver. which used to assist the breakdown and absorption of fat in the digestive system (Drake et al., 2009). When food is consumed and enters the small intestine, cholecystokinin is released which triggers the gallbladder to contract and secrete bile. The gallbladder is not essential for survival however, as the liver will instead drip bile into the duodenum during this process instead if the…

The 44-year-old obese female is admitted to the emergency room with fever, severe abdominal pain on the upper right side that radiates to the scapula and nausea. I believe this patient is experiencing acute cholecystitis, gallbladder attack. The signs and symptoms of acute cholecystitis includes: intense or sudden pain in the upper right part of the stomach, worsening pain with deep breathing extending to the lower part of the right shoulder blade, shortness of breath due to pain, nausea and…

acids2. Finally, Creon will take any starches and will do the same thing; catalyze the hydrolysis of the starch into dextrins and other short-chain sugars2. All of the catalyzation of these molecules takes place in the duodenum and proximal small intestine, simulating the digestive enzymes that would be physiologically…

undigested materials are removed from a large pore known as Osculum. Earthworms, one of the organisms from our lab, is a Poriferan. Although earthworms do not have the exact same digestive system as other Poriferans, scientists still classify them in this subkingdom. Earthworms first begin digestion by drawing food into their open mouth through the rhythmic contractions of the pharyngeal muscles. From the mouth, food goes into a small buccal cavity that opens into a large pharynx. The pharynx…

To understand KBs diagnoses of pancreatitis it is first important to understand the function of the pancreas. The pancreas works as both an exocrine and endocrine gland. The endocrine portion of the pancreas includes the production of Insulin from beta cells, and glucagon from alpha cells which are released into the bloodstream to help regulate blood sugars.1 The pancreas works as an exocrine organ by secreting digestive enzymes that are released into the duodenum through the common bile duct…

Small Intestine The contents from the stomach reach the small intestine once they have been sufficiently processed. The small intestine is a long muscular tube that releases enzymes to further break down the molecules. There are three sections to the small intestine, the duodenum, jejunum, and ileum. The continuous break-down process is mainly achieved in the duodenum, while the jejunum and ileum provide the bloodstream with nutrients. Once the content has passed through the lower intestine, it…

Box jellyfish Nomenclature "Box jellyfish" and "sea wasp" are common names for the highly venomous Chironex fleckeri. However, these terms are ambiguous, as "sea wasp" and "marine stinger" are sometimes used to refer to other jellyfish. Anatomy "Cubomedusae", from Ernst Haeckel's Kunstformen der Natur, 1904 The medusa form of a box jellyfish has a squarish, box-like bell. From each of the four lower corners of this hangs a short pedalium or stalk which bears one or more long, slender, hollow…
