Islets of Langerhans

1. Which components of the digestive system are GI tract organs, and which are accessory digestive organs? The GI tract organs includes; The mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The accessory digestive organs include; The tongue, teeth, salivary glands, liver, gall bladder, and the pancreas 2. Which organs of the digestive system come in contact with food, and what are some of their digestive functions? Mouth is used for ingestion of food. Saliva…

6. SUMMARY AND CONCLUSION 6.1 SUMMARY The current study deals mainly with phytochemical and pharmacological investigation of traditionally used medicinal plant Enicostemma littorale Blume. A perusal of the literature revealed that only fragmental information was available on this plant species regarding cytoprotective potential and immunohistochemistry. In addition the exact molecular mechanism of action of this plant species active compound swertiamarin is unknown and remote. Hence this study…

Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the insulin and glucagon • Enzymes, or digestive juices, are secreted by the pancreas into the small intestine. There, it continues breaking down food that has left stomach. The pancreas also produces the hormone…

are excreted into the pancreatic duct. The pancreatic duct runs the length of the pancreas and drains fluid to the duodenum to the intestines. The second function of the pancreas is to release hormones such as insulin and glucagon from the islets of Langerhans into the blood stream helping control blood sugar levels (John Hopkins, 2015). In pancreatic cancer, tumors form in the pancreas due to abnormal division of cells, inhibiting the function of the pancreas. The most…

Type 1 diabetes mellitus is a chronic disease in which the body’s own immune system erroneously attacks the beta cells of the islets of Langerhans located in the pancreas that produce insulin, resulting in a high level of glucose in the blood. Insulin is needed to transport blood glucose (sugar) into cells. The sugar is then stored in the cells and used later for energy. “In these duties, insulin acts as a regulator of gene transcription” (Cox, 688). When beta cells produce too little or,…

food. Beta cells are located in the pancreas. The beta cell is a step in contact with getting diabetes. The bate cells make and release the insulin. Hormones control the level of sugar or glucose in your body. The beta cells are locate in the islets of Langerhans. The digestive system breaks down the food and moves…

The hormone insulin, is a main regulator of the glucose (sugar) levels in the blood. Insulin is released by pancreatic beta cells in the islets of Langerhan in response to elevated levels of nutrients in the blood. Insulin triggers the uptake of glucose, fatty acids and amino acids into liver, adipose tissue and muscle and promotes the storage of these nutrients in the form of glycogen, lipids and…

Type one usually affects children and teens, that’s why its called juvenile diabetes. It is thought to be autoimmune reaction, which includes genetic and virus factors that ruin the islets of langerhans cells. People with type one diabetes have to keep track of their blood glucose levels and take insulin (Scott 231). There is no known exact cause of type one diabetes. Ones immune system is suppose to fight off harmful viruses and bacteria…

Serotonin (5-HT) is an important neurotransmitter and paracrine signalling molecule in all bilateral animals, where it mediates gut movements and the animal's perceptions of resource availability. 5-HT was found in the gastrointestinal tract (GI tract), blood platelets, and the central nervous system (CNS) [1] [2]. Approximately 90% of 5-HT in the human body is synthesized and released in the GI tract, and the remainder is synthesized in serotonergic neurons of the CNS. 5-HT is synthesized from…

Mellitus Type One The etiology of DMT1 is not entirely clear, however, it appears to be caused by an autoimmune disorder that may be genetic in origin. The assumed immune dysfunction is an attack by the immune system on the beta cells in the islets of Langerhans of the pancreas. This would destroy or damage them enough to reduce and eventually eliminate insulin production. The autoimmune disorder may also need an environmental trigger to activate the attack upon the beta cells. There is a…
