The endocrine part of the pancreas consists of pancreatic islets (islets of the Langerhans). Insulin and glucagon are hormones secreted by islet cells of the pancreas. Both of these hormones are secreted depending on the blood glucose levels. Alpha cells of the pancreatic islets secrete glucagon and beta cells of the pancreatic islets secrete insulin (Marieb‚ 2012). Insulin and glucagon are equally important in managing blood glucose‚ making sure the body functions well. Glucose‚ which comes from

BREAKDOWN OF METH IN BODY- Introduction- Methamphetamine is generally referred as “meth”. It is often used for many reasons such as to attain a short-term joy‚ improve sexual experiences‚ promote insomnia and enhance motivation. The breakdown of Meth – When methamphetamine is ingested‚ it affects the digestive system. Here is the procedure of breakdown. The Alimentary Canal - Meth mouth is used to describe a meth consumer’s the rotten and decayed teeth; there are many reasons why this happens

unchanged from the normal state. Without the cystic fibrosis variation of the CFTR gene‚ the CFTR proteins created by the gene act as a channel protein which can be found in the membranes of cells which line the passageways of organs such as the pancreas‚ lungs‚ and intestines. The CFTR protein can be modified in numerous ways to give the host cystic fibrosis; in fact‚ over 1000 transformations of the CFTR gene have been recognized. One of the most common of these mutations is a deletion of a single

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. - Anatomy is the study of the structures and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. The kidneys remove wastes and water from the blood. 2.

Chronic Disease Risk Assessment Diabetes is a chronic lifelong disease where there are high traces of sugar in the blood. A diabetic individuals pancreas secrets an insufficient amount of insulin or does not use the insulin efficiently. Insulin is a hormone made in the pancreas that enables the body to use glucose for energy. Diabetes is caused by too little insulin‚ resistance to insulin or both. Diabetes is the most common disorder of the human hormone system; there are three forms of diabetes

Just as an iPod needs a battery‚ your body needs glucose to keep running. Here’s how it should work: 1.You eat. 2.Glucose from the food gets into your bloodstream. 3.Your pancreas makes a hormone called insulin. 4.Insulin helps the glucose get into the body’s cells. 5.Your body gets the energy it needs. The pancreas is a gland near your stomach that helps your body digest food. It also makes insulin. Insulin is like a key that opens the doors to the cells of the body. It lets glucose in.

if the blood glucose level begins to decline‚ the pancreas releases the hormone glucagon‚ which then stimulates cells to release glucose into the blood stream. Now when the blood glucose starts to rise‚ the pancreas releases another hormone which is insulin. Insulin does the opposite of glucagon; it stimulates the cells to remove glucose from the blood. Diabetes is when the body has excess amount of glucose in the blood stream due to the pancreas not secreting enough or no insulin. This causes a

effects on the body‚ but it mainly affects the digestive system‚ pancreas and the lungs. Inside the lungs‚ the mucus can clog the airways and trap bacteria. This more often leads to infections‚ lung damage and eventually‚ respiratory failure. Inside the pancreas‚ the mucus stops the release of digestive enzymes that allow the body to break down food and absorb vital nutrients‚ which can sometimes lead to inflammation of the pancreas. Cystic fibrosis can also affect other parts of the body‚ that includes
