common fatal hereditary disease amongst children and adults. It is an autosomal recessive disorder‚ and most carriers of the gene are asymptomatic. The flawed gene that causes CF affects the glandular secretions by altering chloride transport across cell membranes. Thickening of bronchial secretions leads to infection and other respiratory disorders. Other mucus secreting glands‚ sweat glands‚ and glands of the pancreas are also involved‚ causing electrolyte imbalance and digestive disturbance.

the hypothalamus secretes several hormones and is very closely related to the activity of the endocrine system. * The hormones it secretes are: * Releasing hormones – stimulate the secretion of specific anterior pituitary hormones * Release inhibiting hormones – inhibit the secretion of specific anterior pituitary hormones Pituitary * A small pea-sized gland also called the hypophysis. * Located at the base of the brain * Lies in the sella turcica (saddle-like

Enkephalins and Endorphins Do you have an experience that you cut your finger‚ it is painful in the few minutes‚ after that‚ it stops that feeling. Do you know why?

The active ingredient comes from a chemical class named benzimidazole and is broken down as: 5-methoxy-2-[[(4-methoxy-3‚ 5-dimethyl-2-pyridinyl) methyl] sulfinyl]-1H- benzimidazole‚ this compound inhibits gastric secretion. The empirical formula of Omeprazole is C17H19N3O3S‚ it has a molecular weight of 345.42 and has a structural formula displayed below: [pic](Rxlist.com‚ 2007) In New Zealand Omeprazole is available in four formulations.

large specimen cup. The osmolarity of blood plasma is within normal range at 275-295 mosmol/L of blood. Due to the fact that urine is the end product of our filtered plasma‚ it was an appropriate and noninvasive vehicle to demonstrate how ADH secretion works in regulating osmolarity. The experiment began when the groups drank the entire solutions and the time was noted for that. Once the experiment was in progress‚ the groups were instructed not to ingest anything until the lab was complete

Equine Reproductive System Tim Heckart In exploring the reproductive system of the horse we must first understand that this system is made up of physical structures and hormonal or chemical secretions‚ actions‚ and reactions. While the physical structures are readily identifiable‚ the hormonal systems are a bit more obscure. Some of these hormonal actions and reactions are still not fully understood today. We begin with the delivery of a Filly. At this stage in her life she already has all

Introduction: Diseases can be communicable or non-communicable. Communicable diseases are caused by infectious microorganisms which are pathogens. The aim of this passage is to discuss various types of microorganisms that cause disease. Microorganisms are simple organisms that are unicellular or live in colonies. The group contains bacteria‚ virus‚ algae‚ fungi‚ protozoa. They can be divided into pathogenic and non-pathogenic. In this passage pathogenic microorganisms that cause diseases are

STRUCTURE OF NEPHRON: Nephrons (Greek nephros=kidney) are renal or kidney tubules. Each kidney has over one million nephrons that are responsible for removing waste products from blood and maintaining water‚ salt and pH balance in the body. This vital job results in the formation of urine. 1.Afferent Arteriole * receives blood rich in oxygen from the renal artery. * blood is transported to the glomerulus of the nephron where it is pressure filtered. 2.Glomerulus * The glomerulus
