Night terrors are fairly common in children, mostly between ages 3 and 8. Children with sleep terrors will often also talk in their sleep or sleepwalk. This sleep disorder, which may run in families, also can occur in adults. Strong emotional tension and/or the use of alcohol can increase the incidence of night terrors among adults.
The kidneys remove waste products and excess water from the body and so help to regulate blood pressure. They activate vitamin D, which helps to maintain strong bones, and produce erythropoietin, a hormone that is vital for the production of red blood cells.Each kidney contains 1.0-1.5 million small tubes called nephrons. The kidneys filter blood through a network of small blood vessels called the glomerulus.his helps to control blood pressure. In addition to making hormones, the kidneys also respond to a number of hormones including vitamin D, aldosterone, prostaglandins, cortisol, parathyroid hormone and calcitonin.
As you can see, the kidneys perform many functions that are important to your body: 1  Controlling the composition of your blood and eliminate wastes -- filtration/reabsorption/secretion method. 2  Influencing blood pressure -- renin secretion.  Helping to regulate your body's calcium -- vitamin D activation.
