Jermel Chaney 11/15/2012 Mod E Glomerulonephritis Glomerulonephritis is some type of kidney disease in which the part of your kidneys that helps filter waste and fluids from the blood is damaged. Its caused by the problems with body’s immune system. Often‚ the exact cause of glomerulonephritis is unknown. Damage to the glomeruli cause blood and protein to be lost in the urine condition may develop quickly and kidney function is lost within weeks or months. A quarter of people with chronic

Shock is a life threatening condition that occurs when the organs and tissues of the body are not receiving an adequate flow of blood. In a sense the circulatory system is failing to effectively deliver oxygen to the cells thus resulting in reduced tissue perfusion. It is characterised by hypoxia and inadequate cellular function that lead to multiple organ failure and potentially death (Kleinpell 2007). This essay will focus on hypovolemic shock in particular‚ and relate it to patient with complications

The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys‚ collected in the bladder and excreted through the urethra. Urine is used to extract excess minerals or vitamins as well as blood corpuscles from the body. The Urinary organs include the kidneys‚ ureters‚ bladder‚ and urethra. The Urinary system works with

nueurohormaonal mechanisms stimulate. Epinephrine and Norepinephrine are released by the sympathetic nervous system. After the heart begins to have a decrease in renal perfusion there is a release in renin then the formation of angiotensin I. This is then converted into angiotensin II which makes the blood vessels constrict and activated the release of

They include‚ sympathetic nervous system stimulation‚ Renin=angiotensin system activation‚ other chemical responses‚ and myocardial hypertrophy. 3.

Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:

mechanisms for controlling blood pressure: (1) cardiac input and output equilibration‚ (2) blood volume maintenance‚ (3) endocrine control‚ (4) peripheral resistance (systemic vascular resistance) maintenance‚ (5) baroreceptor reflex‚ and (6) the renin-angiotensin system (Foxall‚ 2009). All six mechanisms work independently of one another but also can have positive or negative effects on each other. The mean arterial pressure can be related to arterial blood volume.
