The Urinary System plays an important role in our everyday life. It’s most important functions are maintenance of homeostasis, manufacture hormones that we need, and to process our wastes for elimination. Our kidneys are part of this whole system; bad habits and lifestyle affect the whole cycle. This system has a long list of disorders and diseases that an individual may acquire; one of these is Acute Renal Failure (ARF). Its fast development impairs the kidneys- unless the problems detected immediately and treated.
Acute Renal Failure causes the kidneys to stop abruptly working. It loses its functions to eliminate wastes, maintain fluid balance, and preserve our body’s electrolytes. Blood enters the kidneys through the renal arteries and leaves through the renal veins. The strength of pressure exerted onto the kidneys is what makes the glomerular filtration work. The glomerulus, or the capillary network inside the Bowman’s capsule, is a filtration system. This pressure depends upon the flow of blood and the resistance between the afferent and efferent arterioles. The afferent arterioles bring the blood; while the efferent arteriole takes it away. When blood flow obstructed, the glomerular filtration rate (GFR) decreases. The GFR is a test used to check how the kidneys are working; it measures how much blood passes through the glomeruli every minute. This pathology leads to the underlying cause of acute renal failure. It has three origins: perineal, intrarenal, and post-renal or obstructive (Workeneh, 2013).
In perineal, the tubules and the glomerulus remain normal. It happens when a sudden decrease of blood flow to the kidney causes loss of the kidney’s functions. There are several causes, which include cirrhosis, severe dehydr...

...client’s fluid volume status is the daily weight. In addition, a good short term goal to include is for the client to have a urine output of at least 30ml/hr. Right teaching about acute renal failure from nurse to a client is significant as well to achieve the desired effectiveness of treatment.
Long term goals involve the prevention of further complication of the disease. Usually this pertains to clients who are going through dialysis and renal transplant. In dialysis, the goal is to remove the end products of protein metabolism, such as urea and creatinine, from the blood. Serum electrolytes should be maintained at a safe concentration. In addition, acidosis must be corrected to replenish the blood’s bicarbonate buffer system. In renal transplant, the goal is to prevent infection and organ rejection as well as to maintain therapy for the rest of the client’s life.

The Function Of The Urinary System Essay

- The urinary system is made up of a paired kidneys, the bladder, urethra, and the ureters. Kidney plays an important role of maintaining homeostasis by regulating the volume of fluid in the body. It is essential for renal system maintaining homeostasis through regulation of pH, ECF (extracellular fluid) volume, solute concentration, and ion composition in order to preserve a proper fluid volume in the body. The other important functions of renal system are excreting foreign chemicals, toxins, and metabolites out of the body....   [tags: Kidney, Glomerulus, Nephron, Renal physiology]

The Function Of The System Essay

- The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating....   [tags: Kidney, Urine, Ureter, Urinary bladder]

- ... The left kidney sits slightly higher than the right due to the position on the right side of the internal cavity of the liver, and on the apex of both kidneys sits an adrenal gland. The adrenal gland releases a number of different hormones directly into the bloodstream including aldosterone, a hormone which controls electrolyte balance within the body and the ability to control sodium levels. Electrolytes come from the food and fluids we take on board. When the fluid levels within the body change, the electrolyte levels change and this can alter the balance of the blood composition, muscle function and other system processes....   [tags: kidneys, organic substances, waste release]

- The gamma camera has been the mainstay treatment pillar in the department of the nuclear medicines in the past four or so decades. When natural radioactivity was discovered by Henry Bequerel in 1896, the development of the nuclear medicine started; a year before the discovery of the X-rays by Wilhelm Rontgen. It was then found that these rays could be used for therapeutic and diagnostic purposes for patients, a process that became a clinical routine in the 1920s. A series of discoveries in the 1940s and 50s in the field of nuclear medicines saw milestones of developments in the department, especially the 1950s....   [tags: Kidney, Ureter, Urinary system, Urinary bladder]

Essay on Urinary Tract Infections

- INTRODUCTION In the human body, there are systems that provide different functions and help the body to operate more efficiently. The urinary system is one in particular designed to help the body remain free of excess that we no longer need. “The urinary tract is the drainage system used for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are a pair of “bean-shaped” organs, each about the size of a fist. The kidneys are located below the ribs, one on each side of the spine, towards the middle of the back.” (NIDDK, 2013) Every several minutes, your kidneys filter around three ounces of blood, also then removing wa...   [tags: Radionuclide Scan, Catherer]

Kidney Function Essay

- Kidney Function Introduction and definition of terms: The kidneys are the main organs in the urinary system. They filter waste products out of blood from the renal artery. These are then excreted. Useful solutes are reabsorbed into the blood. They also have a major homeostatic role in the body, and help to control the water content (osmoregulation) and pH of the blood. Homeostasis is the maintenance of a constant internal environment within a living organism. Excretion is the removal from the body of waste products made in the cells during metabolism....   [tags: Papers]
