Acute Renal Failure Of The Urinary System

The function of ureters is to enter the urinary bladder at an angle to help prevent any back flow (reflux) of urine back into the ureter. The ureter connects the kidney to the urinary bladder and urine is drained from the kidney and stored in the bladder it’s a passage through which urine passes from kidneys to the urinary bladder.

Its main function is to produce and eliminate urine as a means of maintaining stable concentrations of salt, acids, and other electrolytes as well as to rid the body of toxic metabolic wastes for homeostasis. The kidneys produce the urine while the rest of the urinary system is what carries the urine out of the body. The ureters are a pair of tubes that carry the urine from the kidneys to the bladder by gravity and peristalsis of smooth muscle. The bladder stores the urine until the urine can be passed. When the bladder contracts, the urine enters the urethra, which is the tube that takes the urine from the bladder to the outside.

The renal system also known as the urinary systems purpose is to eliminate wastes from the body, regulate blood pressure, and regulate blood pH.

Every day the kidney’s filter on an average of about 120 to 150 quarts of blood that produces 1 to 2 quarts of urine that has extra fluid and waste. The importance of the kidney is to keep the blood stable so the body can function properly. The fluids that are removed from the body help prevent blood cells and large molecules (proteins) from passing. Once filtered it can pass through the tubule that sends minerals back into the blood stream to remove waste (niddk.nih.gov).

Actually, urinary system is not an isolated organ and is composed of kidney, ureter, bladder and urethra. Kidney plays the role of filtering blood, during which blood and wastes are separated. Filtered blood flow out of kidney through renal vein and wastes flow

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 wastes and extra water. That extra water and

As the glomeruli are part of the filtration system in the nephron of the kidney, damage can hinder removal of waste products, salt and water from the blood stream. Progressive destruction of

Chemically what is occurring is the digestive system is producing toxic substances that destroy red blood cells and eventually lead to the symptoms that were mentioned previously and the overall ending (if not treated) of kidney failure, among other possible health issues.

Acute Kidney Injury (AKI) is often characterized by a rapid decline in renal excretory function, and/or a significant decrease in urine output (SOURCE). The exact level of function loss required to be defined as AKI has been debated; however, the Acute Kidney Injury Network (AKIN) has released a widely accepted system used to define AKI and its varying levels of severity (1). The stages of AKI severity are classified as: risk, injury, failure, loss of function, and end-stage kidney disease, collectively referred to as RIFLE, as illustrated in Figure 1. Severity is defined based on glomerular filtration rate (GFR) and urine output criteria. GFR criteria includes serum creatinine concentration (Screat) and GFR, with an increase in Screat or a

Acute renal failure is a sudden decrease of kidney function often characterized by the loss of homeostatic equilibrium of the internal medium causing waste accumulation in the blood. Aside from accumulation of waste products like nitrogen and urea, it is also characterized by a sudden decrease of glomerular filtration rate (GFR) which disables the kidney from filtering waste products that is harmful to the body. Evidently, acute renal failure disables the kidney from maintaining fluid and electrolyte balance. As stated by kidneyatlas.org, causes for acute renal failure are classified into three: prerenal, intrarenal, and postrenal.

The renal system in the body pertains to the kidneys. The kidneys are the eliminators of waste in the body and collects the ions and elements that that body needs. There are two kidneys, one on each side of the middle to lower back. At

Acute renal failure can have either pre-renal, intra-renal, or post-renal causes. According to WebMD (2011), “the pathophysiology of pre-renal acute renal failure is a sudden reduction in blood flow to the kidney causes a loss of kidney function. In pre-renal acute renal failure, there is nothing wrong with the kidney itself.” The pathophysiology of intra-renal acute renal failure is when there is damage directly done to the kidneys from either inflammation, infection, drugs, toxins, or a reduced blood supply to the kidneys. The pathophysiology of post-renal acute renal failure is when there is suddenly an obstruction of the flow of urine because of a tumor, kidney stones, an enlarged prostate, or an injury. At the end of the post-renal acute renal failure stage, the next stage is chronic renal failure. As the stages

The Renal system, also known as the Urinary system, consists of the Kidneys, Ureters, urinary bladder, and urethra. The kidneys are in charge of filtering the blood to remove waste and that is when urine is produced. The urinary tract is made up of the ureters, urinary bladder, and urethra. The urinary tract is supposed to drain the urine from the Kidneys, store it and then releases it during urination. The Urinary system is also supposed to maintain the homeostasis of water, ions, pH, blood pressure and calcium. The Kidneys are in charge of regulating blood pressure, production of erythropoietin (controls red blood cell production in the bone marrow, regulate the acid base balance, and conserve fluids.

Acute renal failure occurs when there is an interaction of tubular and vascular. Primary cause is ischemia for more than two hours that result in severe and irreversible damage to the kidney tubules .Ischemia is caused by a reduction in GFR (glomular filtration rate) activation of the renin angiotensin system and tubular obstruction by cellular debris as nephrotoxins damage the tubular cells, these cells are lost through necrosis making tubules become more permeable, this results in filtrate absorption and causing the reduction in nephrons ability to eliminate waste. Acute renal failure is characterized by the following phases Prerenal, Intrarenal, and Postrenal.

How many of us really think about our ability to urinate, I know I never did, but for my Uncle and Cousin, they could only wish to do what comes so naturally to us. When you have kidney disease and suffer Renal failure, which is what both of my relative's had, the kidneys are unable to remove those wastes through urinating. When the kidneys no longer perform these functions adequately, wastes and excess fluid build up in the blood. Some of the warning signs of kidney disease are as follows:
