Your kidneys play a very important role in helping your body function properly. The kidneys help your body pass waste as urine and helps filter blood before it’s sent back to the heart. Kidneys are two bean shaped organs that are about the size of a fist. Most people have two kidneys that are located just below the spine, one on each side of the spine. Your kidneys perform many vital functions for your body. They produce hormones that help produce red blood cells, regulates blood pressure, and promotes healthy bones. Even though they play such a big role, it is possible to only live with one kidney. There are many illnesses that impairs the functioning of the kidneys, one of them is Acute kidney injury. Acute kidney injury is also known
The kidneys are located in the posterior section of the retroperitoneal cavity and are small, dark red kidney-bean shaped organs in the lower part of the rib cage (Marieb, The Urinary System, 2015). They are undervalued organs considering how essential they are for the body’s ability to maintain homeostasis. The kidneys filter about 120-150 quarts of blood to produce about 1-2 quarts of urine each day (NIH, 2014). Blood initially enters the kidneys through the renal artery. It then flows into the segmental artery before moving into the interlobar artery. From the interlobar artery the filtrate enters the arcuate artery before branching into the cortical radiate artery, which feeds into the afferent arteriole, before passing into the glomerulus where it begins to filter out waste. The filtered waste is then collected by renal tubule. The tubules drain to collecting ducts and all of these components together makes up a small unit called a nephron. Each kidney has over a million nephrons (Marieb, Blood Supply/ Nephrons, 2015). They filter out wastes that run through different body systems via blood; the majority of that waste is nitrogenous wastes, toxins, excess fluids, electrolytes, and drugs. These waste products are eliminated as urine. While waste are removed vital enzymes, hormones, and water are returned
Kidneys play an important role in the unary tract. They are located on each side of the spine, just below the ribcage. Each kidney is connected to the bladder by ureters. The kidneys have many functions, but the most common functions are to clean waste, control chemicals, and regulate fluid in the body which makes up the urine. Urine collects in the kidney before entering the ureters and as time passes more materials are added. When calcium and oxalate or phosphates are combined in the kidney tiny stones are formed called nephrolithiasis, commonly known as kidney stones. These stones can be very painful and “increases risks for diabetes, high blood pressure, and osteoporosis” (Goldfarb, 2009). About ten percent of all people will have kidney stones in their lifetime. Kidney stones are most frequently found in white men over the age of forty, relatives of kidney stone patients, and people who have formerly had kidney stones.
Four days after winning the Seagate 100 km Ultramarathon in Toledo, Ohio, I was hospitalized for 11 days with Acute Kidney Failure, a direct consequence of the race, possibly exacerbated by the 2400 mg of ibuprofen that I took during the race. In this article, I will describe my race and my hospitalization, discuss similar experiences of two runners after the 1994 Western States (WS) 100 Mile Endurance Run, and tell what I have learned that might be of general interest.
The urinary tract consists of two kidneys, to ureters, urethra, and the urinary bladder. The urinary system works to remove waste from the body, maintain homeostasis of water, blood pressure, and regulate the body’s pH levels. The kidneys regulate several important internal conditions by excreting substances out into the body. After urine has been produced in the kidneys it is then transported to the urinary bladder via the ureters. The urinary bladder then holds the urine until the body is ready for excretion through the urethra.
Introductions Throughout our body we have many majors organs and each organ has a major function on our body. One of the major organs of the urinary system is the kidneys. We have 2 reddish brown, fist size, bean shaped kidneys in our body located on the anterior side by the lower edge of the ribs on either side of the spinal cord. The major function of your kidneys is to filter the blood to remove waste products, helps balance water, salt, electrolytes and forms urine. There must be an adequate blood supply in order for the kidneys to function properly. When your kidneys suddenly shut down and stop working it’s called acute renal failure. Acute renal failure is the most common leading deaths in hospitals today.
The renal disease are common nowadays .The acute renal failure is a medical term means that the kidneys stopped from working and not able to clear toxins from body ,not able to maintained a stable electrolyte balance inside the body and not able to secret the extra fluid as urine outside the body. The renal replacement therapy (RRT) or dialysis has been discovered on 1913 by Able, Rowntree and Turner in London, UK.
Without proper working kidneys, blood pressure can rise, body fluids accumulate and red blood cell count can decrease. Usually kidney problems occur from disease, conditions and disorders. Disease can come from damage to nephrons, which help filter the blood. Infections can travel from the bladder up to the kidneys. Kidney cancers, kidney stones, cysts and injury all can damage a kidney. Without properly working kidneys, our heart, lungs and brain, as well as other organs are put in danger. (Capicchiano 2013) Kidney dialysis is not always a permanent need; sometimes it is needed for a short time. Kidney dialysis can occur in many places, the hospital, a home or in a center. Often people return to work after dialysis, unless their job involves strenuous activity such as heavy lifting or digging. (Lewin, 2010)
Lets begin by discussing the big picture view of the urinary system. It is comprised by the kidneys, ureter, bladder, and the urethra. Referring to the anatomical position the right kidney is lower than the left kidney due to the liver being large. In a transverse cut and view from above one can see that the digestive organs are in a separate cavity from the urinary system. The peritoneal cavity houses the digestive organs and it houses serous membrane which secretes a small amount of fluid in the cavity that lubricates organs so that they experience very little friction as they move about inside of the body. The kidneys are in the retroperitoneal cavity, literally that means behind the peritoneal cavity. Unlike the digestive organs the kidneys are not allowed to move much when the body moves. They are held in place by perirenal fat, this fat firmly holds them in place. If someone gets to abnormally thin the kidneys can slip causing the ureter to get pinched.
The kidneys are bean shaped organs. They are a brownish-purplish sort of color. The outside of the kidneys are very tough, but smooth. This is described as a fibrous tunic. The outer part has millions of nephrons which are the basic unit of the kidney. The kidney is divided into two layers. The outer cortex and the medulla. When the outer cortex is stripped off you then get the medulla. The inside you have a thick mesh of muscular fibers. This is also smooth, and very even. It is very red in color, unlike the outside which is of brownish-purplish coloring. It is more red in color because it has tiny blood vessels. The kidneys are located in the posterior part of the abdomen, on both sides of the vertebral column. An easier way to say that would be right below the ribs towards the middle of your back. The right kidney is usually lower in location than the left kidney because of where the liver is. Each kidney is about 11cm long, 6cm wide, and 2.5 cm thick. The kidneys remove urea from the blood through a blood filtering unit called a nephron. There are more than 2 million nephrons in each kidney. The nephron is part of the homeostatic mechanism of your body. That mechanism maintains your water-salt balance, and it also regulates the amount of urea in your body. The blood enters the kidney through the bowmans capsule under pressure. This just surrounds the tuft of capillaries which is the glomerulus. The liquid just flows through the glomerulus under pressure. The pressure pushes the liquid out and keeps in the larger cells. This is filtration, because the glomerulus is taking the nutrients in and getting rid of the waste. After the filtering ...
The urinary system is composed of the kidneys, the ureters, the urinary bladder, and the urethra ("Urinary System", n.d.). These organs and tubes shape what is called the urinary tract, the body’s drainage system for removing urine from the kidneys, storing the urine, and then expelling it during urination ("Urinary System", n.d.). The first part of the urinary system is the kidneys. The kidneys are a pair of bean-shaped organs located in the upper abdominal cavity against the back muscles ("Urinary System", n.d.). The kidneys are responsible for filtering the blood to remove waste and chemicals to produce urine ("Urinary System", n.d.). Blood is carried through the renal arteries to the kidneys where they are filtered by nephrons - tiny filtering units in both kidneys that remove harmful substances and waste from the blood (Durani, 2015). The toxins and waste sifted by these nephrons are blended with water to produce urine (Durani, 2015). On average, the kidneys will filter 120 to 150 quarts of blood a day to produce about 1 to 2 quarts of urine ("The Urinary Tract & How It Works", 2014). The next
Healthy kidneys clean the blood by filtering out extra water and wastes. They also make hormones that keep your bones strong and blood healthy. When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys.
All play a role in removing waste from your body. Your kidneys filter waste from your blood and regulate the concentrations of many substances. Tubes called ureters carry urine from your kidneys to the bladder, where it’s store until it exits your body through the urethra.
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.
Furthermore, they are involved in the reabsorption of nutrients in the bloodstream and they can regulate the acidity of the blood. Besides the regulation of the fluids and ions, the kidneys are also responsible for the regulation of many different hormones that are involved in homeostasis and metabolism. Because of their importance in the regulation of substances in the body, when the kidneys stop working properly all the body is influenced by that creating disequilibrium in the maintenance of homeostasis and control of all the metabolic functions which can indirectly cause other problems to the body.... ... middle of paper ... ...
Sobriety is a goal that can compel and frighten. One the one hand, you can probably see at least some of the problems that using caused for you. The idea of fixing even a few of those problems is quite compelling for some. On the other hand, the alcohol or drug permeated your life and social circle. Getting sober means giving up both the substance and all those relationships.
