The Kidneys are two organs located in the back of the abdomen. The kidneys main function is to regulate blood pressure, produce red blood cell, balance electrolytes, filter the blood, and produce urine which is drained in the ureters to the bladder. According to the national institute of diabeties and digestive and kidney disease (2014), the kidneys are a pair of organs shaped like a bean with a size of a fist. These organs are located below the rib cage, one on each side of the spine. The two kidney filters about 120 to 150 quarts of blood every day in order to produce about 1 to 2 quarts of urine which contain wastes and extra fluids. Once the kidneys lose their function, they progress to a chronic Kidney disease which is a slow, progressive, and irreversible deterioration of the renal function. The kidneys become unable to eliminate waste product from the body and maintain a normal electrolytes level and body fluid. As a result, the patient ends up with end stage renal disease requiring some type of renal replacements therapy or kidney transplant to sustain life. Diabetic and hypertension and the most leading cause of chronic kidney disease.
The kidneys usually learn how to adapt and they increase their remaining tissues performance when some

For patients with chronic kidney disease, they are unable to remove excess potassium from the blood which can cause irregular heartbeat, weakness, and heart failure. These patients need to stay away from slat substitute which contain potassium. According to the National Institute of Diabetes and Digestive and Kidney Disease (2013), CKD patients can eat white rice, white bread and pasta, cooked rice, and rice mil instead of brown rice, whole wheat bread and pasta, bran cereal, and cow milk. In addition, banana, cantaloupe, oranges, spinach, tomatoes, potatoes, and avocadoes contain a very high amount of
Kidneys have important roles in maintaining health and making our lives easier everyday. It is located near the middle of your back, just below the rib cage. Functions of the kidneys include extracting wastes from the blood and balancing body fluids from the urine. Most of kidney diseases attack the nephrons, which is the functional units of the kidney. This damages causes kidney malfunctions for example, medicines, genetic problems and injuries.
A few nutrients that I can add to my diet are: potassium, vitamin D, Dietary Fiber, and calcium. I can gain potassium by eating bananas. Potassium helps with heart function, as well as smooth and skeletal muscle contractions. By in taking lima beans, peas, or broccoli I will be able to make sure that my body receives dietary fiber. Fiber helps with
Urinary Tract Infection, also known as UTI, occurs in two common locations, the bladder and kidneys. The kidneys are important organs that aid in filtering out waste products from blood and maintaining water distribution throughout the body. The waste products are filtered out via bladder, which is the reason of the bladder being the second site for the infection. A normal human being has two kidneys, one on left and right side, a bean shaped organ, and is located at the back of the abdomen. “Each kidney is about 11.5 cm long, 5-7.5 cm broad, 5 cm thick, and weight about 150 grams” (HealthInfoNet, Paragraph 2). Furthermore, a bacterium named Escherichia coli lives in both the kidneys and the GI tract. E. coli is part of the human body and produces
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.
In 1954, the first organ transplant was conducted successfully in the United States. (Clemmons, 2009) Nowadays, the technology of organ transplant has greatly advanced and operations are carried out every day around the world. According to current system, organ sales are strictly prohibited in the United States. (Clemmons, 2009) However, the donor waiting list in the United States has doubled in the last decade and the average waiting time for a kidney is also increasing. (Clemmons, 2009) In the year 2007, over 70,000 patients were on the waiting list for a kidney and nearly 4500 of them died during the waiting period. In contrast to the increasing demand for kidney, organ donation has been in a decrease. (Wolfe, Merion, Roys, & Port, 2009) Even the government puts in great effot to increase donation incentives, the gap between supply and demand of organs still widens. In addition, the technology of therapeutic cloning is still not mature and many obstacles are met by scientists. (Clemmons, 2009) Hence, it is clear that a government regulated kidney market with clear legislation and quality control is the best solution to solve the kidney shortage problem since it improves the lives of both vendors and patients.
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.
Chronic kidney disease (CKD), which involves progressive, irreversible loss of kidney function, is present in 26 million Americans (Lewis, 2011, pp 1170-1181). There are many causative factors of CKD. Some of these causes are environmental; that is, the prevalence of CKD is influenced by how we live as individuals. Lack of exercise and poor diet can lead to hypertension, which can lead to CKD. Although other factors are involved, lack of exercise and poor diet also increases a person’s risk for developing diabetes, which is one of the second leading causes of CKD. This paper examines a few of those causes more closely and aims to educate clinicians, and their patients, on health promotion activities that they can implement to reduce the risk of getting CKD.
Kidneys are filter organs present in vertebrates which help in removing water soluble wastes from the blood. A normal human body possesses two kidneys which are bean shaped and weigh around 150 grams each. Kidneys function as the waste disposal system of our body. Every day kidneys are processing around 200 litres of filtrate while absorbing large amount of it and producing around 1 to 2 litres of waste. Kidneys allow reabsorption of molecules from this filtrate into the blood. Thereafter these molecules are transferred to urinary bladder and then expelled from the body as urine. Kidneys are also producing hormones like erythropoietin, vitamin D and enzyme renin. Kidneys perform homeostatic functions which includes regulating
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.
The purpose of this paper is to take an in depth look at a renal diet which is designed for people suffering from certain kidney conditions. A renal diet can be described as a nutritional regime which is: “low in sodium, phosphorous and protein... [It] also promotes the importance of consuming high-quality protein and usually limits fluids. Some patients may also need to limit potassium and even calcium” (Nephcure). Throughout the course of this paper various aspects are addressed. these include: the role of the kidneys, the importance of professional guidance, the reasons why people follow a renal diet, monitoring sodium intake, monitoring potassium intake, monitoring phosphorus intake, protein consumption, and fluid control.
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.
