What Is the Role of the Kidney in Homeostasis?
Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium —in your blood. Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption. This process is necessary to maintain a stable balance of body chemicals.
One of the most effective ways to keep an eye on your kidneys performance is by understanding your kidney health and function. From the filtering of waste products to the water balance in the body - the kidneys perform many crucial functions. Some of the kidneys key functions include:. The kidneys filter out toxins, excess salt, urea, and waste products by flushing them out of rolr body with urine. It does this by releasing excess sodium in urine and by actively retaining or releasing water out of the body.
If blood pressure is low, the kidneys produce a protein called angiotensin and a hormone called renin - both work together to constrict the vessels and bring your blood pressure to a more stabilised level. The kidneys regulate red blood cells by producing a hormone called erythropoietin EPO. In response to increased acidity in the body, the kidneys attempt to secrete more hydrogen and generate more bicarbonate to regulate the body's acidity levels and ensure PH levels are balanced.
When it comes to finding out more about your kidneys performance - a blood or urine test is usually the go to. The test commonly tests kidnfys eGFR estimated glomerular filtration rate ; this is a simple calculation to determine how well your kidneys are filtering blood. If the glomerular filtration rate GFR is low, kidneyx may indicate that the kidneys are not working as they should. According to the National Kidney Foundation, a normal glomerular filtration rate in adults is above 90, though this 'normal' rate may differ based on age.
It's important to note that a low GFR may tue kidney disease but early detection and treatment may help the kidney disease worsening. In simple terms, kidney disease means your kidneys have become damaged and can no longer perform their key functions properly. Chronic kidney disease is a long-term condition which can get worse over time, sometimes developing into chronic kidney failure. Acute kidney disease develops rapidly and tends to be more common in those who are already critically ill and hospitalized.
Sometimes acute kidney failure may not cause any symptoms. Chronic kidney disease mainly occurs as a result of a disease or condition which impairs kidney function which damages the kidneys function over a period of time. If you simply want to know a bit more about your kidney health, you have fo option to take a kidney function test from the comfort of your own home.

What is normal kidney function?
May 22, · What are kidneys? The kidneys are two bean-shaped organs in the renal system. They help the body pass waste as urine. They also help filter blood before sending it back to the heart. What is the Function of Our Kidneys? The kidneys are a very important organ in the body. They are two bean-shaped organs, each about the size of a fist, located just below the rib cage, one on each side of your spine. The kidneys are responsible for getting rid of waste products, drugs, and toxins through our urine. The kidneys are essential for homeostasis (maintaining a constant internal environment) of the body's extracellular fluids. 1. Regulation of extracellular fluid volume. blood flowing to vital organs.
The kidneys play several important roles in maintaining homeostasis, including maintaining the proper blood volume and ion balance as well as removing nitrogenous wastes from the blood. The kidney primarily accomplishes these tasks by filtering impurities, metabolic wastes and salt from the blood.
According to the BBC, the kidneys are able to maintain homeostasis in part by varying the concentration of urine. For example, when the amount of water in the blood plasma is low, the kidneys reabsorb water from the urine, returning it to the blood stream. Conversely, when the amount of water in the blood plasma is high, the kidneys do not reabsorb much water, which produces highly dilute urine.
Both responses help to keep the body's water balance within the range of tolerance. The kidneys must compensate for other biological functions and stimuli that may alter the water balance of the body, thus disrupting homeostasis. The BBC lists several such stimuli, including the external temperature, exercise and salt intake, as having the potential to change the amount of water in the body.
For example, during exercise, the body's temperature rises. The body attempts to compensate for this by sweating. However, sweat results in a net loss of water, which in turn, triggers the kidneys to reabsorb more water from the urine and return it to the bloodstream.
