Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses. Clinical trials look at new ways to prevent, detect, or treat disease. What are clinical trials, and are they right for you?Ĭlinical trials are part of clinical research and at the heart of all medical advances. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and other components of the National Institutes of Health (NIH) conduct and support research into many diseases and conditions. Your ureter carries urine from the kidney to your bladder. Blood flows into your kidneys through the renal artery and exits through the renal vein. Most of the water and other substances that filter through your glomeruli are returned to your blood by the tubules. In a single day, your kidneys filter about 150 quarts of blood. Your blood circulates through your kidneys many times a day.
In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. How does blood flow through my kidneys?īlood flows into your kidney through the renal artery. The remaining fluid and wastes in the tubule become urine. The tubule helps remove excess acid from the blood. As the filtered fluid moves along the tubule, the blood vessel reabsorbs almost all of the water, along with minerals and nutrients your body needs. The tubule returns needed substances to your blood and removes wastesĪ blood vessel runs alongside the tubule. Larger molecules, such as proteins and blood cells, stay in the blood vessel. The thin walls of the glomerulus allow smaller molecules, wastes, and fluid-mostly water-to pass into the tubule. The glomerulus filters your bloodĪs blood flows into each nephron, it enters a cluster of tiny blood vessels-the glomerulus. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.
Each nephron includes a filter, called the glomerulus, and a tubule. How do my kidneys work?Įach of your kidneys is made up of about a million filtering units called nephrons. Your kidneys also make hormones that help Without this balance, nerves, muscles, and other tissues in your body may not work normally. 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. Your kidneys remove wastes and extra fluid from your body. You have two kidneys that filter your blood, removing wastes and extra water to make urine. Your kidneys, ureters, and bladder are part of your urinary tract. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. They are located just below the rib cage, one on each side of your spine. The kidneys are two bean-shaped organs, each about the size of a fist.
