Kidney: [TA] One of the paired organs that excrete urine, remove nitrogenous wastes of metabolism, reclaim important electrolytes and water, contribute to blood pressure control(renin-angiotensin system) and erythropoiesis (via erythropoietin production). The kidneys are bean-shaped organs about 11-cm long, 5-cm wide, and 3-cm thick, lying on either side of the vertebral column, posterior to the peritoneum, opposite the 12th thoracic and 1st-3rd lumbar vertebrae. In animals, the kidney has variable size and location. SYN: ren [TA], nephros. [A.S. cwith, womb, belly, + neere, kidney (L. ren, G. nephros)]

Kidney: One of a pair of organs in the abdomen. Kidneys remove
waste from the blood (as urine), produce erythropoietin (a substance that
stimulates red blood cell production), and play a role in blood pressure
regulation.

Kidney (organ): The kidneys are vital internal organs located in the abdomen. Normally people have two functioning kidneys that form a part of the urinary tract in the genitourinary system. The kidneys have a variety of functions. The primary job of the kidneys is to filter waste products and excess water and salts from the blood. Wastes are then eliminated from the kidney through the ureters into the bladder in the form of urine. The kidneys also help to produce red blood cells, some hormones, and to regulate blood pressure.
Conditions that afflict the kidneys include kidney disease, kidney infections, kidney failure, nephrotic syndrome, kidney stones, urinary tract obstruction, kidney anomalies and pyelonephritis.
Kidney (organ): The kidneys are a pair of bean-shaped organs at the back of the middle abdomen at approximately waist level. They take water from the blood and extract waste products thus producing urine that is stored in the bladder. The tubes between kidneys and the bladder are called ureters.
The kidney is the body's main blood filtration system. It removes waste and dangerous substances from the blood stream and excretes them when you urinate. Damage or failure to the kidney is thus a dangerous situation.
Kidney (organ): Your kidneys are bean-shaped organs, each about the size of your fist. They are located near the middle of your back, just below the rib cage. The kidneys are sophisticated trash collectors. Every day, your kidneys process about 200 quarts of blood to sift out about 2 quarts of waste products and extra water. The waste and extra water become urine, which flows to your bladder through tubes called ureters (YOOR-uh-ters). Your bladder (BLAD-ur) stores urine until you go to the bathroom.

Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, harmful wastes build up in your body, your blood pressure may rise, and your body may retain excess fluid and not make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys. (Source: excerpt from Kidney Failure Choosing a Treatment That's Right for You: NIDDK)

The kidneys are bean-shaped organs about the size of your fists. They are near the middle of the back, just below the rib cage. The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.

The kidneys are two reddish-brown, bean-shaped organs located just above the waist, one on each side of the spine. They are part of the urinary system . Their main function is to filter blood and produce urine to rid the body of waste. As blood flows through the kidneys, they remove waste products and unneeded water. The resulting liquid, urine, collects in the middle of each kidney in an area called the renal pelvis. Urine drains from each kidney through a long tube, the ureter , into the bladder , where it is stored. Urine leaves the body through another tube, called the urethra .
