One of the two kidney bean shaped organs located on both sides of the spine, just above the waist They rid the body of waste materials and maintain fluid balance through the production of urine
—One of two organs that are part of the urinary tract; responsible for filtering the blood and removing waste products and excess water as urine
Oval shape with a concave front (kidney shape), applied to dressing tables, writing tables, etc Appears in 18th Century furniture of England and France Especially favored by Sheraton
Your kidneys are the organs in your body that take waste matter from your blood and send it out of your body as urine
One of the paired organs that excrete urine 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, about opposite the twelfth thoracic and first three lumbar vertebrae
Kidneys are the kidneys of an animal, for example a lamb, calf, or pig, that are eaten as meat. steak and kidney pie. One of a pair of organs that maintain water balance and expel metabolic wastes. Human kidneys are bean-shaped organs about 4 in. (10 cm) long, in the small of the back. They filter the entire 5-quart (about 4.5-liter) water content of the blood every 45 minutes. Glucose, minerals, and needed water are returned to the blood by reabsorption. The remaining fluid and wastes pass into collecting ducts, flowing to the ureter and bladder as urine. Each kidney has over 1 million functional units (nephrons) involved in the process of filtration and reabsorption. The kidneys also secrete renin, an enzyme involved in blood pressure regulation. Disorders include kidney failure, kidney stones, and nephritis. See also urinary system. kidney failure kidney stone kidney transplant
A glandular organ which excretes urea and other waste products from the animal body; a urinary gland
includes urinary and reproductive systems, growth and development, endocrine system, hormones, brain and nervous system, metabolism, bones, hair, and respiratory functions
One of a pair of organs in back of the abdominal cavity which filter waste materials out of the blood and pass them out of the body as urine
The kidney is the main organ of excretion and osmoregulation in vertebrates, through which nitrogenous waste material (principally urine), water, and ions, etc are eliminated from the body In humans there is a pair of kidneys situated in the abdomen, below the diaphragm, on the back
{i} one of a pair of organs that filters metabolic wastes from the blood; temperament; kind, sort, class
Kidneys are a pair of glandular organs in the abdominal cavities of mammals and reptiles Calf's and lamb's kidneys are amongst the most delicate Pig's kidneys are larger and coarser To prepare remove the outer membrane and the central core Usually sautéed or grilled
either of two bean-shaped excretory organs that filter wastes (especially urea) from the blood and excrete them and water in urine; urine passes out of the kidney through ureters to the bladder
The organ that filters water and waste products from the blood and creates urine Most people have two kidneys
- one of two bean-shaped organs located above the waist on either side of the spine Kidneys filter impurities from the blood, maintain the body's fluid balance, and produce urine
large dark red bean; usually dried the common bean plant grown for the beans rather than the pods (especially a variety with large red kidney-shaped beans)
Kidney beans are long, very narrow beans that are green in colour and are eaten as a vegetable. They grow on a tall climbing plant and are the cases that contain the seeds of the plant
Any one of several chronic conditions that are caused by damage to the cells of the kidney People who have had diabetes for a long time may have kidney damage Also called nephropathy
or renal failure Partial or complete loss of kidney function. Acute failure causes reduced urine output and blood chemical imbalance, including uremia. Most patients recover within six weeks. Damage to various kidney structures can result from chemical exposure, major blood loss, crush injury, hypertension, severe burns, severe kidney infections, diabetes mellitus, renal artery or urinary tract blockage, and liver diseases. Complications include heart failure, pulmonary edema, and high potassium levels. Chronic failure usually results from long-term kidney diseases. The blood becomes too acidic, bones can lose calcium, and nerves can degenerate. The kidneys can sustain life until they lose about 90% of their function. If one is removed, the other increases in size and function to compensate. Failure of both usually requires dialysis or kidney transplant
A small hard mass in the kidney that forms from deposits chiefly of phosphates and urates. or renal calculus Mass of minerals and organic matter that may form in a kidney. Urine contains many salts in solution, and low fluid volume or high mineral concentration can cause these salts to precipitate and grow, forming stones. Large stones can block urine flow, be a focus for infection, or cause renal colic (painful spasms). They can obstruct the urinary system at various points. Treatment deals with any underlying problem (e.g., infection or obstruction), tries to dissolve stones with drugs or ultrasound (lithotripsy), or removes large ones surgically
A kidney stone is a hard pebble-like mass commonly composed of calcium oxalate that forms within the kidney Some kidney stones cause pain and must be removed from the body using surgery or ultrasound techniques
Also known as renal calculi, kidney stones are the result of crystallization of certain substances found in urine, including calcium, phosphate, oxalic acid, and uric acid Stones may form in the urine collecting area (pelvis) of the kidney, as well as the ureters (narrow tubes connecting the kidney to the urinary bladder)
or renal transplant Replacement of a diseased or damaged kidney with one from a living relative or a legally dead donor. The former's tissue type is more likely to match, reducing the chance of rejection; but removal puts the donor at risk, and a kidney from a dead donor is more likely to be available. The new kidney is implanted and its blood vessels and ureter sewn in place. A near-normal life may be resumed within two months, but the drugs that prevent rejection leave the patient vulnerable to infection. See also transplant
Two organs in the lower back that clean waste and poisons from the blood The kidneys are shaped like two large beans and they act as the body's filter They also control the level of some chemicals in the blood such as sodium, potassium and phosphate Kidneys also control blood pressure and regulate red blood cell production
A pair of organs that maintain proper water and electrolyte balance, regulate acid-base concentration, and filter the blood of metabolic waste, which is excreted as urine Kidneys can be donated and transplanted
the two bean-shaped organs that filter wastes from the blood and form urine The kidneys are located near the middle of the back They send urine to the bladder
(KID-neez): A pair of organs in the abdomen that remove waste from the blood (as urine), produce erythropoietin and are responsible for the long-term regulation of blood pressure
The two bean-shaped body organs where urine is made They are located at the back of the body, below the ribs The two main functions of the kidneys are to remove toxic wastes and to remove excess water from the body The kidneys also help to control blood pressure, help to control the manufacture of red blood cells and help to keep the bones strong and healthy
Two organs in the lower back that clean waste and poisons from the blood The kidneys are shaped like two large beans, and they act as the body's filter They also control the level of some chemicals in the blood such as hydrogen, sodium, potassium, and phosphate
() From Middle English kednei, kidenei, from earlier kidnēre, kidenēre (“kidney”). Of uncertain origin. Probably a compound consisting of Middle English *kid-, *quid- (“belly, womb”), from Old English cwiþ, cwiþa (“belly, womb, stomach”) + Middle English nēre (“kidney”), from Old English *nēore (“kidney”), from Proto-Germanic *ni(g)wran, *ni(g)wrian (“kidney”), from Proto-Indo-European *negʷh-r- (“kidney”). If so, then related to Dutch nier (“kidney”), German Niere (“kidney”), Danish nyre (“kidney”). Alternate etymology traces the first element to Old English cēod, codd (“sack, scrotum”), as the terms for testicle and kidney were often interchangeable in Germanic (compare Old High German nioro (“kidney", also "testicle”), Old Swedish vig-niauri (“testicle”).
