Samuel Johnson's Dictionary

  1. KIDNEYnoun

    1.These are two in number, one on each side: they have the same figure as kidneybeans: their length is four or five fingers, their breadth three, and their thickness two: the right is under the liver, and the left under the spleen. The use of the kidneys is to separate the urine from the blood, which, by the motion of the heart and arteries, is thrust into the emulgent branches, which carry it to the little glands, by which the serosity being separated, is received by the orifice of the little tubes, which go from the glands to the pelvis, and from thence it runs by the ureters into the bladder. John Quincy

    Etymology: Etymology unknown.

    A youth laboured under a complication of diseases, from his mesentery and kidneys. Richard Wiseman, Surgery.

    Think of that, a man of my kidney; think of that, that am as subject to heat as butter; a man of continual dissolution and thaw. William Shakespeare, Merry Wives of Windsor.

    There are millions in the world of this man’s kidney, that take up the same resolution without noise. Roger L'Estrange.

  1. Kidney

    The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (4+1⁄2 inches) in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains only about 12,500 nephrons. The kidneys also carry out functions independent of the nephrons. For example, they convert a precursor of vitamin D to its active form, calcitriol; and synthesize the hormones erythropoietin and renin. Chronic kidney disease (CKD) has been recognized as a leading public health problem worldwide. The global estimated prevalence of CKD is 13.4%, and patients with kidney failure needing renal replacement therapy are estimated between 5 and 7 million. Procedures used in the management of kidney disease include chemical and microscopic examination of the urine (urinalysis), measurement of kidney function by calculating the estimated glomerular filtration rate (eGFR) using the serum creatinine; and kidney biopsy and CT scan to evaluate for abnormal anatomy. Dialysis and kidney transplantation are used to treat kidney failure; one (or both sequentially) of these are almost always used when renal function drops below 15%. Nephrectomy is frequently used to cure renal cell carcinoma. Renal physiology is the study of kidney function. Nephrology is the medical specialty which addresses diseases of kidney function: these include CKD, nephritic and nephrotic syndromes, acute kidney injury, and pyelonephritis. Urology addresses diseases of kidney (and urinary tract) anatomy: these include cancer, renal cysts, kidney stones and ureteral stones, and urinary tract obstruction. The word “renal” is an adjective meaning “relating to the kidneys”, and its roots are French or late Latin. Whereas according to some opinions, "renal" should be replaced with "kidney" in scientific writings such as "kidney artery", other experts have advocated preserving the use of renal as appropriate including in "renal artery".

  1. kidney

    A kidney is an organ in the body that is part of the urinary system with the primary function of filtering waste products, toxins, and excess substances like water or electrolytes from the bloodstream. These waste products are then converted into urine and excreted from the body. Humans have two kidneys, located on either side of the spine, just below the rib cage. The kidneys also help to regulate blood pressure, maintain body self-acidity level and produce certain hormones.

Webster Dictionary

  1. Kidneynoun

    a glandular organ which excretes urea and other waste products from the animal body; a urinary gland

  2. Kidneynoun

  1. Kidney

    The kidneys are organs that serve several essential regulatory roles in most animals, including vertebrates and some invertebrates. They are essential in the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure. They serve the body as a natural filter of the blood, and remove wastes which are diverted to the urinary bladder. In producing urine, the kidneys excrete wastes such as urea and ammonium, and they are also responsible for the reabsorption of water, glucose, and amino acids. The kidneys also produce hormones including calcitriol, erythropoietin, and the enzyme renin. Located at the rear of the abdominal cavity in the retroperitoneum, the kidneys receive blood from the paired renal arteries, and drain into the paired renal veins. Each kidney excretes urine into a ureter, itself a paired structure that empties into the urinary bladder. Renal physiology is the study of kidney function, while nephrology is the medical specialty concerned with kidney diseases. Diseases of the kidney are diverse, but individuals with kidney disease frequently display characteristic clinical features. Common clinical conditions involving the kidney include the nephritic and nephrotic syndromes, renal cysts, acute kidney injury, chronic kidney disease, urinary tract infection, nephrolithiasis, and urinary tract obstruction. Various cancers of the kidney exist; the most common adult renal cancer is renal cell carcinoma. Cancers, cysts, and some other renal conditions can be managed with removal of the kidney, or nephrectomy. When renal function, measured by glomerular filtration rate, is persistently poor, dialysis and kidney transplantation may be treatment options. Although they are not severely harmful, kidney stones can be painful and a nuisance. The removal of kidney stones involves ultrasound treatment to break up the stones into smaller pieces, which are then passed through the urinary tract. One common symptom of kidney stones is a sharp pain in the medial/lateral segments of the lower back.

    I would think that the majority of marathon runners are doing OK because the 22 people who participated in the study had normal kidney function and had been running marathons for an average of 12 years, so, if running marathons caused a great deal of permanent kidney injury, these runners would have minimal kidney function remaining.
