1. kidneys

   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".

2. Bob Watson:

   Both my kids offered to donate kidneys to me, and I told them both the same thing : ‘ I’ve had a good life and I don’t want to take a kidney from young people who really need them and still have their whole lives ahead of them.' That would be very selfish on my part.

3. Tonya Saffer:

   If you give a 20-year-old a 65-year-old kidney, there is a likelihood the 20-year-old will have to get another transplant at some point. So this fixes that, we will be able to make better use of kidneys and not have to re-transplant as many people.

4. Peter Navarro:

   We know statistically, based on our experience with the China trade shock in the 2000s, that unemployment creates more suicides, depression and drug abuse, but we also know this in this crisis, as we've basically locked down our hospitals for everything but Covid, women haven't been getting mammograms or cervical examinations for cancer. We haven't been able to do other procedures for the heart or the kidneys. And that's going to kill people as well.

5. Ivan Koedjikov:

   Most of the trafficking of kidneys and other organs in the world flows from poor to rich countries, and within poor countries, from poor to rich people, in most cases it's the most vulnerable who give.
