Urinary System Word Search

Forty words follow water and waste out of the body in this urinary system word search: the two kidneys and the tiny filters inside them, each one a nephron, then the ureter, the bladder and the urethra, with the urea and extra sodium that end up in the urine.

Each kidney holds about a million nephrons. A nephron starts at the glomerulus, a knot of tiny blood vessels that presses water, salts and waste out of the blood. The fluid then runs through a long tubule with a hairpin bend, the loop named for the German anatomist Jakob Henle, and along the way most of the water and nearly all the useful salt and sugar are taken back. When the body is short of water, the pituitary releases vasopressin, which tells the collecting ducts to hold on to more, so the urine comes out darker. Its yellow is a pigment called urochrome, left from old red blood cells.

Urea was one of the first chemicals from a living body to be made in a lab. Friedrich Wohler produced it in 1828 from ammonium cyanate, a salt that had never been part of a plant or animal. Willem Kolff, a Dutch doctor, built a working dialysis machine in 1943 out of sausage casing, tin cans and a washing machine drum. In 1954 Joseph Murray carried out the first lasting kidney transplant in Boston, between identical twins.
