Also called statute mile. a unit of distance on land in English-speaking countries equal to 5280 feet, or 1760 yards (1.609 kilometers).
Urine formation begins in the renal corpuscle, where blood passing through the glomerulus is filtered. Filtrates include water, ions, and other solutes, which are filtered out of the blood and into the capsular space to begin urine formation. Urine passes into the proximal convoluted tubule, then into the nephron loop.The nephron concentrates urine by the process of the countercurrent multiplication system.iltrates include water, ions, and other solutes, which are filtered out of the blood and into the capsular space to begin urine formation.

Basically, the process of urine formation takes place in three (3) stages, as blood plasma flows through the nephrons. Nephrons are microscopic tube-like structures in the kidneys that filter the blood and cause wastes to be removed. As the fluid moves through the renal tubule it is called tubular fluid. 2  It is different form glomerular filtrate because of substances which are removed and added by the tubule cells. 3  Finally, when the fluid moves into the. 4  it is called urine.
