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.

Urine Formation. Urine is formed through a combination of four basic processes: 1) glomerular filtration, 2) tubular reabsorption, 3) tubular secretion, and 4) water conservation. Blood is under high pressure in the glomerulus; thus, plasma (except for plasma proteins) moves into the glomerular capsule.rineis formed through a combination of four basic processes: 1) glomerular filtration, 2) tubular reabsorption, 3) tubular secretion, and 4) water conservation. Blood is under high pressure in the glomerulus; thus, plasma (except for plasma proteins) moves into the glomerular capsule. This fluid is called filtrate.
