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.

Formation of urine is a process important for the whole organism. Not only acid-base balance is modulated by it, but also blood osmolarity, plasma composition and fluid volume, and thus it influences all cells in our body. A healthy adult person produces 1.5-2 liters of urine per day and this process involves three basic mechanisms: 1) Glomerular filtration. 2) Tubular reabsorption. 3) Tubular secretion. Functional anatomy. The basic functional unit for the urine formation is called nephron. Very important is the arrangement of nephron: it begins with renal corpuscle (Malpighi) that consists of a glomerulus, which is supplied by afferent glomerular arteriole and drained by efferent glomerular arteriole, and Bowmanâs capsule (capsula glomeruli, glomerular capsule).
