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.

The urinary tract begins with the kidneys. The kidneys, one on each side, sit high in the upper abdomen partially underneath the ribcage. They filter the blood to extract excess waste products and fluid to form the urine. Urine, once formed in the kidneys, enters the first part of the urinary drainage system called the renal pelvis. The renal pelvis funnels the urine into the ureter. Urine travels through the ureter, which is a tube on each side, down to the bladder.
