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 is made when blood is filtered by the kidneys. Urine flows from the kidneys down through the ureters and into the bladder. This one-way flow is usually maintained by a âflap valveâ where the ureter joins the bladder. This keeps urine from backing up into the kidney.
