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 produced in the kidneys. It flows through tubes called ureters into the bladder. Urine leaves the body through the urethra. The bladder muscle helps you urinate by squeezing to force the urine out. A thin surface layer called the urothelium lines the inside of the bladder. Next is a layer of loose connective tissue called the lamina propria. Covering that tissue is the bladder muscle.
