  • Razvoj sečil = The development of the urinary tract
    Petrovič, Danijel, 1963-
    The intermediate mesoderm gives rise to the kidney. Three pairs of kidney makean appearance in succession during development: pronephros, mesonephros and metanephros or permanent kidneys. Permanent ... kidneys develop from metanephric diverticulum (ureteric bud) and metanephric blastema. The uretericbud gives rise to the ureter, renal pelvis, major and minor calyces, and approximately one to three million collecting tubules, whereas the metanephric blasterna gives rise to nephrons. The collecting tubules penetratethe metanephric blastema, and they induce the formation of renal vesicles. Renal vesicles give rise to small tubules, which form nephrons or excretory unit (Bowman's capsule, proximal convoluted tubule, loop of Henle, and distal convoluted tubule). Urogenital sinus gives rise to urinary bladder and the uretra. Ureters are of mesodermal origin, whereas the epithelium of urinary bladder is of endodermal origin.
