It is composed of renal cortex containing the renal glomerules and the medulla that consists of renal pyramids. The peaks of these pyramids are surrounded by small renal calyxes which combine to form large renal calyxes and these finally constitute the renal pelvis. At the renal orifice, the pelvis merges with the urether without a clear demarcation line. Arterial blood is led to the kidney by the renal artery, which is a paired branch of the abdominal aorta and branches of perpendicularly, at the level of the second lumbar vertebra. The renal artery and its branches provide for the renal functional and nutritive blood flowLedvica je paren organ, ki leži na lumbokostalnem trikotniku trebušne prepone in na mišicah zadnje trebušne stene izven peritonealne votline. Obdaja jo vezivna in maščobna ovojnica. Zgrajena je iz ledvične skorje v kateri se nahajajo ledvični glomeruli in iz ledvične sredice, ki jo oblikujejo ledvične piramide. Vrhove piramid obdajajo male ledvične čašice, ki se združujejo v velike ledvične čašice, te pa v ledvični meh. V ledvični lini ledvični meh brez ostre meje preide v sečevod. Arterijsko kri vodi v ledvico ledvična arterija, ki je parna veja trebušne aorte in se od nje odcepi pravokotno v višini drugega ledvenega vretenca. Arterija s svojimi vejami predstavlja hkrati funkcionalni in nutritivni krvni obtok ledviceTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo Medicinski razgledi
