Blood supply of the male pelvis (Latin)

At the level of the articulatio sacroiliaca, the bilateral a. iliaca communis bifurcates into the a. iliaca interna and a. iliaca externa. The a. iliaca externa courses towards the thigh to continue as the a. femoralis, whereas the a. iliaca interna courses towards the foramen ischiadicum majus and gives off multiple branches to supply the pelvic wall and organs. These can be divided into a divisio anterior and posterior. Branches of the divisio posterior are the a. iliolumbalis, a. glutea superior and a. sacralis lateralis. The divisio anterior gives off the a. obturatoria, a. umbilicalis, aa. vesicales superior et inferior, a. pudenda interna and a. anorectalis media. The veins of the male pelvis collect blood from the urogenital organs and the rectum and drain into the v. iliaca interna (or v. mesenterica inferior in the case of the v. [ano]rectalis superior). From the v. iliaca interna, the blood is transported to the v. iliaca communis and from there into the v. cava inferior. The vv. testiculares dextra/sinistra directly drain directly to the v. cava inferior and v. renalis sinistra, respectively.
