The inferior vesical arteries ramify over the fundus and neck of the bladder. On their way to the bladder, the arteries pass through the lateral ligaments of the bladder, where they usually give off ureteric branches and (in the male) branches to the seminal glands (vesicles) and prostate. In males, the inferior vesical arteries may give rise to the deferential arteries.

In some, the bladder receives additional branches from the obturator, inferior gluteal, or internal pudendal arteries.

Vesical veins are short, uniting into a rich vesical venous plexus around the base of the bladder. In males, this plexus is continuous with the prostatic venous plexus.

The vesical plexus (or prostatic plexus in males) communicates with the veins of the perineum, receiving the dorsal vein of the clitoris (or penis). Multiple interconnecting channels lead from the plexus to the internal iliac veins. Anastomoses with the parietal veins of the pelvis establish connections to the internal vertebral venous plexus, thighs, and gluteal regions.
