(anatomy) A network of valveless veins in the human body, connecting the deep pelvic veins and thoracic veins (draining the inferior end of the urinary bladder, breast, and prostate) to the internal vertebral venous plexuses.

The rectal venous plexus (or hemorrhoidal plexus) is the venous plexus surrounding the rectum.

The uterine plexuses lie along the sides and superior angles of the uterus between the two layers of the broad ligament, and communicate with the ovarian and vaginal plexuses.

The vesical venous plexus is a venous plexus situated at the fundus of the urinary bladder.

The prostatic veins form a well-marked prostatic plexus which lies partly in the fascial sheath of the prostate and partly between the sheath and the prostatic capsule.
