Editing Prostate (section)

===Blood and lymphatic vessels===
The prostate receives blood through the [[inferior vesical artery]], [[internal pudendal artery]], and [[middle rectal arteries]]. These vessels enter the prostate on its outer {{wt|en|posterior}} surface where it meets the bladder, and travel forward to the apex of the prostate.<ref name="Standring-2016" /> Both the inferior vesical and the middle rectal arteries often arise together directly from the [[internal iliac arteries]]. On entering the bladder, the inferior vesical artery splits into a urethral branch, supplying the urethral prostate; and a capsular branch, which travels around the capsule and has smaller branches, which perforate into the prostate.<ref name="Standring-2016" />

The veins of the prostate form a network – the [[prostatic venous plexus]], primarily around its front and outer surface.<ref name="Standring-2016" /> This network also receives blood from the [[deep dorsal vein of the penis]], and is connected via branches to the [[Vesical venous plexus|vesical plexus]] and [[internal pudendal veins]].<ref name="Standring-2016" /> Veins drain into the [[Vesical veins|vesical]] and then [[internal iliac vein]]s.<ref name="Standring-2016" />

The lymphatic drainage of the prostate depends on the positioning of the area. Vessels surrounding the [[vas deferens]], some of the vessels in the seminal vesicle, and a vessel from the posterior surface of the prostate drain into the [[external iliac lymph nodes]].<ref name="Standring-2016" /> Some of the seminal vesicle vessels, prostatic vessels, and vessels from the anterior prostate drain into [[internal iliac lymph nodes]].<ref name="Standring-2016" /> Vessels of the prostate itself also drain into the [[Obturator lymph nodes|obturator]] and [[sacral lymph nodes]].<ref name="Standring-2016" />
