VASCULAR SUPPLY AND LYMPHATICS
The arterial supply to the vagina is via the uterine and vaginal arteries – both branches of the internal iliac artery.
Venous return is by the vaginal venous plexus, which drains into the internal iliac veins via the uterine vein.
Lymphatic drainage is divided into three sections:
- Superior – drains to external iliac nodes
- Middle – drains to internal iliac ndoes
- Inferior – drains to superficial inguinal lymph nodes.
