The uterine venous plexus is a network of veins located around the uterus. It plays a crucial role in draining blood from the uterus and surrounding structures. This plexus is connected to other venous systems, including the ovarian veins and the internal iliac veins, facilitating efficient blood flow. This venous network is important during pregnancy, as it helps accommodate increased blood volume and pressure. The uterine venous plexus also contributes to the regulation of blood flow during the menstrual cycle, ensuring that the uterus receives adequate oxygen and nutrients for its functions.
