Follow the flow of blood into an out of the structures of the pelvis and perineum. Rules: 1. All pelvic organs are supplied by branches of the internal iliac artery except the ovaries and the upper third of the rectum. 2. Venous drainage follows the arterial supply, including the portal tributary, the inferior mesenteric vein. 3. Portal caval anastomses are found at the inferior rectal veins.

9. Para-aortic External iliac Superficial Inguinal Internal iliac 6. Identify the lymphatic drainage of structures of the pelvis and perienum. • Rules: • Lymphatics drain toward lymph nodes along internal iliac veins, except for the ovary (para-aortic nodes), and superior portion of the rectum (inferior mesenteric nodes) • Perineum drains to superficial inguinal nodes
