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.
6. Identify the lymphatic drainage of structures of the
pelvis and perienum.
Rules:
Para-aortic
•
External iliac
•
Superficial Inguinal
Internal iliac
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

reproductive tract and the pathway taken by a spermatozoon
through the male reproductive tract.
