1. External iliac lymph nodes: The external iliac lymph nodes receive lymphatic drainage from the bladder, the isthmus of the uterus, and deep inguinal nodes.
2. Internal iliac lymph nodes: The internal iliac lymph nodes receive drainage from the pelvic viscera, the gluteal region, and the deep perineum. They do not receive drainage from the ovaries or uterine tubes.
3. Sacral group: The sacral group is located along the median and lateral sacral arteries, and these nodes receive drainage from the posterior pelvic wall, the rectum, and the isthmus of the uterus.
4. Lower paraaortic nodes: The lower paraaortic nodes communicate with lymphatics from the ovaries and uterine tubes.
