The connections of lymphatic vessels draining female reproductive organs with lymphnodes in the pig.
The connections of lymphatic vessels leaving the reproductive organs (ovary, oviduct, uterine horn, corpus and cervix, and vagina) with lymphnodes (normal and hemal) located in the uterine broad ligament and paraaortal regions were examined in the cyclic and immature pigs. To visualize the lymph pathways, the lymphatic lumen was filling with varicoloured microfil and/or ink-gelatin mass introduced all the way down to appearance in several nodes. This study revealed that lymphatics emanating from the uterine horn, corpus and the anterior part of the cervix demarcated large a lymphatic area in the porcine broad ligament. From the caudal portion of the cervix and vagina 2-3 lymphatics were found to emerge running near walls of these organs and connecting with large complex nodes, and 2-3 lymphatics reaching the plica urogenitalis. Generally, the lymphatic vessels leaving the porcine reproductive organs were connected by collector lymphangions with 3-5 normal-, 0-3 hemal- and one large composed nodes all found between the distal vascular subovarian plexus and the uterine artery as well as with 9-27 normal and 3-9 hemal nodes in the paraaortal region.
