Physiology of female reproductive tract: venoarterial passage

 

Ovarian veins drain into the inferior vena cava on the right) and left renal vein on the left. The two veins anastomose at the mesosalpinx. The rule is for vein and artery to be in contact so much that materials can diffuse from one to another in the process known as venoarterial passage. This influences the circulation, making it a closed one, and a functional portal system, since venous blood coming from the ovary, which contains large amounts of hormones would have diffused its hormones into the arteries that supply the organs  along the mesosalpinx and later on the sides of the vagina and the cervix. There is a longitudinal anastomoses from the ovarian vein or artery superiorly at the level of the ovary to the azygos vein or artery of the vagina below, which is a tributary (or branch) of internal pudendal vein. The vessels, which take part in this anastomoses are as follows
