Final answer:
The left ovarian vein connects to the left renal vein, while the right ovarian vein empties directly into the inferior vena cava.
Step-by-step explanation:
The left ovarian vein, which drains the ovary, does not empty directly into the inferior vena cava like the right ovarian vein; instead, it empties into the left renal vein. In comparison, from the male reproductive organs, the right gonadal vein (testicular vein) empties into the inferior vena cava and the left into the left renal vein. This anatomical difference is important because the inferior vena cava lies primarily to the right of the vertebral column, causing the left renal vein to be longer and therefore, it also receives blood from the left gonadal vein. It's important to note that the hepatic portal system does not include the ovarian veins, as the liver receives blood through the hepatic portal vein from digestive organs. Hence, the correct answer to the venous drainage route for the left ovarian vein is B) Connects to the renal vein.
