Which statement about the GSV is FALSE?

The statement that is identified as false is that the great saphenous vein (GSV) has more valves in the calf than in the thigh. In fact, the GSV generally contains a greater number of valves in the thigh than in the calf. This anatomical structure's arrangement helps facilitate the upward flow of blood towards the heart, counteracting the effects of gravity, especially in the lower extremities.

Understanding the other statements provides valuable context. The GSV does indeed pass superiorly on the medial side of the thigh and extends distally to the dorsum of the foot, which are accurate characteristics of this vein's anatomy. Additionally, it enters the femoral vein, making it a significant vessel for venous drainage from the lower limb into the systemic circulation.
