The great saphenous vein drains into which of the following vessels?

The great saphenous vein drains directly into the femoral vein, which is a crucial point in understanding venous anatomy within the lower extremity. The great saphenous vein is the longest vein in the body and runs along the length of the leg, eventually connecting to the femoral vein at the groin area, specifically at the saphenofemoral junction. This connection is significant because it is the primary pathway for venous return from the superficial venous system of the leg to the deep venous system, which is essential for efficient blood circulation.

The other options do not accurately represent the drainage pathway of the great saphenous vein. For example, while the popliteal vein is an important vessel at the back of the knee, it receives blood from the anterior and posterior tibial veins, rather than the great saphenous vein. The fibular vein, also known as the peroneal vein, primarily drains the posterior compartment of the leg into the posterior tibial veins and does not connect with the great saphenous vein. Lastly, the small saphenous vein, which runs along the back of the leg, drains into the popliteal vein, making it unrelated to the
