Final answer:
The Superficial Femoral Artery (SFA) becomes the popliteal artery as it crosses behind the knee, which then branches into the anterior and posterior tibial arteries.
Step-by-step explanation:
As the SFA (Superficial Femoral Artery) crosses behind the knee, it becomes the popliteal artery. The femoral artery itself is a continuation of the external iliac artery after it passes through the body cavity and it divides into several smaller branches before becoming the popliteal artery as it passes posterior to the knee. The popliteal artery then divides into the anterior and posterior tibial arteries.
