"femoral vein"的定义和意义

What is a "femoral vein"?

The femoral vein is a major vein located in the thigh region of the human body. It begins at the level of the groin and travels parallel to the femoral artery. The femoral vein collects deoxygenated blood from the deep veins of the thigh and lower leg, including the popliteal vein, and carries it toward the heart. It plays a crucial role in venous circulation, facilitating the return of blood back to the heart for oxygenation and nutrient replenishment. The femoral vein is an important access point for medical procedures such as venous catheterization and blood sampling.
