What happens if femoral artery is blocked?
The arteries in your legs and feet can get blocked, just like the arteries in your heart. When this happens, less blood flows to your legs. This is called peripheral artery disease (PAD). If your leg arteries are badly blocked, you may develop foot pain while resting or a sore that won't heal.
Where are the arteries in your thigh?
The femoral artery is a major artery and blood supplier to the lower limbs of the body. The artery stems from the iliac artery, which is located in the pelvis. The femoral artery starts in the lower abdomen and goes through the thigh, which is how blood is circulated through the legs.
What is the artery that supplies the anterior thigh muscles?
