SFA Full Form in Medical term is Superficial Femoral Artery. And femoral Artery is the primary blood vessel carrying blood to your lower body. It starts in your upper thigh, near your groin, and goes down to the back of your knee. The FA’s role is to pass blood to the lower body. To get nutrients and oxygen, your tissues need blood.
Human tissues require blood to receive nutrients and oxygen. The femoral artery carries oxygen-rich blood away from your heart like other arteries. This vein transmits deoxygenated blood from the lower part of your body back to your heart.
The superficial Femoral Artery is one of the branches of the femoral Artery. This continues from the common femoral Artery. It imparts blood to the lower part, especially the leg, including the muscles at the front part of your knee and thigh.
Branches of the FA, including the superficial femoral Artery, are the designation for the segment between the branch point of the deep femoral Artery and the adductor hiatus, which convey through the sub-sartorial canal. However, using SF is discouraged by various practitioners as it confuses regular practitioners.
