What's the difference between a femur and tibia?
assistant
The main difference between a femur and tibia is that they are two different bones in the leg. The femur is the longest bone in the body, running from the hip to the knee joint. It provides structural support for the body and allows us to walk upright. The tibia is located below the femur and runs from the knee joint down to the ankle. It helps to absorb shock during walking.
