The femur is part of the skeletal system. The skeletal system contains all the bones in the body, which is about 260 bones for infants and around 206.
Similarly, you may ask, why is the femur the strongest bone in the body?
The thigh bone is the strongest, heaviest, and longest bone in our body. It is a major part of the appendicular skeleton and it's strongest bone in our body because it holds up all of your body weight during any activity except sitting.
Beside above, why is the femur hollow? It is evident that the hollow shaft provides efficiently for resisting bending moment not only due to the load on the femur-head, but from any other loads tending to produce bending in other planes.
Subsequently, one may also ask, how does the femur work?
The femur is the longest bone in the human skeleton. It functions in supporting the weight of the body and allowing motion of the leg. The femur articulates proximally with the acetabulum of the pelvis forming the hip joint, and distally with the tibia and patella to form the knee joint.
Where is the femur bone located in the body?
Location. The femur is located, as the common term for it suggests, in the thigh or upper portion of the leg and it runs from the hip to the knee. The proximal end of the bone, the part that is located closest to the hip, has the femoral head that helps to create the joint within the hip.

Function. As the femur is the only bone in the thigh, it serves as an attachment point for all the muscles that exert their force over the hip and knee joints. Some biarticular muscles – which cross two joints, like the gastrocnemius and plantaris muscles – also originate from the femur.What does the scapula do?
The scapula is commonly referred to as the shoulder blade. It connects the humerus bone of the arm to the collarbone.
