What is the longest bone in the human body?

The femur, or thigh bone, is the longest and strongest bone, connecting the hip to the knee and supporting body weight. Studying this highlights its role in human anatomy, the challenges of understanding skeletal functions, and its impact on mobility. For Pakistan, this offers lessons on improving medical education, enhancing orthopedic care, and raising public health awareness about bone health to address issues like osteoporosis in aging populations.
