Final answer:
The correct order of bones from head-to-toe is Humerus, Radius, Femur, Tibia.
Step-by-step explanation:
The correct order of long bones from head-to-toe, considering their locations in the human body, is as follows: Humerus, Radius, Femur, Tibia. The humerus, found in the upper arm, is followed by the radius in the forearm. Moving down to the lower extremities, the femur is the thigh bone situated in the upper leg, and beneath it is the tibia, which forms part of the lower leg. This sequence aligns with the anatomical arrangement of these long bones, providing structural support and facilitating various functions in the upper and lower limbs, contributing to the overall skeletal framework from head to toe.
