Give a stream of consciousness and then the final answer. Passage: The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have wider pelvic bones, causing their femora to converge more than in males. In the condition genu valgum (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is genu varum (bow-leggedness). In the general population of people without either genu valgum or genu varum, the femoral-tibial angle is about 175 degrees.\n\nQuestion: Based on this passage, where is the femur located in your body?

This is the relevant information: The femur is the only bone in the upper leg.
So, the final answer is in the upper leg.
