And you [B] LACK sense, instead of giving me an answer you give me the run around. what function does the leg add that is neccessary for performance of the systems you named? [/B]
The leg's femoral artery is part of the circulatory system. The femur and the soleus contribute to the musculoskeletal system. The golgi tendon organs and muscle spindles in the leg contribute to the somatosensory system which is part of the wider nervous system. Remove the leg components and these systems all still function, however that does not mean that they are not part of the function of the systems.
You clearly know nothing about human anatomy. Stop trying to insist on a false dichotomy because these systems do not agree with your belief in some ad hoc definition. If you're not going to read and comprehend what people say then stop wasting people's time. And go and do something productive like looking for ribosomes in mature mammalian erythrocytes.
