    Fuji,
    Physiology respiration refers to what parts of the body are involved in the respiration itself as breathing is the general English term or word used for respiration. I hope I answered your question.

    It's the same. Breathing is used in layman's term or common word but if you use the word Physiology it is already scientific natured.

    For the 4th question answer, must the answer be pertaining to respiration? Or not?

    Fuji,

    Are you referring about the 4th question? About smoking? It's ok if it does not refer to the respiration. Just present in the effects of smoking in the body.
