Ko te hononga arotahi/whakanui hauora he taputapu e whakamahia ana i roto i te ao rongoā hei whakarei ake i te tirohanga i roto i ngā tikanga hauora, inā koa i roto i te endoscopy me te microscopy. Kua hangaia hei hono i waenga i te pūnaha whakaahua hauora me te taputapu whatu, pēnei i te endoscope, te microscope rānei, kia taea ai te whakanui me te arotahi. Ka taea e te hononga te whakamahi i ngā taumata whakanui rerekē, ka taea ai e ngā tohunga hauora te whakarite i te taumata whakanui kia tino tirotirohia me te tātari i te rohe ūnga. Ka taea hoki te arotahi tika, kia pai ai te kounga me te mārama o te ahua i roto i te tikanga. Ko te tikanga he taputapu whatu kounga teitei kei roto i te taputapu, kia kore ai he hapa me te taumira teitei. He taputapu nui te hononga arotahi/whakanui i roto i ngā tautuhinga hauora, nā te mea ka āwhina i te tautuhi tika, ngā tikanga pokanga whai hua, me te tirohanga pai mō ngā kaimahi hauora. Mā ōna āheinga whakanui me te arotahi ka taea te whakarite, ka whakarei ake i te tika me te whai hua o ngā tikanga hauora, ka pai ake ngā putanga mō ngā tūroro.
