Icandelo leTrachea

Le nto yenziwe ziimodeli ezi-3 ezahlukeneyo kwisiseko esinye: eyokuqala ivelisa kwakhona i-3X yobungakanani bobunqamle beqhekeza lomntu; ingahlulwa kubude obude ibe ngamacandelo amabini ukubonisa i-anatomy yangaphakathi. Imodeli yesibini kukwandiswa kwecandelo lodonga olunqamlezileyo lwangaphambili; ibonisa onke amanqwanqwa ahlukeneyo, ukusuka kwi-tracheal cartilage ukuya kwi-epithelium. Owesithathu ubonakalisa i-epsehelium edityanisiweyo ye-epithelium eneenkcukacha ezinkulu: ibonisa iiseli ze-ciliated zeseli kunye neeseli ezinomqolo.
