Njira Yogwirira Ntchito

Mtundu wachilengedwe umawonetsa kugaya kokwanira kuchokera pakamwa mpaka kubwerera. Pakamwa pakamwa, pharynx ndi thirakiti yoyamba yam'mimbayo imagawidwa motsatira ndege ya sagittal. Chiwindi chikuwonetsedwa limodzi ndi chikhodzodzo cha ndulu ndipo kapamba amapasidwa kuti awulule zamkati. Mimba ndi yotseguka motsatira ndege yakutsogolo, duodenum, cecum, gawo la matumbo a samll ndi rectum ndi otseguka kuti awulule mawonekedwe amkati. Colon yopingasa ndiyotheka

Njira yogaya imakhala ndi magawo awiri: kagayidwe kake kakudya ndi gland yam'mimba. Kugaya kwam'mimba: kuphatikiza mkamwa, pharynx, kum'mero, m'mimba, m'matumbo ang'ono (duodenum, jejunum, ileum) ndi matumbo akulu (cecum, appendix, colon, rectum, anus) ndi ziwalo zina. Mwachipatala, gawo lochokera pakamwa mpaka ku duodenum nthawi zambiri limatchedwa kuti m'mimba, ndipo gawo lomwe lili pansi pa jejunum limatchedwa kuti m'mimba. Pali mitundu iwiri yamatenda am'mimba: tiziwalo tating'onoting'ono tating'onoting'ono tambiri tating'onoting'ono. Zilonda zazing'ono zam'mimba zimabalalika m'makoma a gawo lililonse lam'mimba. Zilonda zazikulu zam'mimba zimakhala ndi zotupa zitatu zamatumbo (parotid, submandibular, and sublingual), chiwindi ndi kapamba. Njira yogaya chakudya ndi imodzi mwazinthu zisanu ndi zitatu zazikuluzikulu za thupi la munthu.
