Khungu lanu ndilo chiwalo chachikulu kwambiri cha thupi lanu, chopangidwa ndi zigawo zingapo zosiyanasiyana, kuphatikizapo madzi, mapuloteni, lipids, ndi mchere ndi mankhwala osiyanasiyana. Ntchito yake ndi yofunika kwambiri: kukutetezani ku matenda ndi kuwonongeka kwina kwa chilengedwe. Pakhungu palinso minyewa yomwe imamva kuzizira, kutentha, kupweteka, kupanikizika, ndi kukhudza.
Pa moyo wanu wonse, khungu lanu lidzasintha nthawi zonse, labwino kapena loipa. M'malo mwake, khungu lanu limadzikonzanso lokha kamodzi pamwezi. Kusamalira khungu koyenera ndikofunikira kuti mukhale ndi thanzi komanso nyonga za chiwalo chotetezachi.
Khungu limapangidwa ndi zigawo.Zimapangidwa ndi nsalu yopyapyala yakunja (epidermis), yowonjezereka yapakati (dermis), ndi yamkati (minofu ya subcutaneous kapena hypodermis).
TKhungu lakunja la khungu, epidermis, ndi gawo lowoneka bwino lopangidwa ndi maselo omwe amagwira ntchito kutiteteza ku chilengedwe.
Dermis (wosanjikiza wapakati) ili ndi mitundu iwiri ya ulusi umene umachepetsa chifukwa cha msinkhu: elastin, yomwe imapangitsa khungu kukhala lolimba, ndi collagen., zomwe zimapereka mphamvu. Dermis ilinso ndi zotengera zamagazi ndi zamitsempha, zitsitsi zatsitsi, zotupa za thukuta, ndi zotupa za sebaceous, zomwe zimatulutsa mafuta. Mitsempha mu dermis imamva kukhudza ndi kupweteka.
Hypodermisndi mafuta layer.Minofu ya subcutaneous, kapena hypodermis, nthawi zambiri imakhala ndi mafuta. Ili pakati pa dermis ndi minofu kapena mafupa ndipo imakhala ndi mitsempha ya magazi yomwe imakula ndikugwirizanitsa kuti thupi lanu likhale lotentha nthawi zonse. Hypodermis imatetezanso ziwalo zanu zofunika zamkati. Kuchepa kwa minofu mumsewuwu kumapangitsa khungu lanu kukhala losalalag.
Khungu ndi lofunika pa thanzi lathu, ndipo chisamaliro choyenera ndi chofunika. A wokongolandi wathanzimaonekedwe ndi otchukam'moyo watsiku ndi tsiku komanso moyo wantchito.
