Umsebenzi kwesikhumba kwabantu

Imisebenzi esikhumba ezahlukahlukeneyo yaye zonke badlala indima ebalulekileyo umzimba womntu. Okokuqala, inshorensi zethu zendalo ikhusela umzimba. Isikhumba - uhlobo ngumqobo phakathi kweenkqubo zangaphakathi kunye nehlabathi ngaphandle. Ukuba uvumela ukukhusela umzimba emanxebani, ukugruzuka kunye nengcinezelo, okt ukususela kwiimpembelelo mechanical. Gcina i data kuthi ngemvelo kwaye ibandakanya kwimiphumo zemichiza - asidi kunye alkalis, kuba ngaphandle kobunyulu akukho kweendleko, indlela yethu yobomi. Isikhumba uyasikhusela kwimpembelelo engentle yokusingqongileyo (ilanga, umoya, ubushushu nengqele) kwakunye kwii emzimbeni iintsholongwane kunye nosulelo ezahlukeneyo zale kunye imitha infrared.

Mechanical zikhusela ulusu zenziwa Bulelani nokukwazi sangaphandle ukuze abuyisele, kwakunye ngenxa kubume kwilastiki le dermis, kunye neempawu ezithile ze ifayibha yayo. indima enkulu ekuphumezeni intshukumo umenzi ukukhusela umaleko phezulu inshorensi zethu zendalo. Amandla okubuyela kwimo yazo sangaphandle kuqinisekiswa yi phambi kumafa kwalo iiprothini kunye lipids. Dermis isetyenziselwa ukuhlawula luvukelo zendalo komsipha ngezenzo ngoomatshini.

An zikhusela ebalulekileyo ulusu kukukhusela umzimba kwimiphumo radiation. Ukongezelela kwelanga, iphembelela yabantu iye kunye yelanga. Le ezinawo corneum ulusu ukukhusela lunyuka yokuqala kwimiphumo emibi radiation. yelanga eyingozi, bakwimeko kuluhlu ethile, ukuba impendulo elibi kumgangatho we sangaphandle. Oku kunokubangela tikaka, yaye kamva, kunye nomhlaza. yelanga eyingozi, nto leyo kusichukumisa kungena ungqameko ezinzulu dermis, ukuphucula uvakalelo elangeni kwaye kungakhokelela ekubeni kwesikhumba cover bendalo umzimba. Impendulo Ukwakheka yesikhumba tikaka. Ngenxa yoko isixa esikhulu sombala elenza ray kwindawo ezininzi ezahlukeneyo. umbala esikhumba ngexesha elifanayo etshintsha ukuba mnyama. Ngoko ke, izihlunu zomzimba zikhuselekile ukusuka elihlala livelile phezulu.

Umsebenzi nesikhumba singena kwinxalenye yomzimba exchange igesi. Kwiiseli inshorensi yendalo kusichukumisa ioksijini, ammonia, icarbon dioxide kunye emanzini. Kulo mba, umsebenzi sokuphefumla ulusu kuthathelwa ingqalelo ngexesha iinkqubo izithambiso. Mayisoloko ikhunjulwa into xa uthatha leebhate zeoli, sebenzisa ukuba unyango yodaka kuliyeza.

Isikhumba likwanoxanduva nokulondolozwa thermoregulation lomzimba. Zombini ebusika yaye ehlotyeni ngenxa level lobushushu ayitshintshi kwaye kwi 36.6 degrees.

Ukungena ngenxa amanqatha imijelo iinwele kunye ezahlukeneyo imichiza zibandakanywa umsebenzi ngezondlo ulusu. Olu phawu iqukiwe kuphuhliso izithambiso izithambiso kunye nezisombululo. oyile Yemifuno kunye amafutha ezilwanyana, izongezo zokutya kunye neevithamini ifakiwe amachiza bafakwe sangaphandle kwaye kuyo nefuthe layo nezinyangayo.

Kwimisebenzi nesikhumba somntu ziquka ukukwazi ukuba alihlambulule ngokwayo. Indima ephambili kule nkqubo bobabo ngokubila kunye namadlala sebaceous, apho umzimba ukhupha ezinye iimveliso eziyingozi emzimbeni (urea, ammonia, njalo njalo).
