Kuqhelekileyo ukwazi ukuba ukutshaya kuyonakalisa impilo. Izinto ezinobuthi ezisuka kwisigaretti etshaya zitshabalalisa iiseli kunye nezicubu zomzimba, bobabini abasetyhini kunye namadoda. Ngomsi wecuba uqulethe malunga nama-4000 amakhemikhali, iimveliso ezinobuthi ezinokubangela indlela yokwenza isisu.
Kubafazi, ingozi yokubhema ixhomekeke ngakumbi. Impilo yabasetyhini ibaluleke kakhulu, kwaye ukutshaya kungabangela umonakalo ongafanelanga. Umzimba wesibhakabhaka unokutshatyalaliswa kakhulu yecuba xa kuthelekiswa nendoda. Umngcipheko wokubakho kwezifo kubasetyhini ababhemayo kuninzi amaxesha angaphezulu. Nangona kunjalo, iqondo lokuphila liphezulu.
Ubunzima bokunyamezela okunjalo bunikezela abafazi, kuba yintlupheko yesini egcina abantu. Ukufumana umntwana, ukuzala, ukondla umntwana. Abafazi abokubhema kufuneka bacinge ukuba ngaba kuyimfuneko ukuchitha amandla omzimba ukulwa neengxube ezenziwe ngumoya wocuba.
Izinto eziphambili ezikhokelela ekungabikho kokusetyenziswa kakubi kotywala nokutshaya. Ucwaningo olukhulu lwabafundi beNgesi, apho abafazi abangaphezu kwe-17 000 bathatha inxaxheba, babonisa ukuba inani leekheyidi ezibhemayo ngosuku lihluke ngokulinganayo kwikhono lomfazi lokukhulelwa, ukuthwala nokuzala umntwana. Oko kukuthi, ukubhema utshayi kunempembelelo embi kumfazi ukuba akwazi ukukhulelwa aze abelethe umntwana.
Ngokweenkcukacha zenzululwazi, iigarethi zineemveliso ezizenzayo kwiiseli zokuzala zesisu - amaqanda. Iqanda elonakalisiweyo alinakuqhelisa isidoda esivamile, ngoko umzuzwana we-fusion yamaseli wesini kunye namabhinqa ayinakwenzeka. Yaye nangona ukukhulelwa kwenzeke, iqanda lomntwana liza kuhlakulela ngokungalunganga kwaye umntwana lowo uza kufa kwizigaba zokuqala zophuhliso.
Ulungelelaniso olucacileyo lufunyenwe: ixesha elide lobomi bowesifazane otshaya, ngakumbi inani leeqanda liyonakaliswa. Ixesha elide lokubhema umfazi linokuthelekiswa nokususwa ngokupheleleyo kwee-ovari, kuba ukutshaya akuchaphazeli nje amaqanda kuphela, kodwa nakwiibhulo ezinqabileyo, okwenza ukuba kungabikho.
Iimbumba ezinamaqabunga zihlanganiswe ne-epithelium eciliated. Le nto yincinci kwaye iyicala. Olunye ugwayi lwanele ukuba lubangele umonakalo omkhulu: iibhoksi zitshabalalisa i-cilia. Ngaloo ndlela, oku kubangela ukuba iqanda elixutywe ngamanzi lingenakunqumla kwisigxina se-uterine, unamathele eludongeni lwayo kwaye uqale ukuphuhlisa. Endaweni yoko, iqala ukwahlula kwiibhulo ezikhohlakeleyo, ezikhokelela ekukhulelweni kwe-ectopic, kwaye emva kokusweleka.
Inqaku elithakazelisayo kukuba abazali ababhema abazali banamathuba angama-2 ukuba banamantombazana kunamakhwenkwe. Oku kungenxa yokuba umntwana obengenayo i-Y-chromosome, efunyenwe kwipapa, angafa kwizigaba zokuqala zokukhulelwa ngenxa yeziphumo ezinobungozi be-cigarettes. Kwaye kunye nokukhulelwa okuphumelelayo, ababhemayo banamathuba ambalwa okuzala izithelo baze babele umntwana oqhelekileyo.
Kwaye kwavezwa ukuba ukungahambi kakuhle kwamanye abantu phakathi kwabokutshaya kubangamaxesha aphindwe kabini. Oku kubangelwa ukuba i-nicotine inciphisa i-lumen yemithana yegazi, ekhusela iiseli zegazi ukwenza imisebenzi yazo-ukuhambisa i-oksijeni kwi-placenta nokususa i-carbon dioxide. Kwiimeko ezinzima, umntwana usenokufa ngenxa ye-oksijini yindlala.
Ngethuba lokunikezelwa, ukutshaya abafazi nabo bavelele engozini enkulu: ukulahlekelwa igazi okukhulu ngenxa ye-placenta engavumelekanga, leyo eyenzekayo, ingakhokelela ekufeni komntwana wengane.
Abafazi ababhemayo bavame ukuzala abantwana ababuhlungu, ababuthathaka okanye abalahlwayo. Ngoko ke, ukucwangcisa ukukhulelwa, kucetyiswa ukuba uyeke ukutshaya 1.5 iminyaka ngaphambi kokuba ukhulelwe. Kukholelwa ukuba eli xesha liwanele ukwenzela ukuba umzimba wesetyhi uhlambuluke kwiibhoksi ze-cigarettes.
Ukutshaya okanye ukungafuni - kufike kuwe. Kodwa khumbula ukuba ukutshaya kakubi nje kuphela, kodwa nabo bantu bakujikelezile. Wonke umfazi oqhelekileyo amaphupha omntwana omhle, onempilo, onobuqili, kwaye oku kunokwenzeka ukuba ukhusela umzimba wakho kwimiphumo emibi yezinto ezinobuthi, ngakumbi ucuba. Cinga malunga nokuba kunzima kangakanani kumzimba omncinci ngaphakathi kwakho ukuphefumula umsi wecuba, ngelixa ukhula kwaye ukhula.
