Izinto zokwakha zeBhunga loLuntu
Amanqaku enyango kunye neyokuqala ngoncedo asebenzisa rhoqo amagama angenangqiqo kumxholo okanye ukuba awuqhelanga nabo. Ukuba ngaba bengenangqiqo kwisiqwenga, kunokutshintsha ngokupheleleyo indlela oyiqonda ngayo.
Nanku kukukunceda ngezona zinto ezisisiseko kuzo zonke izixhobo zokwakha ezisisiseko zomzimba: iiseli , izicubu kunye namalungu .
Ezi zezizathu zomzimba wonke. Emva kokuba unalo, siyakwazi ukuqhubela kwiinkqubo zesebe okanye ufumane ngakumbi, njengenkqubo ye- nervous .
Iiseli
Iiseli ziyunithi encinci yobomi. Ukuqonda ukuba iseli libukeka njani, yifaka iqanda le inkukhu. Inomlenze wangaphandle (kwimeko yeqanda, igobolondo nzima, kodwa iiseli ezininzi azifani noko); Izaliswe ngumthamo ocebileyo wezondlo (abamhlophe beqanda ngokumelene ne-cytoplasm kwiseli) kunye ne-nucleus (iqanda leqanda).
Azikho zonke iiseli ezibukeka ngokufanayo. Amaseli emisipha ahlala ende, anqabile kwaye agutyungelwe kwi-myelin, ukukhutshwa kwemvelo. Amaseli omzimba aqhuba iimpembelelo, ezisetyenziselwa ukuthetha. Ziyizona zixhobo zomnxeba zomzimba, kwaye ziyinxalenye. Amaseli omzimba ayanqamle kwaye anxiliswe, njengamaqela e-raber ephilayo. Iiseli zegazi ezibomvu zithe cwaka kwaye zenziwe nge-oval. Imilo yeseli ibancedise ngemisebenzi yabo.
Isitye ngasinye senza injongo enye emzimbeni.
Inkontileka yeeseli zesisipha kunye neeseli zesisindo zihambisa iimpembelelo. Iiseli zegazi ezibomvu zibophelela kwi-oksijini, ngelixa iiseli zegazi ezimhlophe zilwa nesifo.
Tissues
Xa iiseli zodidi oluthile ziqokelelene ndawonye, isakhiwo esiphumela sibizwa ngokuba sisiqununu. Kukho izicubu ze-muscle, ezenziwa ngamacandelo eesistim. I-Adipose tissue yinye isalathisi yesikhumba esenziwe ngamaseli atyebileyo.
Iisisombululo ezinxibelelwano ligama elisetyenziselwa iintlobo ezahlukahlukeneyo ezinobunzima, into enobumba njengamathambo okanye iigaments.
Uninzi lwexesha ekuncedeni kuqala, sibhekisela kwizicubu ezingaphezulu kweeseli. Amaseli aqhelekileyo amancinci, ngelixa izicubu zingabonwa kwaye zilawulwa. Xa ukhangela i- laceration ukuqinisekisa ukuba ngaba ufuna iimpawu , u khangela izicubu ze-adipose kwilonda. Eneneni, izibonda zibamba ndawonye izicubu, kungekhona iiseli.
Amalungu
Xa iintlobo ezahlukeneyo zezicubu zihlelwe ndawonye ukuze zenze umsebenzi oyingxubevange, ubizwa ngokuba ngumzimba. Inhliziyo iyilungu. Inesisundu sezihlunu, izicubu ezixhumeneyo, kunye nezicubu zesiswini zonke zisebenza kunye ukupompa igazi.
Amalungu angenza imisebenzi engaphezu kweyodwa kunye nomsebenzi ngamnye unokuba nzima kakhulu. Amehlo enombala umbala, ukunyakaza kunye nokukhanya. Zihamba kwaye zijolise. Ilungu elikhulu kunalo (okanye okanye) nomzimba womntu lukhupha. Umzekelo omhle weetekisi zeethambo ezisebenzisana ukwenza imisebenzi emininzi:
- ephethe amanzi
- lawula ubushushu
- uvakalelo lokushisa kunye noxinzelelo
Umbutho we-anatomy uqala ngezi zakhiwo ezintathu. Ingaba uthetha malunga nezicubu ezincinci zengqondo okanye ubunzima besithambo, kusenziwa ngamaseli abanjwe ndawonye kunye nezicubu kunye neziqu.
