Ummiselo Humoral kunye neenkqubo zobomi

Evolution kukhokelela ngokubonakala iindidi utshintsho umzimba eziphilileyo, nto leyo yanceda ukuba aqhelane iimeko yokusingqongileyo ukuze sisinde kweli hlabathi. Xa sithethe utshintsho esinayo engqondweni kungekuphela nje iimpawu zangaphandle, utshintsho yangaphakathi emzimbeni zibalulekile kude kangangoko enkulu. Okokuqala, elidityaniswe neenkqubo yobomi nayiphi ephilayo. Kumanqanaba okuqala izinto zazivelela waqala ukubonakala ummiselo humoral, njengoko enye yezi ndlela zeenkqubo.

ixabiso layo inkulu ngokwaneleyo kuba zonke izinto eziphilileyo, kuba ivumela ukuba nokulungelelanisa ezahlukeneyo iinkqubo yebhayoloji kunye imichiza yi ulwelo. Oku lo msebenzi wenziwa ummiselo humoral. Njengoko medium ulwelo izenzo igazi, nkovu, kunye ulwelo ezahlukeneyo zomzimba, njengoko zibalulekile ukuba umzimba bona ubukhulu becala zenza inxalenye ebalulekileyo yalo. ummiselo Humoral Kungumbulelo ukuba into yokuba iiseli, ancedisana amalungu ebomini babo cell ezahlukeneyo izinto eziphilayo esebenzayo. Ezi ziquka, kuqala, iihomoni kunye metabolites, kodwa zikho ezinye iintlobo.

ummiselo Humoral abantu

Inkqubo yaqala ukuba ziyaphuma eziphilayo ixesha elide, nto ifumaneka ezininzi, kodwa umahluko ezithile ngokuxhomekeke kwifom ethile. Ingakumbi abantu, ngokunjalo ezinye iintlobo zezilwanyana ezinzima kakhulu: ezi nkqubo zixhomekeke kumgaqo luvo. ummiselo Wayesoyika humoral kunye zenza inkqubo esebenza enye. igama layo zesayensi ummiselo neurohumoral, kwaye efundwayo njenge umthetho, kuphela kule fomu.

Ngexesha nethe cell ukuba imveliso ethile echaphazela amalungu effector kunye luvo, amaziko luvo. Ngaloo humoral okanye reflex okubangelwa reactions ezithile eziyimfuneko kwimisebenzi yomzimba eqhelekileyo.

Xa siqwalasela umzekelo indlela enjalo lomzimba womntu, abanye babo uqala ukusebenza xa ufuna ukubuyisela imisebenzi ebalulekileyo. Ngexesha umzimba ibalekisa ukutya, odlisa ubomi nokubetha kwentliziyo nokuphefumla. Umthwalo izihlunu ivuselela imfuneko akhawulezise nokubetha kwentliziyo, ukuba ubanike mpilo. Oku kukhokelela ekubeni igazi libe kakhulu CO2, kodwa ukuze ayibulale kufuneka ube ukuphefumla lwaqho - kuba umzimba ulibuyele yokunqongophala kwe-oksijini aze balahle carbon dioxide. Lo ngumzekelo womthetho humoral.

ukulawula uvalo

Ukusuka zingasentla, kucacile ukuba ezi nkqubo zihlala zibalulekile ukuze omzimba aphuhlileyo kakhulu yaye zifumaneka kuyo yonke. Abantu, bonke eqhagamshelwe kwisixokelelwano enye neurohumoral, ngenxa yokuba nayiphi na impendulo okubangelwa inkqubela luvo ezosulela ngqo iikhemikhali - neurotransmitters. Ngelo efanayo ixesha inxaxheba kwiinkqubo ezinjalo kunye nezinye izinto, kuquka iihomoni. Khawuthelekelele ukusebenza kwenkqubo ngaphandle ikhonkco eyodwa akunakwenzeka. Kwakhona kuyimfuneko ukuze bakuthathele ingqalelo into yokuba lo ummiselo humoral kwemisebenzi umzimba lwenziwa rhoqo, kodwa ayikwazi kuqhubeka emhlabeni wonke.

Ukwenza iinkqubo ezinjalo kufuneka ithathele ingqalelo zonke iimpawu kwiincindi zomzimba. Ngokukodwa, umsebenzi wabo lomzimba kuxhomekeke kwisiqulatho ezithile izinto ezahlukeneyo kuzo - iadrenaline, catecholamines, histamine, acetylcholine, serotonin, enzayim ezahlukeneyo kunye inhibitors, kunye nabanye abaninzi. Ngako oko, ibhekisela iinkqubo zolawulo ukuba zenzeke ngoncedo ezi ncindi, kuyimfuneko ukuba ukuthatha ingqalelo ukwakhiwa kwawo.
