Ngaba singayifunda ibhalansi emangalisayo (iHomeostasis) emizimbeni yethu?

Khawuthelekelele ufika ekhaya uvela ekubalekeni ixesha elide uze udlale. Umzimba wakho udiniwe kakhulu, ubila kakhulu, kwaye uphefumla kakhulu. Kodwa emva kwexesha elithile, konke oku kubuyela esiqhelweni, akunjalo? Okanye, ngemini ebanda kakhulu, umzimba wakho uyangcangcazela. Kutheni oku kusenzeka? Emva kwako konke oku kukho 'inkqubo ezenzekelayo' emangalisayo emzimbeni wethu. Ngaphandle kokuba siqaphele, le nkqubo isebenza ukugcina yonke into engaphakathi emzimbeni wethu ikwinqanaba elifanelekileyo. Namhlanje sithetha ngale nkqubo imangalisayo, eyi-homeostasis.

Ngamafutshane, yintoni i-homeostasis?

I-Homeostasis yinto elula kakhulu. Yinkqubo apho umzimba ugcina khona imeko-bume yangaphakathi (ubushushu, amanqanaba eoksijini, amanqanaba eswekile, njl.njl.) izinzile kwaye ilungelelene ngamaxesha onke. Kanye njengokuba i-radiator yenjini yemoto isebenza ukugcina ubushushu benjini bukwinqanaba elifanayo.

Eli gama lenziwe ngamagama amabini esiGrike. Elithetha "ukulingana" kunye "nokuzola." Oko kukuthi, ukugcina yonke into ikwinqanaba elifanelekileyo, kwinqanaba elifanelekileyo. Olu lungelelwaniso aluthethi ukungawi xa sihamba, kodwa luthetha ukugcina yonke into engaphakathi emzimbeni "ikwinqanaba elilinganayo."

Kubaluleke kakhulu ukugcina le 'venkile'. Kuba, nokuba zezona zinto zibalulekileyo kuthi, ukuba ziba zininzi kakhulu, zinokuba yingozi. Cinga ngamanzi. Asinakuphila ngaphandle kwamanzi. Kodwa ukuba usela amanzi amaninzi ngaxeshanye, kunokubangela imeko eyingozi ebizwa ngokuba yi -hyponatremia (amanqanaba aphantsi esodium egazini) . Kunjalo nangeoksijini. Asinakuphila ngaphandle kweoksijini. Nangona kunjalo, ukuba uphefumla ioksijini ecocekileyo ixesha elide kakhulu, unokufumana ubuthi beoksijini . Zombini ezi zinto zinokubulala. Ngoko ke, ngoku uyaqonda ukuba kubaluleke kangakanani ukugcina yonke into ilungelelene, akunjalo?

Ngoko ke, le nkqubo yenzeka njani emzimbeni?

Le nkqubo ye-homeostasis yenzeka ngokuzenzekelayo ngokupheleleyo, oko kukuthi, ngokuzenzekelayo. Asinyanzelekanga nokuba sicinge ngayo. Inxalenye encinci yobuchopho bethu ebizwa ngokuba yi-hypothalamus yindawo ephambili elawula konke oku. Njenge-CEO yenkampani enkulu.

Kukho iindlela ezimbini eyenzeka ngazo le nkqubo.

1. Ingxelo Engalunganga

2. Impendulo Entle

Masithethe ngokucacileyo ngezi zimbini ngoku. Ukuze uqonde umahluko phakathi kwezi zimbini ngokulula, jonga itheyibhile engezantsi.

1. Inkqubo yeNgxelo engalunganga

"Into embi" apha ayithethi "imbi." Kuthetha ukuba xa umzimba ubona utshintsho, uzama ukulubuyisela okanye ukuluchasa olo tshintsho lungafunekiyo. Le yindlela esebenza ngayo uninzi lweenkqubo ze-homeostasis emizimbeni yethu.

• Ubushushu bomzimba: Khawuthelekelele ukuba ushushu kakhulu. Xa ingqondo yakho ikubona oku, ikuxelela ukuba ubile. Njengoko umbilo uphuma, umzimba wakho uyaphola. Kwakhona, ukuba ubanda, izihlunu zakho ziqala ukungcangcazela. Oku kungcangcazela kuvelisa ubushushu kwaye kufudumeze umzimba wakho. Le 'yi-heater' yendalo yomzimba wethu kunye 'ne-AC'.
• Uxinzelelo Lwegazi: Xa usuka ngequbuliso esihlalweni, inxalenye yegazi eya entlokweni yakho itsalwa phantsi ngumxhuzulane. Kwangaxeshanye, inkqubo yethu iyangena, inciphise imithambo yegazi, ikhawulezise isantya sentliziyo kancinci, kwaye igcine ukuhamba kwegazi okuqhelekileyo ukuya ebuchotsheni. Yiyo loo nto singasoloko siziva sinesizungu.
• Ukulinganisela ulwelo emzimbeni: Ukuba usela amanzi amaninzi, kuya kufuneka uchame emva kwexesha elithile. Oku kukususa ulwelo olongezelelweyo emzimbeni nokugcina yonke into 'icocekile'.
• Amanqanaba eoksijini: Xa uzilolonga, izihlunu zakho zifuna ioksijini engaphezulu. Ngelo xesha, izinga lokuphefumla kwakho kunye nesantya sentliziyo ziyanda ngokuzenzekelayo. Le oksijini eyongezelelweyo ithunyelwa emzimbeni wakho wonke ngokukhawuleza. Xa ugqibile ukuzilolonga, zombini ezi zinto zibuyela kwisiqhelo.

2. Inkqubo yeNgxelo Elungileyo

Impendulo eyakhayo yinkqubo yokuqinisa nokukhawulezisa inkqubo esele iqalile. Oku kuyaqhubeka de kususwe unobangela obangele le nkqubo.

• Ukuzala Nokuzala: Xa ukuzala kuqala, umlomo wesibeleko uqala ukwanda. Oku kukhula kuthumela umyalezo engqondweni. Ukuphendula, ingqondo ikhupha ihomoni ebizwa ngokuba yi-oxytocin . Le homoni ibangela ukuba isibeleko siqine ngakumbi. Njengoko isibeleko siqina ngakumbi, umlomo wesibeleko uyakhula ngakumbi, nto leyo ebangela ukuba kuveliswe i-oxytocin engaphezulu. Lo mjikelo uyaqhubeka de umntwana azalwe kwaye umlomo wesibeleko ubuyele kwindawo yawo eqhelekileyo.
• I-Hemostasis: Xa unesilonda engalweni okanye emlenzeni kwaye wopha, izinto ezibangela ukujiya kwegazi ziyadibana ukuze zincede ukuvala inxeba. Ayipheleli apho, kodwa zikwaqokelela izinto ezibangela ukujiya kwegazi kwindawo leyo, ngokungathi zicela uncedo olungakumbi. Olu "bizo loncedo" luyaqhubeka de ukopha kuphele ngokupheleleyo.
• Impendulo yomzimba kunye nokudumba: Xa umzimba wethu uchaphazeleka kusulelo okanye ukwenzakala, inkqubo yethu yomzimba yokuzikhusela ibangela ukudumba. Oku kudumba kufana nokukhanyisa indawo yokwenzakala. Kuxelela iiseli zomzimba ngqo apho kufuneka ziye khona. Iiseli zigcina ukudumba kuqhubeka de zifune uncedo olungakumbi.

Kutheni le nto olu lungelelwano lubaluleke kangaka kuthi?

Ngamafutshane, asinakuphila ngaphandle kwe-homeostasis. Zonke izifo, zonke iimeko zempilo esizaziyo, ziphazamisa le nkqubo ye-homeostasis ndaweni ithile.

Xa ugula okanye wenzakele, umzimba wakho utshintsha ezi nkqubo ze-homeostatic ukuze zikuncede uphile. Umzekelo, umkhuhlane uyenzeka xa unentsholongwane, igazi liyajiya xa wenzakele, kwaye umzimba uzama ukubuyisela olu lungelelwaniso.

Nangona kunjalo, ngamanye amaxesha le nkqubo ayikwazi ukuyisombulula ingxaki. Kulapho kuvela khona iimeko ezingapheliyo.

• Uxinzelelo lwegazi oluphezulu (iHypertension): Le meko yenzeka xa umzimba ungakwazi ukugcina uxinzelelo lwegazi lukwinqanaba elifanelekileyo.
• I-Osteoporosis: Esi sifo senzeka xa umzimba ungakwazi ukwakha izicubu ezintsha zamathambo ngesantya esifanayo nesokususwa kwe-calcium emzimbeni.

Ezinye izifo zivela kuba le nkqubo ye-homeostasis ngokwayo ayisebenzi kakuhle, nto leyo eyenza imeko ibe mandundu.

Iinkqubo ezahlukeneyo emizimbeni yethu zinegalelo njani koku?

I-Homeostasis ayipheleli kwinkqubo enye kuphela. Yimizamo yeqela lomzimba wonke.

Inkqubo yeNervous

Inkqubo yethu yemithambo-luvo ifana ne-accelerator kunye neebhuleki zemoto. Ezi nkqubo zimbini zisebenza ngokuchaseneyo, zigcina yonke into ilungelelene.

• Inkqubo yemithambo-luvo enovelwano: Le 'yi-accelerator' yethu. Ngamaxesha engozi, le nkqubo ivuselela impendulo "yokulwa okanye ukubaleka".
• Inkqubo yemithambo-luvo ye-Parasympathetic: Eli 'likhefu' lethu. Le nkqubo iyaphumza kwaye izolise umzimba xa sikhuselekile kwaye sikhululekile.

Inkqubo Yamathambo

Amathambo ethu ahlala etshintshwa. Izicubu ezindala zamathambo ziyaqhekeka kwaye kwenziwa ezintsha. I-calcium kunye ne-vitamin D zibalulekile ukuze le nkqubo yenzeke ngokufanelekileyo. Le nkqubo iyancipha njengoko sikhula. Ukuba ithambo elitsha alidalwanga ngesantya esifanayo nethambo eliqhekekayo, iimeko ezifana ne -osteopenia okanye i-osteoporosis zinokwenzeka.

Inkqubo yokuphefumla

Ukuphefumla kwethu kulawula neenkqubo ezininzi ze-homeostasis.

• Amanqanaba eoksijini: Xa sibaleka, siphefumla nzima ukuze umzimba ufumane oksijini engaphezulu.
• I-pH yegazi: Inkqubo yokuphefumla isebenzisa i-carbon dioxide ukulawula ibhalansi ye-asidi-base yegazi lethu. Ukuba le bhalansi iyaphazamiseka, iimeko ezifana ne -respiratory acidosis okanye i-respiratory alkalosis zinokwenzeka.

Inkqubo ye-Endocrine

Le nkqubo kulapho umzimba wethu uvelisa khona iihomoni. Iihomoni zifana neekhemikhali ezithumelayo. Ezi homoni zinceda ekulawuleni izinto ezininzi, kubandakanya ukugaya ukutya, imetabolism, kunye nokusebenza kwenkqubo yokuzala.

Njengakwibali, imizimba yethu isebenza kakuhle xa yonke into "ilungile." Ngokuqonda indlela esebenza ngayo le nkqubo ye-homeostasis, singanceda imizimba yethu igcine olo lungelelwano. Mhlawumbi kukusela amanzi amaninzi, okanye ukuhambahamba, okanye ukuthatha amayeza afanelekileyo kwimeko ethile. Ukugcina olu lungelelwano kunokwenza umahluko omkhulu kumgangatho wobomi bethu.
