Sonke sikubonile: sitshatile okanye ibhavu elide, okanye uhambe ukubhukuda, kwaye uqaphela iingcebiso zeminwe yakho. Siyasetyenziswa kuyo, kodwa ngaba siyazi ukuba kutheni le nto yenzeka? Impendulo emfutshane "ayikho." Akukho mntu uyayiqonda ngokwenene isizathu sokuba iminwe yethu idubane, nangona kukho iingcamango ezithile. Okwangoku, nangona kunjalo, kusekho impikiswano malunga nokuba kutheni iminwe yethu ibomile.
Kukho ezinye izinto esiziyo. Okokuqala kukuba, ngokuchasene noko abantu abaninzi bacinga, inkqubo yokunxiba ngomunwe ayikwazi ukuchazwa nje nge-osmosis. Uninzi lwabantu bacinga ukuba ngokufaka izandla zakho emanzini, izandla zifaka amanzi esikhumbeni kwinkqubo ebizwa ngokuba yi-osmosis, ebangela ukuba isikhumba siphazamise. Iinyaniso kukuba, ngelixa amanzi enokubangela ezinye iindawo eziphezulu zesikhumba ukuba zihlume, kukho nendima ebalulekileyo yemithwalo yegazi kunye nokuphela kwezibilini ezinokubangela ukunqanda isikhumba.
Siyazi ukuba i-osmosis ayibhali ngokunyanyiswa komunwe ngezizathu ezimbalwa:
- Okokuqala, kuphela isikhumba seminwe kunye neenzwane ezinobunzima - i-osmosis yayiza kubangela ukuba zonke izikhumba ziphazamise ukuba oko kwakuyiyo nkcazelo.
- Okwesibini, ukuba unqumle umvuthwa onovelwano kwiminwe, ayisekho nkinga!
I-System yeNervous
Icandelo elinye lomnxeba womnxeba ukubandakanyeka kwenkqubo yokukhathazeka, okubalulekileyo ekulawuleni imisebenzi emzimbeni, kuquka intlawulo yenhliziyo kunye negazi.
Inkqubo yentswela-mva iyinxalenye yesimiso se-nervous eyaziwa ngokuba yimpendulo "yokulwa okanye yendiza". Imithambo yegazi yomda wexesha elimandla xa umonakalo we-nervous sympathetic is activated, ukuguqula igazi ukuya kwiziko lomzimba kunye nezisundu ezinkulu kunye namalungu. Usebenziso olusondeleyo lweentsholongwane kucatshangelwa ukuba lukhutshulwa olukhokelela ekumanyeni komunwe.
Ivazi yegazi
Xa inkqubo ye-nervous sympathetic is activated, kwaye imithwalo yegazi yeminwe inomda, umthamo owehlayo kwiindawo ezincinci zezicubu ezithambileyo zisusa isikhumba, ekudaleni amahlumela esiwaziyo njengamabhanki.
Kuyathakazelisa ukuba ukufaka isandla sakho emanzini afudumele kubangela ukuba imilambo yegazi ithinte. Kwakhona, abaninzi abantu banokulindela ukuba imivenge yegazi iyancipha - impendulo yomzimba yethu ngokuqhelekileyo kwimfudumalo.
Kutheni Iminwe idibanisa?
Kwakhona, kukho impikiswano eqhubekayo malunga nokuba kutheni imizimba yethu ikhulise le khono lokukhazamisa isikhumba.
I-theory esandul 'ingcatshangelwa kakhulu kukuba ukukhwabanisa kwesikhumba kuvumela amandla angcono okubamba izinto ngeminwe eminwe. Ngokudala "ukunyathela" kufana neendwangu zokutya, iminwe iboniswe ukuba iqonde izinto ezimanzi kangcono xa kwenzeka impendulo.
Kuye kwafundiswa imodeli ebomvu yeminwe, kunye nabaphandi bafumanisa ukuba kusebenza emanzini okujikizela ngaphandle kwesikhumba, okuvumela ukulungiswa kakuhle kwizinto ezimanzi. Abaphandi baye bafumanisa ukuba abo bantu abanesikhumba esinexesha lokubwinya babenokukwazi ukuphatha izinto ezimanzi. Aba baphandi bacinga ukuba isizathu sokuphikisana kubonakala kuphela kwizandla kunye neenyawo kukubaluleka kokubamba, kwaye ngoko kutheni umzimba wonke ungaphazamisi xa ugxila emanzini.
Le yinto enye yamuva, kwaye ngokuqinisekileyo inabantu abaninzi becinga ukuba basombulule ingxaki. Kodwa oku akusiyo inkolelo yokuqala ecetywayo ukucacisa umlenze womnxeba, kwaye akunokuba ngowokugqibela. Enye yezinto ezinomdla ekufunyanweni kwenzululwazi kukuba njengoko iicatshulwa zicetywayo, zivame ukwenza ingqiqo. Nangona kunjalo, loo nto ayibenze ibe yinyani, kwaye abanye baye bathetha iingcamango zokuba kutheni iminwe ingabonakali nantoni kunye noxinzelelo. Ngethamsanqa, ukuxazulula le ngxaki kunokwanelisa umnqweno ngaphezu kweminye imibuzo yesayensi!
