Wake wakwenza lokhu? Uma usukuma ngokuzumayo esihlalweni, embhedeni, noma esihlalweni, uzizwa unesizungu, umbono wakho uba mnyama, futhi uzizwa uphelelwe amandla. Lokhu kuyinto evamile kakhulu kubantu abaningi. Esikhathini esiningi, silinda imizuzwana embalwa bese sibuyela emsebenzini. Kodwa wake wazibuza ukuthi kwenzekani emzimbeni wakho ngaleso sikhathi? Umzimba wakho unesistimu esheshayo, ezenzakalelayo esebenza ukukuvikela. Namuhla, sizoxoxa ngalesi simiso esimangalisayo.
Iyini le Baroreceptor Reflex?
Kalula nje, lesi isilawuli segazi esizenzakalelayo somzimba wakho. Cabanga ukuthi uma ushintsha indawo ngokuzumayo, ikakhulukazi uma usukuma uhleli noma ulele, umfutho wegazi wakho wehla kancane ngokuzumayo. Ngezikhathi ezinjengalezi, uchungechunge olusheshayo lwezenzo zomzimba zokugcina umfutho wegazi wakho usezingeni elijwayelekile lubizwa ngokuthi i-'Baroreceptor Reflex'.
Lokhu kuyashesha kakhulu. Lonke lolu hlelo lwenzeka ngesikhathi inhliziyo yakho ishaya kanye noma kabili. Lena yindlela ebaluleke kakhulu yokulawula umfutho wegazi lethu esikhathini esifushane.
Kusebenza kanjani lokhu? Kuyindlela emangalisayo kakhulu!
Ukuze siqonde lokhu, ake sisebenzise isibonelo esilula. Cabanga ukuthi imithambo yakho yegazi ifana namapayipi enjoloba. Njengoba inani legazi eligeleza kula mapayipi landa, izindonga zamapayipi ziyanwebeka. Njengoba inani legazi lehla, lokhu kwelula kwehla.
Umzimba wakho unezinhlobo ezikhethekile zeziphetho zemizwa ezibizwa ngokuthi ama-baroreceptors . Lezi zifana nezinzwa ezincane. Zitholakala kakhulu emithanjeni yegazi emikhulu entanyeni yakho, umthambo wegazi oyinhloko ophuma enhliziyweni yakho. Lezi zinzwa "zingazwa" ukuthi kungakanani ukucindezela okufakwa kulezo zindonga zemithambo yegazi.
Manje okufanele ukubuke:
1. Uma umfutho wegazi ujwayelekile noma uphezulu: Izindonga zemithambo yegazi zinwebekile kahle. Lawa ma-sensor athumela lowo myalezo ebuchosheni, "Kulungile, umfutho lapha muhle, akukho nkinga." Bese ubuchopho buyajabula ngalokho.
2. Uma umfutho wegazi wakho wehla (kwenzekani uma usukuma ngokuzumayo): Uma usukuma ngokuzumayo, amandla adonsela phansi abangela ukuba igazi elithile lihambe liye emilenzeni yakho. Bese inani legazi eliya ekhanda lakho lehla kancane, kanye nomfutho wegazi lakho. Manje ukucindezeleka ezindongeni zemithambo yegazi kwehla ngokuzumayo. Lapho nje izinzwa zethu zizwa lokhu, ziyesaba futhi zithumele umlayezo ophuthumayo ebuchosheni, zithi, "Ingozi! Ukucindezeleka lapha akwanele! Izindonga azinwebeki!"
3. Impendulo yobuchopho ngokushesha: Ubuchopho busebenza ngokushesha nje lapho buthola lo myalezo. Kufana nokuphendula ucingo oluphuthumayo. Ubuchopho buthumela imiyalo ngokushesha ngohlelo lwakho lwezinzwa:
- Emithanjeni yegazi: "Qinisa ngokushesha!" Lapho imithambo yegazi incipha kancane, ingcindezi engaphakathi kwayo iyanda ngokuzenzakalelayo.
- Enhliziyweni:"Shaya ngokushesha okukhulu!" Lokhu kwandisa ukushaya kwenhliziyo kanye namandla imisipha yenhliziyo efinyela ngawo, kupompa igazi eliningi emzimbeni.
Konke lokhu kwenzeka ngemizuzwana embalwa. Yingakho noma uzizwa unesiyezi kancane, sizophela ngokushesha. Lolu hlelo olumangalisayo lukuvimbela ekulahlekelweni ingqondo.
Kwenzeka nini lokhu ku-reflex?
Le `Baroreceptor Reflex` ingasetshenziswa noma nini lapho kukhona ushintsho emfuthweni wegazi lomzimba wakho. Isibonelo:
- Uma ushintsha izikhundla: Ikakhulukazi uma usukuma ngokuzumayo uhleli.
- Uma usaba ngokuzumayo: Zicabange uhamba emgwaqweni bese inja igxuma phambi kwakho ngokuzumayo. Ngaleso sikhathi, umfutho wegazi lakho nawo uyashintsha, futhi lolu hlelo luyawulawula.
- Uma ushintsha indlela yakho yokuzivivinya: Uma ushintsha indlela ohamba ngayo uye ekugijimeni, umzimba wakho udinga igazi elengeziwe. Lolu hlelo luphinde lungenelele futhi lulungise umfutho wegazi lakho kanye nokushaya kwenhliziyo njengoba kudingeka.
Kalula nje, i-`Baroreceptor Reflex` iyisivikelo esithule esisebenza usuku lonke ukugcina umfutho wegazi lakho uzinzile ngaphandle kokuthi uqaphele.
Yiziphi izingxenye zalolu hlelo? Zikuphi?
Lokhu akuyona into esendaweni eyodwa. Lena inethiwekhi yezingxenye eziningana ezisakazeke emzimbeni wonke. Lawa ma-receptor atholakala kakhulu enhliziyweni yakho, emithanjeni yegazi entanyeni yakho nasemaphashini akho. Ulwazi oluvela lapho luya ebuchosheni, futhi lucutshungulwa kulo lonke uhlelo lwezinzwa.
