Ingabe uzizwa unesizungu uma usukuma ngokuzumayo? Kungenzeka yini ukuthi kungenxa ye-Baroreceptor Reflex?

Wake wazizwa unesiyezi noma uzizwa unekhanda elibuhlungu lapho usukuma ngokuzumayo uhleli, noma lapho uvuka ngokuzumayo ulele? Ngezinye izikhathi kungaze kuzwakale kunesiyezi. Abantu abaningi banalokhu okuhlangenwe nakho. Pho kungani lokhu kwenzeka? Umzimba wethu uyisimiso esimangalisayo kakhulu. Unezindlela ezahlukene zokusigcina siphilile futhi silinganisela. Namuhla sizokhuluma ngenye indlela ekhethekile. Ibizwa ngokuthi i-Baroreceptor Reflex .

Iyini i-Baroreceptor Reflex? Kalula nje...

Kalula nje, i-baroreceptor reflex uchungechunge lwezenzo umzimba wakho ozithathayo ngokushesha kakhulu ukugcina umfutho wegazi lakho usezingeni elijwayelekile lapho umfutho wegazi wakho ushintsha ngokuzumayo. Lokhu kubaluleke kakhulu uma ushintsha indawo yakho, isibonelo uma usukuma usuka endaweni yokuhlala. Kuyindlela esheshayo kakhulu, eyenzeka ngaphakathi kokushaya kwenhliziyo yakho, uma kuqondile. Kuyindlela eyinhloko umzimba wethu olawula ngayo umfutho wegazi wethu ezimweni zesikhashana.

Lokhu (i-Baroreceptor Reflex) kusebenza kanjani? Kuyamangalisa ngempela!

Cabanga ngalokhu ngale ndlela: Uma umfutho wegazi lakho ushintsha, izindonga zemithambo yakho ziyasabela ngokufanele. Isibonelo, uma umthamo wegazi lakho ukhuphuka, izindonga zemithambo yakho ziyanwebeka. Kwezinye izingxenye zomzimba wakho, kuneziphetho zemizwa ezikhethekile ezibizwa ngokuthi ama-baroreceptors . Lezi zifana nezinzwa ezincane. Lezi zinzwa "zingazwa" ukuthi izindonga zemithambo yegazi zinwebeke kangakanani.

Lo mlayezo uya ngqo ebuchosheni bakho. Ubuchopho buchaza lokhu ngokuthi, "O, umfutho wegazi lakho usezingeni elihle."

Kodwa-ke, uma ukucindezeleka kulezi zindonga zemithambo yegazi kwehla, okusho ukuthi umfutho wegazi uphansi, ubuchopho benza okudingekayo ukuze kwandiswe umfutho wegazi ngokufanele.

Manje, kwenzekani uma usukuma ngokuzumayo? Amandla adonsela phansi abangela ukuba igazi elithile lihambe liye emilenzeni yakho. Bese inani legazi eliya ekhanda lakho liyancipha okwesikhashana. Kuleli qophelo, lawo ma-baroreceptors ezwa ukuthi izindonga zemithambo yegazi azinwebeki kahle. Uma lo myalezo uya ebuchosheni, ubuchopho buyaqonda ukuthi, "Kulungile, umfutho wegazi ubonakala uphansi." Bese ubuchopho butshela imithambo yegazi ukuthi "iqine kancane." Bese umfutho wegazi ubuyela esimweni esijwayelekile. Lena enye indlela imizimba yethu elawula ngayo umfutho wegazi.

Akukhona lokho kuphela, kodwa imizimba yethu ingalungisa nokushaya kwenhliziyo yakho, ukuthi imisipha yenhliziyo yakho iqina kangakanani, nokuthi inhliziyo yakho iphampa igazi elingakanani ngokusekelwe ekwehleni komfutho wegazi okwenziwa yilaba baroreceptors . Akumangalisi yini lokho?

Kwenzekani emzimbeni ngalokhu (i-Baroreceptor Reflex)?

Lezi zinzwa, ezibizwa ngokuthi ama-baroreceptors, zihlala ziqapha inani legazi emithanjeni yakho yegazi kanye nomfutho ongaphakathi kwayo. Uma umfutho wegazi wakho udinga ukushintsha, lawa ma-baroreceptorsItshela ubuchopho ukuthi kunjalo. Ubuchopho bube sebuthumela izimpawu enhliziyweni yakho nasemithanjeni yegazi ukuze kuthathwe izinyathelo ezidingekayo zokwehlisa noma ukuphakamisa umfutho wegazi lakho.

Kungaziphi izikhathi lapho lokhu (i-Baroreceptor Reflex) kusebenza khona?

Le baroreceptor reflex ingenziwa isebenze noma nini lapho umfutho wegazi lomzimba wakho ushintsha. Isibonelo:

• Uma ushintsha indawo yakho: ikakhulukazi uma uvuka lapho uhleli noma ulele phansi.
• Uma ubona into eyesabekayo noma uhlangabezana nesenzakalo: Cabanga ngokuzumayo uxoshwa yinja!
• Uma uqala ukugijima ngokuzumayo ekuhambeni: Uma ushintsha umsebenzi womzimba.

Kukuphi emzimbeni lokhu (i-Baroreceptor Reflex)?

Le baroreceptor reflex ayinayo indawo eyodwa ephakathi. Iyisistimu esebenza ndawonye ezingxenyeni eziningana zomzimba wethu.

Eyakho:

• Enhliziyweni
• Emithanjeni yegazi eyinhloko entanyeni (imithambo ye-carotid)
• Ngaphakathi kwamaphaphu

Kukhona lezi zinzwa ezibizwa ngokuthi ama-baroreceptors . Ulwazi oluvela kulezi zindawo luya ebuchosheni, futhi kusukela lapho imiyalelo edingekayo idlula ezicutshini zezinzwa kuwo wonke umzimba.

Yiziphi izingxenye eziyinhloko ze-Baroreceptor Reflex?

Le reflex ye-baroreceptor ihilela amangqamuzana ezinzwa (ama-neurons) kanye nemicu yezinzwa (imicu yezinzwa) ethwala imiyalezo mayelana nomfutho wegazi lakho. Ihilela nenhliziyo kanye nohlelo lokujikeleza kwegazi (uhlelo lwenhliziyo), oluthola leyo miyalezo futhi lwenze ngokufanele.

Kukhona ikakhulukazi lezi zingxenye:

• Ama-baroreceptor atholakala emithanjeni ye-carotid entanyeni yakho kanye nase-aortic arch (ingxenye egobile yomthambo wegazi omkhulu oqala enhliziyweni).
• Ama-baroreceptors atholakala emakamelweni enhliziyo yakho kanye nasemithanjeni yegazi emaphashini akho.
• Imizwa Yekhanda (imizwa ekhethekile exhuma ngqo ebuchosheni).
• `Isistimu Yezinzwa Ene-Parasympathetic` (isistimu yezinzwa ezola futhi ephumuza umzimba).
• Uhlelo Lwezinzwa Oluzwelana (uhlelo lwezinzwa oluvuselela umzimba, oluhilelekile empendulweni "yokulwa noma yokubaleka").
• Ama-arterioles (imithambo yegazi emincane kakhulu).

Yiziphi izifo ezithinta ukusebenza kwe-Baroreceptor Reflex?

Ezinye izimo zezokwelapha zingabangela ukuthi i-baroreceptor reflex ingasebenzi kahle. Ezinye zalezi zimo zifaka:

• 'Isifo sikaParkinson'
• `I-Broken Heart Syndrome` noma `I-Stress Cardiomyopathy` (isimo esithinta inhliziyo ngenxa yokucindezeleka okukhulu)
• Ukulimala Kwentambo Yomgogodla
• `Isifo Sikashukela (Uhlobo 1 noma Uhlobo 2 Lwesifo Sikashukela)`
• I-Postural Orthostatic Tachycardia Syndrome (i-POTS) (isimo lapho izinga lokushaya kwenhliziyo likhuphuka ngokushesha lapho kushintsha indawo)
• I-Lewy Body Dementia (isifo sengqondo esithinta inkumbulo kanye nokusebenza komzimba)

Futhi, lezi zinzwa ze-baroreceptor zingonakaliswa yizimila entanyeni noma entanyeni.

Yiziphi izimpawu ezingaba khona uma i-Baroreceptor Reflex ingasebenzi kahle?

Uma umsebenzi walesi sigaba se-baroreceptor uphazamisekile, izimpawu ezifana nalezi:

• Umfutho wegazi ongazinzile (ukungakwazi ukugcina izinga elihlala linjalo).
• Ukuntuleka kwegazi ezingxenyeni zomzimba.
• I-Tachycardia (ukwanda kwenhliziyo okungahlosiwe).
• Ukungakwazi ukukhulisa izinga lokushaya kwenhliziyo ngokunembile uma kudingeka.

Yiziphi izivivinyo ezenziwayo ukuhlola isimo sempilo se-Baroreceptor Reflex?

Odokotela bangenza izivivinyo ezinjengalezi ukuze babone ukuthi i-baroreceptor reflex yakho isebenza kahle kangakanani:

• Ukuqapha umfutho wegazi: Kungase kudingeke ukuthi ube nokuqapha umfutho wegazi ohambahambayo amahora angama-24.
• Ukulinganisa izinga lokushaya kwenhliziyo.
• `Indlela Yokwenza I-Valsalva`: Lokhu kuhilela ukubamba umoya wakho nokwenza ukucindezela okuqinile. Ngaleso sikhathi, umfutho wegazi kanye nokushaya kwenhliziyo kuyaqashelwa.
• Ukuhlolwa kwegazi.

Yiziphi izindlela zokwelapha izifo ze-Baroreceptor Reflex?

Uma kukhona amaphutha ekusebenzeni kwe -baroreceptor reflex , odokotela bangase banikeze imithi ethile. Kodwa khumbula, le mithi kufanele isetshenziswe kuphela njengoba kuyalelwe udokotela.

• `I-Midodrine`
• `I-Droxidopa`
• `I-Fludrocortisone`

Le mithi isiza ukulawula umfutho wegazi. Uma unale nkinga, kufanele nakanjani ukhulume nodokotela futhi uthole ukwelashwa.

Izinto ezilula esingazenza ukugcina i-Baroreceptor Reflex iphilile

Kunezinto ezimbalwa ongazenza ukusiza ukugcina umfutho wegazi wakho uzinzile, okuyikho lokhu kusabela kwe-baroreceptor . Khuluma nodokotela wakho ngalokhu:

• Ukudla ukudla okunempilo: Ukudla okunosawoti omncane, ushukela, namafutha, kanye nemifino nezithelo eziningi kuhle kakhulu.
• Uma izinkinga zomfutho wegazi zibangelwa imithi osuvele uyisebenzisa, ukushintsha imithamo yaleyo mithiKhuluma nodokotela wakho ngakho.
• Uma unesifo esihambisana nokungasebenzi kahle kwe-baroreflex , funa iseluleko sezokwelapha mayelana nokusebenzisa i-abdominal binder ukwandisa umfutho wegazi.
• Uma unalesi simo, thola futhi ugweme izinto ezingase ziphakamise noma zehlise umfutho wegazi lakho (bheka uhlu lwezimo ezingenhla). Isibonelo, ukuma ngokuzumayo noma ukuhlala endaweni efanayo isikhathi eside.

Okokugcina, into ebaluleke kakhulu okudingeka uyikhumbule!

Cishe uyaqonda ukuthi i-baroreceptor reflex iyisimiso esimangalisayo nesibalulekile emzimbeni wethu. Lolu hlelo lusebenza buthule, ngaphandle kokuthi wena uqaphele, ukugcina umfutho wegazi lakho usezingeni elijwayelekile lapho usukuma ngokuzumayo, uqala ukugijima, noma wesaba.

Into ebaluleke kakhulu ukuthi, uma uvame ukuzizwa unesiyezi, amehlo akho ephenduka aluhlaza okwesibhakabhaka, futhi uzizwa sengathi usuzoquleka, ungamane nje ukubheke njengento evamile. Ngokuqinisekile bonana nodokotela. Ngemuva kwalokho ungathola ukuthi yini ngempela ebangela lokhu bese uthola ukwelashwa uma kudingeka.

Nakekela umzimba wakho. Ngoba impilo iyinto ebaluleke kakhulu!

I- Baroreceptor Reflex, umfutho wegazi, isiyezi, isimiso sezinzwa, izinga lokushaya kwenhliziyo, impilo
