Kutheni kukho ubunzima entliziyweni?

Intliziyo lomntu ilungu dystrophy ukuba nemilinganiselo malunga kungengqindi umntu lowo engeyakhe. ubunzima umzimba ngumlinganiselo grams 300 amadoda kunye 250 grams - kwabasetyhini. Heart symmetrically yahlulwe kabini - ekhohlo ne ekunene. Ilungu ngalinye lenziwa amagumbi amabini. Egumbini eliphezulu - intendelezo - eyenzelwe yokuqokelela igazi. Egumbini elisezantsi kuthiwa ventricle, apho kukho izivalo owongozelelweyo eKFC ukuthintela sokuphuma igazi. Iindonga ngaphakathi ekudibaneni intliziyo iquka izihlunu entsonkothileyo sekhombuya, ebizwa ngokuba myocardium.

Eyona umsebenzi intliziyo - isetyhula ngentshukumo eqhubekekayo kwegazi wonke umzimba. Le pulses eziqala ngokuzenzekelayo ekuthotyweni ngokwakhe. Le impahla self-excitation inikwa ngumntu inkqubo conductive ibekwe ngaphakathi myocardium. Le nkqubo iyakwazi okuvelisa pulses zayo kwaye inika pulses zombane leyo abondliwayo ukusuka luvo. Onke la ewonke kunokubangela excitation nokurhwaqela le myocardium. Sami pulses kwenzeka kwenye yeendawo zentliziyo - in intendelezo ekunene. Bona ngenkani ukwenza kwamathumbu ezinesingqi.

Le Umzimba umthwalo kakhulu, kangangokuba bavame kwiimpembelelo ezahlukeneyo ezimbi. Kaninzi siva ubunzima esifubeni. Abanye ashaye ukucinga ukuba kubuhlungu ibele okanye esifubeni, kodwa yena intloko akezi, oko ubungqongqo kwentliziyo. Oku kuthetha ukuba kukho iingxaki kumsebenzi umzimba uphela okanye iimpahla yegazi, nto leyo Yek igazi entliziyweni. Zintoni izinto ezibangela intlungu, kutheni kukho sisingqala entliziyweni?

Kulo mzekelo, igazi, ngenxa yoko, odlisa ubomi nokubetha kwentliziyo, imvakalelo Ukuphelelwa, ubuhlungu. Kukho intlungu ngohlobo ukuntlontlozela emabeleni lasekhohlo, ebizwa ngokuba yi-imvakalelo 'lump emqaleni. " Ezi mpawu ezinxulumene nomsebenzi ngokwasemzimbeni kunye nezidubedube enomfutho.

2. Esinye isizathu sokuba imbonakalo womxhuzulane - hormone iingxaki. Babonakala ngokuqhelekileyo phambi okanye ngexesha esexesheni, xa umzimba ngokutsha hormone. Ngeli xesha, uya kufumana ukuhlatywa intlungu entliziyweni, kwandisa dude. ukulingana hormone kwabasetyhini ngexesha exesheni wakhiwa, kwaye ngeli xesha kukho sisingqala entliziyweni babonakaliswa sijongene nayo, ukuthunga kunye ukushukumisa ucinezelo. yesi wegazi ngeli thuba ingabangela ukuba ukusebenza ezingazinzanga kwaye zibe zikhulu.

3. Amaxesha amaninzi, iintlungu kunye ubunzima entliziyweni kwenzeka DYSTONIA nemithambo. Ezi namahlaba ezikumila ezahlukeneyo kwaye ezifana nesifo sentliziyo okanye angina. Kulo mzekelo, ukusetyenziswa nitroglycerin swi nga pfuna, kuba intlungu umzimba sinxulumana amandla omzimba.

4. echaphazela ngokungalunganga intliziyo jet lag, kunokuba ngenxa ebusuku, ukunqongophala usuku lokuphumla, utshintsho jet lag. Kwiimeko ezinjalo, neempahla intliziyo negazi imini nobusuku, uvavanyo umthwalo, emva koko vasospasm negazi xi suka zingenzeka. Ukuqalisa ungenakuwuxhalabela iintlungu ngokucindezela okanye wagwaza.

5. iyingozi kwaye ngokugqithiseleyo (rhoqo okanye ixesha elide) ukusetyenziswa iziselo ezinxilisayo. Utywala ungena egazini, nje imizuzu embalwa kunyusa nezihlandlo yindibanisela imisipha intliziyo, yandisa imveliso adrenaline. Ngenxa yoku, ukunyuka engabalulekanga oxygen imfuno, mvisiswano leyo, kwelinye icala, kwandisa intliziyo imfuneko igazi ngakumbi. Kukho ubunzima esifubeni, isingqisho intliziyo egxobhekile.
