He aha mea i ka hana o ka naau o ka mea nui? Maoli ai, i ke koko holo. Ole ia, ina aole e hiki i ka papa loa ana i ke kino. Ka mea ike i ka naau hana mau holo - ka poe liilii, a me ka nui. Ka mua o kēia mau helu kuhi puke i loko o ka ventricle akau, a me kona hope o Nyos i loko o ka atrium hema. He mea kuleana no ka piha kinoea wehe aʻe i loko o nā alveoli o na ia maʻiʻaʻai. E pili ana i ka lua o ka mea waiwai 'ana i kumumanaʻo ana i ka nui p ÷ ai i loko o ka ventricle hema hoʻomaka a me ka welau, e like me oe e koho, ma ka atrium akau. He mea kuleana no ke koko o ole wale na ia maʻiʻaʻai akā, i nā nā loko. A pau keia ua maopopo hoʻokō me wale i ka olakino naau.

Nui i ua mai la oia no ka nohona kiwikā o, a ma luna o nā mea i ka hana ana o ka naau. Kā lākou hana pono e hala ole a me ka pono-hoʻonohonoho. No ka mea, o ka pumping hana o ka naau hilinaʻi nui kaʻoi loa ma ka nohona kiwikā, i kahi hookahi hana i ka pauʻano papa hana. Tricuspid wehe - a me ke koko ae i loko o ka ventricle akau, mai ke atrium. Once ka mea, ua piha i ke koko,ʻo nāʻiʻo ma lalo o ke kanawai o ka'aloʻahiʻa kiwikā pani. A laila, hiki ke hele mai i ke koko ma ka pulmonary kumu, a hiki aku i ka pulmonary kiwikā e wehe ma lalo o ke koko,, i maoli i ka contraction o ka ventricle akau wale. I ke koko e hele mai e hoʻi wale nō ina ka hamama mitral kiwikā. Log ma aorta pani ka aortic kiwikā, i he o ka ekolu eheu e hoohalike ai i keʻano o nā crescents. I ka wā o ka ventricle hema mea nanea wale - e ua pani, a no laila, i ke venous koko komo i ka atrium akau. Pela ia i hana a me ke koko holo. O ka holo ana, lehelehe hana nei nō loa lōʻihi, akā, ma ka mea e lawe wale i ka manawa. A hookeai o ko kakou naau.

Nā kūʻiʻo, ua like me ka ike

Ke 'ole a me ka oihana o keia kino e ole nui wale, e hana hoihoi nō ka mea. No ka laʻana,ʻaʻole mea ike i ke koko holo ua lawe mai ka hola 100.000 manawa no ka lā ma ke kaawale, o ke 100 000 kilomika! Amazingly, ia mea ia he lōʻihi i nā mea a pau i nā ipu a pau o ko mākou kino. A ina ua kamailio e pili ana i ka nui o na manawa o ka makahiki hoemiia ko kakou naau, alaila, he mea wale Astronomical na kii - oi ma mua o 34 miliona! A eia ka mea hope, o ka hopeʻikepili - no keia manawa wā o ka naau EII ni ekolu miliona nā lika o ke koko. He incredibly nui. No laila, inā e kahaha no e pili ana i ka 'ano o ke kuleana pili i ua hana ma ka naau, ua hiki ke olelo aku nei au no kaʻoiaʻiʻo - nui. A hana no keia gigantic hana. He waiwai i olelo ia i kekahi hou mea: ma luna o kekahi kaukahi ka ho'ēmiʻana i kēia dala o ka ikehu, a makemake e lawa, e hookiekie ae i ka kiekie o 1 mika i ka ukana i loko o 400 nā huna o ke kaupaonaʻana. A me keia e lawe i loko no o ka mea i ka naau mea ma maha, pana aku au i 15 wale pakeneka o ka nui o kona me ke koe ma kona hoʻolilo. Akā, inā i ka paakiki hana i ke kino hana,ʻo ia ka hāhai 35% o ka ikehu. I mea mākou naʻau, i ka 'ole a me ka mana o ka i mea maoli kūikawā a me nā hana.

Myocardium a me kona specificity

Hereʻoe ke'ōlelo i ka manawa lōʻihi, a hala loa ka hailona. E lawe, no ka laʻana, myocardial contractile keena. Ana i ka hana o ka naau, hiki ole akā, pili i ka noonoo ana, a me ka manawa. Ka mea i ka mea, i ai no na makahiki holo me ka noho. No ka mea, ua nui ia ka mea, i mau lako me ka lewa. Ka muli o ka oxygen, a me ka mahuaola he kūlana maikaʻiʻole i ka hana ana o na kanaka naau. Inā ka mea, e ole hana, na keena hoʻomaka i ka make, a me ka koke. Ma hope o nā mea a pau, ka mea hana i ke koe nō, a hiki e pono keia mau mea i loko o ia hihia. Life o cardiac keena - he relentless holo. A me ka Muscle i ua paʻa kūhohonu loa i ke koko, e starve. Ma hope o myocardial koko e hoopiha ana kona lua, 'aʻole eʻai. Oxygen ma a me ka mahuaola i nā mea a pau e hele ana ma na moku e holo ana mai ka aorta.

Ka mea, o kekahi o ka mea nui. A ka mea, o ka alternation o ka diastole a me ka systole o ka naau ventricles - ua alternately lākou hoʻomaha a me ka contraction. I ka hana diastole, na ventricles hoʻopiha i ke koko. Inā he mea systole, ka mea hele i ke koko i loko o ka pulmonary kumu, a me ka aorta, 'ole. E. Ma na arteries nui. Pehea la e hiki ai oe i hoomanao - kokoke i na ventricles i ka naau kiwikā, a nō ka keʻakeʻa nei e hoole i naholo kiki mai ai o ke koko a hiki i ka naʻau, mai ka artery. Ma hope o nā mea a pau i ke koko, ma mua e hoopiha mai ana i ka ventricles, hele ma na aa koko nui 'ana i loko o ka atrium. Ka ho'ēmiʻana - ka mea, ua mua ia e kekahi ventricular systole. Mākou ke olelo aku i ka atrium - ia mea heʻano o nā kākoʻo EII ni, kōkua i ka hoʻopiha i ka ventricles.

Ka mea, e kuleana no keʻano o ka pīhoihoi, e like me ia no kona wehe 'ia' ana i na keena o ka myocardium. No laila, e hōʻeleu i ka naau kōmi - i no ia mau hopena o ka haunaele ma ka iaea ooieoeiiaeuiiai eiiiiiaiou o na kanaka kikowaena kino.

Ka hopena o ka hoʻohuikau 'ana o ka naau

?? lelo pehea pono hoʻokō kanaka naʻau hana, e hilinaʻi nui no kona ola, ua mua ua oleloia. Eia naʻe, i kēia lā, he nui koʻu hoomanawanui ana'ku ia mai ka maʻi pili i ia kino. Ka mea, e 'Imi maʻi poʻeʻelemākule kanaka a me nā kūpuna. O ke kumu ho i ka mea i ka mea i olelo ia - keia kino ua hana 'ole-hooki ma ke ola, a me ia mea e kahaha ko oukou naau i ma hope o 50-60 makahiki o ke ana hana, oia loaʻa māluhiluhi. Akula nā meaʻekolu o ka elima kanaka make no i ka naau maʻi, kaʻoi loa naau ho'āhewa wale.

Ma ka maʻi, he ekolu nui pūʻulu o ka maʻi i aloha ia i ka ipu koko, kiwikā a me ka iwi lole. No ka laʻana, atherosclerosis - ka maʻi e loli ai i ka ipu naau. Ma ke ala, i ka loa, he pono ole maʻi. A naau ole, he nui loa ia e loli ai. More nui illnesses e e wahi Hope. Ke ae pā o ka maʻi moe i loko o ka 'aʻe' ana i kekahi hana o ka naau kiwikā.

A eia ka mea hope, ka mea e e hoʻomaopopo noonoo ana i ka 'aʻe, me he myocardial infarction. A oko o coronary artery maʻi - ka wā ma laila mea i ka maʻi o ka myocardium aina pohaku e omo i ke koko, a me ia mea,ʻaʻole like, pili like mau.

Ma muli o ka luna, ka mea hiki ke hoʻomaopopo i ina kekahi loli ana me mākou ka papa kuhikuhi kino - laila, i kēia mea maopopo leʻa i ka 'aʻe' ana o kekahi o ka kuleana pili i ka naau. Paha i ka maʻi loa, he pono ole, a ka hapanui pinepine malama ka naʻau palpitations.

Akā, i kekahi manawa, i kēia maʻi ua i pili me ka naau - ia paha e ukuia i ka thyroid maʻi, menopause aʻeho hoike aku ia ia iho. He nui nā kanaka wale mai i hoʻolohe i recurring ka eha, a me nā akua ka waiʻona ma ke. A me ka makehewa, no ka mea, o ko makou naau uaʻike piʻi i ka nui haawe ana. No lehulehu i keia, e ia ka hihia ina he malū haʻawina o nā i ka'emi hana, stress a me ka hokahoka.

Ma waho aʻeo ia i ka manaʻo o ka holo, keia nui kino, he mea'ē aʻe nā papaha. He aha ka mea, i ka papa kuhikuhiE mana o ka naau e e anao? Aou hou? Paha ka ai-kapaia automatism - kona hiki e paka i na lāʻau ikiʻai wale i hoʻonāukiuki excitation. Ka nui kekahi automatism sinoatrial wahi. Aka hiki ole hoopoina e pili ana i ka conductivity - i ka hana o ka myocardium, a he oiaio, ua kona hiki, e hoʻouna i impulses 'ana i loko o ka contractility o ka naau. Maoli, excitability - ke kaʻina hana ma ka hoʻolako 'kokololio Kal lāʻau ikiʻai wale ole. A, o ka papa, refractory, o ka nele o ka hiki, e haʻalele keena o ka myocardium pīhoihoi ma ka hihia ina ka mea, e mau no lepa i ka hoʻomaka 'ana e hiki. Ua Ua puunaueia e ka kāpae (ka wā o ka naau, ua pau loa ia apathetic i kekahi excitation), e like me ka pili (ke kino reacts a hiki i ka 'aoʻao o loa ikaika). No laila, na kanaka naau mana i ole.

Ka mea wale nō mea i aʻu i makemake makemake e hōʻike - no ka mea, mea e pono ai, e lawe mālama ana ia mea. Ma hope o nā mea a pau, o keia kino ka mea nui, a me ka mea hilinaʻi nui ma luna o ke ano o ka lōʻihi like 'ole o ke kanaka ola. Penei, ma muli o ka keia, ka mea, he pomaikai, e hai aku i ka naau 'ole a me ka hana o ka i i noʻonoʻo piha ano, - heʻano papa hana iloko olaila no ka nui o na moku koko, cavities a me ka nohona kiwikā, interconnected kekahi manao - e i ka piha holo.
