'ēheu puapua: ka 'ole a me nā' ano

Ke morphology o ka naau kiwikā o ua lōʻihi o Laielohelohe i ka noonoo ana o ka noiʻi. 'Aʻe' ana o ka architectonic hana paha i kekahi hapa o ka nohona kiwikā nakeke hele aku ai i ka hoʻohuikau 'zakryvatelnoy kiwikā papa, a me ka pumping ha awina o ka naʻau, e like me ka a pau.

Ke mau loina o ka 'ole o ka atrioventricular septa

'ēheu puapua hoʻohui pū fibrous komolima huʻa chord a me papillary nāʻiʻo.

Kiwikā o ke komo lima i fibrous palapala me ka hoʻi o ka Muscle keena, i mea i loko o kapa komo iā ia endocardium. e uhi kiwikā puapua ma ka endothelium, a i ka pona paʻa 'ole.

Ma ka olelo mai ka atrial a hiki i ka ventricularʻilikai 3 i koe:

1. A naele ia.
2. Fibrotic.
3. Ventricular.

Ke kumu o ke kāʻei fibrous una i hele mai, mai ka annulus fibrosus.

Eheu puapua, a he oiaio, ua lākou a naele, ahu iho, ololi, i ka hailona o laholio olona, ma ka connective'aʻaʻa, a uaʻano nui hoʻomōhala ma ka noa kae o ka puapua. KŘpa a oi aku laholio olona, ma ka petals o ka hahai kiwikā, tricuspid ma mua.

Ke ahu iho ventricular collagen olona, predominate.

'ilikai kiwikā o

'ēheu puapua i mau surfaces - atrial a me ka ventricular, a me ka oi lua, penei - paa a me ka ole.

Ka wahi o ka atrioventricular kiwikā o na kanaka i ka naau hou ma mua o ka wahi o ka nohona kiwikā i loko o ka wahine nā loko. Tricuspid kiwikā bivalve nui ma ka hola 25% wahi.

Papillary nāʻiʻo a me tendon chords nāna i hana i ka naau o subvalvular i hoʻomākaukauʻia. Chord pili i nā'ēheu. Ka lōʻihi a me ka mānoanoa o ka ihoiho kona i kā mākou i loko o 35-40 makahiki.

hahai kiwikā o

Ka helu o nā leaflets (petals) i mai ka 2 a hiki i 6. lālā:

• mua, pinepine wale, i kekahi manawa, i nā'āpanaʻelua;
• hope.

Ka mea, e mau ana nui.

Ka mua huʻa o ka triangular kinona, ua pili i ka luna-hapakolu o ka medial, posterior i ke koena o ka la kiwikā o, ka mea, i kekahi mau huinahń shape. Elua i ka malimali a me ka basal apical apuupuu cii hoʻokaʻawaleʻia ma ka lapa.

Ka mua lobe o ka mitral kiwikā i loko o ooieoeiiaeuiuo hua'ōlelo ka walaʻauʻana, ka mea i oi mobile, i systole, helu mahina no ka papa kuhikuhiE haawe ana, e like me ia i hanaʻia me ka bulk o ka manaʻo koikoi o ke koko kipaku ia e ka ventricle.

Hope komo hou i loko o ka panina o ka nohona kiwikā. Ke ooieoeiiaeuiiai manaʻo nui o ka mea uuku.
Puapua kiwikā chords i paa i ka papillary nāʻiʻo.

Tendon chord:

• ulana i kaʻaoʻao ventricular o ka nohona kiwikā i loko o apuupuu wahi, kēlā Wāwahi i loko o ekolu thinner pae.

I ka mea mua lobe, a i ka puapua kiwikā 2, ma ka papillary nāʻiʻo i pili 5-10 chord, a hiki i ka hope - 10-20, 20-30 i kekahi manawa tendon olona.

Haʻalele ventricular atrio-hole ma ka annulus fibrosus mai he iki ka'ololaha shape.

3 ke kōmi 'damper

Me ka pili ana i ka helu o nā'ēheu (lobes) a me kā lākou nui i loko o kēia 'ole, e like me ka mea, aohe kona manaʻo ma. Ua Ua noʻonoʻo i ka mea, ua haku o 3 'okoʻa ka helu o ka puapua, a waena Hoʻohana paha kiwikā. Me makahiki, ua hoonuiia ka helu o lobes aie a hiki i ka splitting o na kumu papa i loko o uuku.

Ka puapua o ka akau atrio-ventricular kiwikā iʻia kekahi mau mea endocardium i laina i ka atrium akau a me ka ventricle.

Ka'ākau ventricle, niioaaonoaaiii puapua 3 IeAUPIIe, IAa IO iʻekolu pūʻulu o papillary nāʻiʻo. Ka mea, originate mai ka ventricle akau (Front - ka loa ikaika, a laila, hoʻi septal). Ka helu o kēia nāʻiʻo, i ka nui a me ke kinona i ole i ia kanaka. Kēlā me papillary Muscle chord hoouna 2-4, a, ai manamana ai, e pili ana i ka lalo ili, a me nā kihi o ka nohona kiwikā leaflets. Small waena puapua pili i ka ventricular paia.

Heart kiwikā noiʻi o ke kahua kulanui.

Ka hope makahiki o clarifying nīnau koko lako nohona kiwikā a me kā lākou ontogeny.

Pela, i loko o kēia 'atikala i ka ninau e pili ana i ka' ole o ka naʻau kiwikā, me bi- a me ka Tri. Kēia 'ike E e pono i nā haumāna o ka' inikua kulanui, e like me ka pono me ka poe i wale makemake e hana ma luna o kēia hana kūikawā. A, nā haumāna e hoʻopaʻa haʻawina i ka kālaimeaola a me ka'anatomia, 'ike e pili ana i ka'ēheu o ka naau kiwikā, e kekahi e loa hana hoihoi.
