Lepheo flaps: sebopeho le litšobotsi tse

The phetoho ya di-valve pelo e telele hapa tlhokomelo ea bafuputsi ba. Tlōlo ea mosebetsi architectonic kapa karolo leha e le efe ea ka didirisiwa e phunyang isang kgoreletsego zakryvatelnoy belofo mosebetsi le pompa mosebetsi oa pelo ka kakaretso.

Melao-motheo e akaretsang ea sebōpeho sa septa atrioventricular

Lepheo flaps di na le dipegelo fibrous lesale uputsa samjun le mesifa papillary.

Belofo lesale ke fibrous foromo le kenyeletso ea lisele mesifa, tse mo lekgotleng tlotsitsoeng endocardium. belofo flaps li koahetsoe ke endothelium, 'me ho ba le sebopeho sa mekhahlelo.

Ka tataiso e tsoang ka atrial ho ventricular lera holim 3 teng:

1. Spongy.
2. Fibrotic.
3. Ventricular.

Motheong oa leqhama fibrous poleiti eo tsoa annulus fibrosus.

Lepheo flaps, kapa ho ena bona lera spongy, moqotetsane, o na le e ngata likhoele rekere e dinama tse nyenyane tse connective, e haholo-holo ba bua ka bohale ntle le uputsa ka. likhoele batlang e le kholoanyane ho rekere ka mahlaku a ea phunyang serurubele, tricuspid feta.

Lera ventricular collagen likhoele ho rena.

belofo holim

Lepheo flaps na bokaholimo tse peli - atrial le ventricular, le metshetshe tse peli - e tsitsitseng le mahala.

Sebakeng atrioventricular valve lipelong tsa batho ho feta sebaka sa di-valve ka makala e tšehali. Tricuspid belofo bivalve sebakeng e khōloanyane ka ho hoo e ka bang 25%.

mesifa Papillary le chord tendon bopa pelo ea sethusathuto subvalvular. Samjun khomaretse mapheo. Bolelele le botenya ba tsona e fihla lebetsoeng le lona lilemong 35-40.

belofo serurubele

Palo ea lipampiri (mahlaku a) ho tloha 2 ho 6. Root:

• ka pele, 'me hangata feela, ka linako tse ling arotsoe ka likarolo tse peli;
• ka morao.

Ba kamehla e kholo.

The uputsa pel'a sebopeho kgutlotharo, o khomaretse e ka holimo-sa boraro sa ho medial, kamorao ho setseng itse phunyang, e na le sebopeho ya khutlonnetsepa. Bobeli ba le boreleli basal le apical libaka kaba arohantsoe ke Crest ka.

The lobe ka pele ea phunyang mitral ho latela tshebetso e ea motheo, e le ho feta mobile, nakong systole, boikarabello bakeng sa mojaro khōlō, ha a ntse a liphihlelo tse ngata tsa khatello ea mali tsoibitsoe ke ventricle ena.

Ka morao sa ameha ho koaloa phunyang le. Se boleloang ke tshebetso ya ho tse nyenyane.
Uputsa valve chord ba tsitsitseng ho mesifa papillary.

Tendon samjun:

• lohiloeng ka lehlakoreng ventricular ea phunyang libakeng batallang, e mong le e aroha dikgwele tharo thinner.

Ho lobe ka pele, e leng o na le uputsa belofo 2, ke papillary mesifa khomaretse 5-10 samjun, ho ka morao ho - 10-20, 20-30 ka linako tse ling tendon likhoele.

Ka ho le letšehali ventricular atrio-lesoba ka annulus fibrosus na le sebopeho hanyenyane oval.

3 lehare damper

Mabapi le palo ea mapheo (lobes) le boholo ba tsona ho sebopehong sena, e le ha ho na tumellano. Ho nkoa hore e entsoe ka 3 palo e fapaneng ya flaps le likarolo lipakeng kapa di-valve. Ka lilemo, palo ea lobes ea eketseha ka lebaka la petsoha lipoleiti tse khōlō ka nyenyane.

The flaps sa tokelo valve atrio-ventricular ke lefahla endocardium hore meleng e ka atrium nepahetseng le ventricle.

The ventricle nepahetseng, ka ho latellana flaps 3 hangata e na le lihlopha tse tharo tsa mesifa papillary. Li simoloha ho tloha ventricle nepahetseng (Front - matla ka ho fetisisa, 'me joale khutlela septal). palo ea mesifa tsena, boholo le sebōpeho sa batho ba tšoanang. E mong le e papillary mesifa samjun romela 2-4, eo, branching, ba khomaretse holim tlase le molekeng oa lipampiri e phunyang. Nyenyane lipakeng flaps khomaretse leboteng ventricular.

Pelo ea phunyang ho etsa lipatlisiso ke motheo motheo.

Lilemong tse fetileng tsa clarifying lipotso mali phepelo valve le ontogeny bona.

Kahoo, sehloohong sena le potso mabapi le sebōpeho sa di-valve pelo, ho akarelletsa le bi- le hut. Tlhahisoleseding ena e tla ba molemo ho baithuti ya ditheo tsa bongaka, hammoho le ba neng ba feela batla ho etsa lintho ka ikhethang, ena. Ho feta moo, liithuti ithuta baeloji 'me o human anatomy, tlhahisoleseding e mabapi le seo lepheo la di-valve pelo, e tla boela ho be le e thahasellisang haholo.
