Bapiro ichibhabhamisa: marongerwo unhu

The Morphology zviri mumwoyo mavharuvhu kare Akakwezva nevatsvakurudzi. Kutyora architectonic basa kana chikamu vharuvhu midziyo kunotungamirira Kuvhiringidza zakryvatelnoy vharafu kushanda uye kupomba basa mwoyo rose.

Mukuru Misimboti maumbirwo atrioventricular septa

Bapiro ichibhabhamisa vanoumba fibrous mhete kurova-rova Chord uye papillary tsandanyama.

Valve mhete muri fibrous chimiro pamwe kwebasa rinofanira tsandanyama masero, izvo nechomukati zvemapuranga endocardium. vharafu ichibhabhamisa vari nokufukidzwa endothelium, uye vane layered yakarongeka.

Nenzira kubva atrial kusvika ventricular pamusoro rukoko 3 iripo:

1. Chirambe chakapfava.
2. Fibrotic.
3. Ventricular.

Hwaro mucheka fibrous ndiro iyo chinobva annulus fibrosus.

Bapiro ichibhabhamisa, kana pane chirambe chakapfava dzavo layer yakatetepa, ane yakawanda kwakavharwa nenyama fibers ari connective zvinyama, iyo kazhinji nezvezvandaifanira vakasununguka pamuuyo kurova-rova. Tichishandisa zvikuru kwakavharwa nenyama fibers ari petals pamusoro shavishavi vharafu, tricuspid kupfuura.

The rukoko ventricular collagen fibers vakawanda.

pamusoro vharafu

Bapiro ichibhabhamisa vane hukawanika maviri - atrial uye ventricular, uye miviri yehombodo - wakaiswa uye wakasununguka.

Nzvimbo atrioventricular mavharuvhu mwoyo yevanhu kupfuura nzvimbo mavharuvhu ari munhukadzi zvomukati. Tricuspid vharafu bivalve nharaunda mukuru anenge 25%.

Papillary tsandanyama vane mudzira chords or the vanoumba mwoyo subvalvular midziyo. Chord dzakabatana mapapiro. Kureba uye ukobvu vavo kunosvika kunonyanyisa yaro muna 35-40 makore.

shavishavi vharafu

Number mapepa (petals) ane kubva 2 kusvika 6. Root:

• mberi, kazhinji oga, dzimwe nguva muzvikamu zviviri;
• rwemberi.

Vanogara guru.

The kurova-rova pamberi mativi chimiro, wanamatira rokumusoro-chetatu medial, posterior kuti chasara akati vharafu, ine rectangular chimiro. Vose vane kumeso basal uye apical mafungu zvikamu akaparadzaniswa pedyo penyika.

The pamberi akafukidza of mitral vharuvhu mu dzichipfekeka mashoko kunokosha, zvinonyanya Mobile, panguva systole, nekurangarira kuti huru mutoro, sezvo anosangana unorema kwokudzvinyirira ropa vabudiswa nokuda ventricle.

Rear yakareba munyaya pakazovharwa vharuvhu. The dzichipfekeka kukosha kwayo zviduku.
Anopapama mavharuvhu chords or the vari wakaiswa kuti papillary netsandanyama.

Mudzira nevaya:

• yakarukwa pamwechete ventricular divi vharuvhu munzvimbo ine nzvimbo, mumwe rwakakamukana wakawondereiko kudai mazuva ose shinda matatu.

Nechemberi akafukidza, iro rine kurova-rova vharafu 2, nokuda papillary tsandanyama zvakabatanidzwa 5-10 Chord, kuti shure - 10-20, 20-30 dzimwe nguva mudzira fibers.

Kusiyiwa ventricular atrio-gomba iri annulus fibrosus ane zvishoma denderedzwa chimiro.

3 chipande damper

Maererano nokuwanda mapapiro (lobes) uye avo kukura mune maumbirwo ichi, sezvo hapana tenderano. Zvinonzi vaiona kuti rinoumbwa 3 siyana uwandu ichibhabhamisa uye zvenguva zvikamu kana mavharuvhu. With zera, nhamba lobes ichiwedzerwa nokuda kukamurwa chikuru mahwendefa madiki.

The ichibhabhamisa rwerudyi atrio-ventricular mavharuvhu vari nouya endocardium kuti mitsetse zvakarurama atrium uye ventricle.

The rworudyi ventricle ukuwo ichibhabhamisa 3 kazhinji ane mapoka matatu papillary tsandanyama. Zvakatanga kubva kurudyi ventricle (Front - simba kupfuura, uye ipapo shure septal). Kuwanda tsandanyama idzi, kukura uye chimiro havasi zvakafanana vanhu. Mumwe papillary tsandanyama Chord anotumira 2-4, iyo, branching, vari kuda nechepasi nomumativi kumicheto vharuvhu mapepa. Small zvenguva ichibhabhamisa vasiyana ventricular madziro.

tsvakurudzo Heart vharafu ndiyo inokosha hwaro.

Okupedzisira makore kugadzirisa mibvunzo ropa rive mavharuvhu vavo ontogeny.

Saka, munyaya ino mubvunzo nemamiriro mwoyo mavharuvhu, kusanganisira ambodzidza uye saith. ruzivo urwu vachava kubatsira vadzidzi vezvokurapa masangano, uyewo vaya chete achida kuita dzakagadzirirwa ichi. Uyezve, vadzidzi vanodzidza nezvezvinhu zvipenyu anatomi, mashoko pamusoro chii bapiro mwoyo mavharuvhu, kuchavawo kunakidza chaizvo.
