Mapiko kutseka kuti uchiwo usatuluke: kapangidwe ndi makhalidwe

The kafukufuku wakapangidwe kazachilengedwe wa mavavu mtima kale chidwi ofufuza. Kuphwanya ntchito architectonic kapena mbali iliyonse ya zida valavu kumabweretsa kusokonezeka zakryvatelnoy vavu ntchito ndi ikukoka ntchito za mtima wonse.

Mfundo za kapangidwe ka septa atrioventricular

Mapiko kutseka kuti uchiwo usatuluke akupanga fibrous mphete khumudwitsidwa poyambira ndi minofu papillary.

Vavu mphete ali fibrous mawonekedwe ndi kulolerana maselo minofu, amene internally TACHIMATA endocardium. vavu kutseka kuti uchiwo usatuluke okutidwa ndi endothelium, ndipo ndi dongosolo magawo.

Mu malangizo ochokera ku matenda kwa yamitsempha yamagazi wosanjikiza pamwamba 3 alipo:

1. Chofewa ngati siponji.
2. Fibrotic.
3. Yamitsempha yamagazi.

Maziko a lamba wa pamimba fibrous mbale lomwe linachokera ku annulus fibrosus.

Mapiko kutseka kuti uchiwo usatuluke, kapena m'malo awo wosanjikiza chofewa ngati siponji, yopapatiza, ali kwambiri ulusi zotanuka mu minofu connective, zomwe zimagwiritsa lolunjika m'mphepete ufulu wa khumudwitsidwa ndi. ulusi Ndi wamkulu zotanuka mu pamakhala valavu Gulugufe, tricuspid kuposa.

Wosanjikiza yamitsempha yamagazi kolajeni ulusi amachuluka.

valavu pamwamba

Mapiko kutseka kuti uchiwo usatuluke ndi pamalo awiri - matenda ndi yamitsempha yamagazi, ndi mbali ziwiri - atathana ndi ufulu.

M'dera la atrioventricular mavavu mitima ya anthu oposa dera mavavu ziwalo chachikazi. Tricuspid vavu bivalve m'dera wamkulu ndi pafupifupi 25%.

minofu Papillary ndi makodi tendon kupanga mtima wa zida subvalvular. Poyambira Ufumuyo mapiko. M'litali ndi makulidwe a iwo ukufika pazipita yake m'zaka 35-40.

vavu gulugufe

Chiwerengero cha timapepala ta (pamakhala) ali ku 2 6. Muzu:

• kutsogolo, nthawi zambiri yekha, nthawi zina mbali ziwiri;
• kumbuyo.

Nthawi zonse zazikulu.

The khumudwitsidwa kutsogolo kwa mawonekedwe triangular, amamangiriridwa chapamwamba-lachitatu la medial, zapambuyo kuti yotsala ya anati valavu, ali mawonekedwe anayi. Onse ali yosalala woyambira ndi apical mabacteria akhakula ankasiyana Crest a.

The Lobe kutsogolo kwa vavu mitral mawu zinchito ndi zazikulu, ndi zambiri m'manja, pa systole, mlandu katundu waukulu, monga amakhala zambiri za kuthamanga magazi ejected ndi ventricle lapansi.

Kumbuyo yaitali nawo kutsekera valavu. Tanthauzo zinchito za izo ang'onoang'ono.
Khumudwitsidwa mavavu makodi ndi kuliika kwa minofu papillary.

Tendon poyambira:

• nsalu ndi mbali yamitsempha yamagazi wa valavu m'madera akhakula, aliyense unagawika ulusi atatu n'kakang'ono.

Kwa Lobe kutsogolo, amene ali khumudwitsidwa vavu 2, ndi papillary minofu Ufumuyo 5-10 poyambira, mmbuyo - 10-20, 20-30 zina tendon ulusi.

Kumanzere yamitsempha yamagazi atrio-dzenje pa annulus fibrosus ali ndi mawonekedwe pang'ono chowulungika.

3 tsamba damper

Poganizira chiwerengero cha mapiko (lobes) ndi kukula mu nyumba imeneyi, ngati palibe vutoli. Amaona kuti wapangidwa ndi 3 chiwerengero osiyana kutseka kuti uchiwo usatuluke ndi zigawo wapakatikati kapena zingwe. Ndi zaka, chiwerengero cha lobes ndi chinawonjezeka chifukwa akuwaza mbale yaikulu mu ang'onoang'ono.

The kutseka kuti uchiwo usatuluke wa lamanja mavavu atrio-yamitsempha yamagazi ndi achibwereza endocardium kuti mizere atrium chabwino ndi ventricle.

The ventricle bwino, motero imakupiza 3 kawirikawiri amakhala magulu atatu a minofu papillary. Iwo ndi ochokera ku ventricle bwino (Front - amphamvu kwambiri, ndiyeno nkubwerera septal). chiwerengero cha minofu imeneyi, kukula ndi mawonekedwe sali anthu ofanana. Aliyense papillary minofu poyambira amatumiza 2-4, zomwe, nthambi, amagwira pamwamba pansi ndi m'mbali mwa timapepala ta valavu. Small wapakatikati kutseka kuti uchiwo usatuluke zaikidwa pakhoma yamitsempha yamagazi.

Mtima vavu kafukufuku ndi maziko ofunika.

Zaka zomalizira za kukambirana mafunso magazi okwanira mavavu ndi ontogeny awo.

Motero, m'nkhani ino ndi funso za kapangidwe ka mavavu mtima, kuphatikizapo anka- ndi Tri. Mfundozi akhala akugwira kwa ophunzira mabungwe zachipatala, komanso anthu amene okha akufuna kuchita zapaderazi izi. Komanso, ophunzira amene kuphunzira zamoyo ndi thunthu, nkhani zimene mapiko a mavavu mtima, kudzakhala chidwi kwambiri.
