Magazi amayendayenda m'thupi lonse, kupereka zakudya kulikonse ndikuchotsa zinyalala, choncho ziyenera kusamalidwa bwino.Komabe, mtsempha wamagazi ukavulala ndikusweka, thupi limatulutsa zinthu zingapo, kuphatikiza vasoconstriction kuti muchepetse kutayika kwa magazi, kuphatikizika kwa mapulateleti kuti atseke chilonda kuti asiye kutuluka, komanso kuyambitsa kwa coagulation factor kuti apange thrombus yokhazikika kuti atseke. kutuluka kwa magazi ndi cholinga chokonzanso mitsempha yamagazi ndi njira ya thupi yopangira hemostasis.

Chifukwa chake, mphamvu ya hemostatic ya thupi imatha kugawidwa m'magawo atatu.Gawo loyamba limapangidwa ndi kugwirizana pakati pa mitsempha ya magazi ndi mapulateleti, omwe amatchedwa primary hemostasis;gawo lachiwiri ndi kutsegula kwa coagulation zinthu, ndi mapangidwe reticulated coagulation fibrin, amene kukulunga mapulateleti ndi kukhala khola thrombus, amene amatchedwa yachiwiri hemostasis, chimene ife timachitcha coagulation;komabe, pamene magazi amasiya ndipo sakutuluka, vuto lina limabwera m'thupi, ndiko kuti, mitsempha ya magazi imatsekedwa, zomwe zidzakhudza magazi, choncho gawo lachitatu la hemostasis ndilo Kusungunuka kwa thrombus ndiko kuti. pamene chotengera cha magazi chimakwaniritsa zotsatira za hemostasis ndi kukonza, thrombus idzasungunuka kuti ibwezeretse kuyenda bwino kwa mitsempha ya magazi.

Zitha kuwoneka kuti coagulation kwenikweni ndi gawo la hemostasis.Kutaya magazi m'thupi kumakhala kovuta kwambiri.Ikhoza kuchitapo kanthu pamene thupi likufunikira, ndipo pamene kugunda kwa magazi kwakwaniritsa cholinga chake, kumatha kusungunula thrombus panthawi yoyenera ndikuchira.Mitsempha yamagazi imatsegulidwa kuti thupi lizigwira ntchito bwino, chomwe ndicho cholinga chofunikira cha hemostasis.

Matenda ochulukirachulukira otuluka magazi amagwera m'magulu awiri awa:

pa

1. Kusokonezeka kwa mitsempha ndi mapulateleti

Mwachitsanzo: vasculitis kapena mapulateleti otsika, odwala nthawi zambiri amakhala ndi mawanga ang'onoang'ono otaya magazi m'munsi, omwe ndi purpura.

pa

2. Chomwe chimayambitsa coagulation

Kuphatikizira kobadwa nako hemophilia ndi matenda a Wein-Weber kapena matenda a chiwindi, makoswe, ndi zina zambiri, nthawi zambiri pamakhala mawanga akuluakulu a ecchymosis pathupi, kapena kukha magazi kwambiri.

Choncho, ngati muli ndi magazi omwe ali pamwambawa, muyenera kukaonana ndi hematologist mwamsanga.
