Ropa rinotenderera nemuviri wese, richipa zvinovaka muviri kwese kwese uye kubvisa tsvina, saka inofanirwa kuchengetedzwa mumamiriro ezvinhu akajairika.Nekudaro, kana tsinga yeropa ikakuvadzwa uye ikatsemuka, muviri unoburitsa zvakatevedzana, kusanganisira vasoconstriction kuderedza kurasikirwa kweropa, platelet aggregation kuvhara ronda kuti rimise kubuda ropa, uye activation ye coagulation zvinhu kuti iite yakagadzikana thrombus kuvhara. kubuda kweropa uye Chinangwa chekugadzirisa tsinga yeropa ndiyo nzira yemuviri yehemostasis.

Naizvozvo, hemostatic effect yemuviri inogona kukamurwa kuita zvikamu zvitatu.Chikamu chekutanga chinobudiswa nekubatana pakati pemitsipa yeropa uye maplatelet, iyo inonzi primary hemostasis;chikamu chechipiri ndechekuita coagulation zvinhu, uye kuumbwa kwe reticulated coagulation fibrin, iyo inoputira maplatelet uye inova yakagadzikana thrombus, iyo inonzi yechipiri hemostasis, iyo yatinoti coagulation;zvisinei, apo ropa rinomira uye risingabudi kunze, rimwe dambudziko rinomuka mumuviri, kureva, mitsipa yeropa yakavharwa, iyo inokanganisa kugoverwa kweropa, saka chikamu chetatu chehemostasis ndiyo Kuparara kwe thrombus ndiko kuti. apo tsinga yeropa inobudirira mugumisiro wehemostasis uye kugadzirisa, iyo thrombus ichanyungudutswa kuti idzorere kufamba kwakanaka kwemudziyo weropa.

Zvinogona kuonekwa kuti coagulation chikamu chehemostasis.Hemostasis yemuviri yakaoma zvikuru.Inogona kuita kana muviri uchiida, uye kana ropa coagulation razadzisa chinangwa chayo, rinogona kunyungudutsa thrombus munguva yakakodzera uye kupora.Mitsipa yeropa haina kuvharwa kuitira kuti muviri ugone kushanda zvakanaka, ndicho chinangwa chakakosha chehemostasis.

Zvirwere zvinowanzoitika zvekubuda ropa zvinowira muzvikamu zviviri zvinotevera:

.

1. Vascular uye platelet abnormalities

Semuenzaniso: vasculitis kana pasi maplatelet, varwere vanowanzova nediki diki kubuda ropa mumucheto wezasi, iyo purpura.

.

2. Abnormal coagulation factor

Kusanganisira congenital hemophilia uye Wein-Weber's chirwere kana kuwana chiropa cirrhosis, muchetura wemakonzo, zvichingodaro, kazhinji pane hombe-yakakura ecchymosis makwapa pamuviri, kana yakadzika tsandanyama kubuda ropa.

Saka, kana uine kubuda ropa kusingawanzoitiki, unofanira kubvunza chiremba wehematologist nekukurumidza.
