Ropa rinotenderera mumuviri wese, richipa zvinovaka muviri kwese kwese uye richibvisa tsvina, saka rinofanira kuchengetedzwa mumamiriro ezvinhu akajairwa. Zvisinei, kana tsinga yeropa ikakuvara uye ikatsemuka, muviri unogadzira maitiro akasiyana-siyana, anosanganisira vasoconstriction kuderedza kurasikirwa neropa, platelet aggregation kudzivirira ronda kuti rimise kubuda ropa, uye kumutsa macoagulation factors kuti agadzire thrombus yakagadzikana kuti ivhare kubuda kweropa uye Chinangwa chekugadzirisa tsinga dzeropa inzira yemuviri yekubvisa ropa.

Saka, simba remuviri re hemostatic rinogona kupatsanurwa kuita zvikamu zvitatu. Chikamu chekutanga chinogadzirwa nekubatana kwetsinga dzeropa nemaplatelets, izvo zvinonzi primary hemostasis; chikamu chechipiri ndechekuita kuti coagulation factors dzishande, uye kuumbwa kwe reticulated coagulation fibrin, iyo inoputira maplatelets uye inova stable thrombus, iyo inonzi secondary hemostasis, iyo yatinodaidza kuti coagulation; zvisinei, kana ropa rikamira uye rikasabuda, rimwe dambudziko rinomuka mumuviri, kureva kuti, tsinga dzeropa dzinovharika, izvo zvinokanganisa kugoverwa kweropa, saka chikamu chechitatu che hemostasis. Mhedzisiro yekunyungudika kwe thrombus ndeyekuti kana tsinga yeropa yawana simba re hemostasis nekugadzirisa, thrombus inonyungudika kuti idzorere kuyerera kwakanaka kwetsinga yeropa.

Zvinogona kuonekwa kuti kuvharika kweropa chikamu che hemostasis. Kuvharika kweropa mumuviri kwakaoma zvikuru. Kunogona kushanda kana muviri wachida, uye kana kuvharika kweropa kwasvika pachinangwa charo, kunogona kunyungudutsa thrombus munguva yakakodzera uye kupora. Mitsipa yeropa inovhurwa kuitira kuti muviri ugone kushanda zvakanaka, inova ndiyo chinangwa chikuru che hemostasis.

Matambudziko ekubuda ropa anowanzoonekwa muzvikamu zviviri zvinotevera:

.

1. Kusashanda zvakanaka kwetsinga dzeropa neropa remuropa

Semuenzaniso: vasculitis kana maplatelet akaderera, varwere vanowanzova nemadonhwe madiki ekubuda ropa mumiviri yepasi, ayo ari purpura.

.

2. Chinhu chisina kujairika chekugwamba kweropa

Kusanganisira hemophilia yekuzvarwa nayo uye chirwere cheWein-Weber kana chirwere chechiropa chakatorwa, chepfu yemakonzo, nezvimwewo, kazhinji pane mavanga makuru e ecchymosis pamuviri, kana kubuda ropa kwakadzika mutsandanyama.

Saka, kana uine kubuda ropa kusingawanzoitiki kwataurwa pamusoro apa, unofanira kubvunza chiremba weropa nekukurumidza.
