Hemostasis cuam tshuam nrog peb theem pib cov kauj ruam : vascular spasm, kev tsim cov platelet plug, thiab coagulation , koj txhaws yam tseem ceeb txhawb kev tsim cov fibrin txhav . Fibrinolysis yog txheej txheem uas a txhav yog degraded nyob rau hauv lub nkoj kho. Anticoagulants yog cov tshuaj uas tawm tsam coagulation.
Ib yam li ntawd, koj yuav nug, cov txheej txheem ntshav khov yog dab tsi?
Coagulation, tseem hu ua txhaws , yog txheej txheem los ntawm qhov twg ntshav hloov los ntawm cov kua mus rau gel, tsim ua ntshav khov . Nws muaj peev xwm ua rau hemostasis, kev txiav tawm ntawm ntshav poob los ntawm lub nkoj puas, ua raws li kev kho.
Kuj Paub, dab tsi yog 12 yam ntawm cov ntshav khov? Cov hauv qab no yog cov coagulation yam thiab lawv cov npe sib xws:
- Factor I - fibrinogen.
- Factor II - prothrombin.
- Factor III - cov ntaub so ntswg thromboplastin (cov ntaub so ntswg)
- Factor IV - ionized calcium (Ca ++)
- Factor V - labile factor lossis proaccelerin.
- Factor VI - tsis tau tso cai.
- Factor VII - qhov ruaj khov lossis proconvertin.
Yooj yim li ntawd, tsib kauj ruam koom nrog hauv ntshav khov yog dab tsi?
Cov ntsiab lus hauv txheej no (5)
- KAUJ RUAM 1. VASCULAR PHASE- RAPID CONSTRICTION OF THE VESSEL TO DRERECE BLOOD FLOW.
- PHAB 2. PHATELET PHASE- PLATELETS CLUMP sib koom ua ke thiab nyob rau qhov raug mob VESSELS rau FORM PLUG thiab INHIBIT BLEEDING.
- PHAU 3.
- PHAB 4.
- PHAB 5.
Dab tsi ua rau cov ntshav khov ua?
Ua . Cov ntshav txhaws thaum qee qhov ntawm koj ntshav thicken, sib sau ua pawg semisolid. Cov txheej txheem no tuaj yeem ua rau raug mob lossis qee zaum tuaj yeem tshwm sim sab hauv ntshav cov hlab ntsha uas tsis muaj qhov raug mob pom tseeb.

Dab tsi yog cov kauj ruam hauv lub neej ntawm cov qe ntshav liab?
Lub neej voj voog. Tib neeg cov qe ntshav liab yog tsim los ntawm cov txheej txheem hu ua erythropoiesis, tsim los ntawm cov kab mob qia hlwb mus rau cov qe ntshav liab loj hlob hauv li 7 hnub. Thaum matured, nyob rau hauv ib tug noj qab nyob zoo cov hlwb no nyob rau hauv cov ntshav ncig li ntawm 100 mus rau 120 hnub (thiab 80 mus rau 90 hnub nyob rau hauv ib tug tag nrho cov me nyuam mos)
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
