Ntshav capillary yog tau los ntawm cov hlab ntsha txaj tas muaj ntawm cov hlab ntsha me tshaj plaws (venules) thiab cov hlab ntsha (arterioles) ntawm cov hlab ntshav. Cov venules thiab cov hlab ntshav sib koom ua ke cov hlab ntsha txaj tsim kev sib xyaw ntawm cov hlab ntsha thiab cov hlab ntsha ntshav.

Tsuas yog li ntawd, qhov muaj pes tsawg leeg ntawm cov ntshav capillary yog dab tsi?

Ntshav capillary yog kev sib xyaw ntawm cov hlab ntsha thiab cov leeg ntshav ntshav . Los ntawm sab xis ntawm lub plawv los ntawm lub ntsws, oxygenated arterial ntshav ntws mus rau hauv cov hlab ntsha . Muaj, cov pa oxygen thiab cov as -ham raug faib thiab sib pauv rau carbon dioxide.

Ib yam li ntawd, capillary los ntshav yog dab tsi? Capillary los ntshav yog feem ntau hom sab nrauv los ntshav thiab qhov raug mob me tshaj plaws. Qhov no tshwm sim thaum cov hlab ntsha ua puas thiab los ntshav tshwm sim. Hom no los ntshav yog me, thiab ntshav lub nkoj tuaj yeem khov thiab nres qhov los ntshav los ntawm nws tus kheej. Venous los ntshav tshwm sim thaum cov hlab ntsha puas.

Thiaj li, qhov sib txawv ntawm cov ntshav venous thiab cov ntshav capillary yog dab tsi?

Nws paub zoo tias ntshav capillary muaj ntau dua hemoglobin (Hb) thiab hematocrit (Hct) qhov tseem ceeb tshaj cov ntshav . Hauv txhua pawg, venous platelet suav tau ntau dua li qhov sib thooj cov hlab ntsha tus nqi.

Dab tsi yog capillaries?

Kev txhais lus ntawm Capillaries ntawm cov hlab ntsha : Capillaries yog cov hlab ntsha me tshaj plaws. Lawv ua haujlwm faib cov pa oxygen los ntawm cov hlab ntsha mus rau cov nqaij ntawm lub cev thiab pub cov ntshav deoxygenated los ntawm cov ntaub so ntswg rov qab rau hauv cov leeg.
