Ntshav , Ib daim ntaub sib txuas

Muaj peb hom ntawm kev nyob hlwb nyob rau hauv ntshav : liab cov qe ntshav (los yog erythrocytes), dawb cov qe ntshav (los yog leukocytes) thiab platelets (los yog thrombocytes).

Ib sab ntawm qhov no, 3 hom qe ntshav yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?

Ntshav tau ua los ntawm cov ntshav feem ntau, tab sis 3 hom tseem ceeb ntawm cov ntshav xa mus nrog cov ntshav:

Platelets pab cov ntshav kom khov. Clotting nres cov ntshav los ntawm lub cev thaum cov hlab ntsha lossis cov hlab ntsha tawg.
Cov qe ntshav liab nqa oxygen.

Muaj pes tsawg hom qe ntshav nyob hauv tib neeg lub cev? Muaj peb leeg hom qe ntshav : liab cov qe ntshav , dawb cov qe ntshav , thiab platelets. Liab cov qe ntshav (RBCs) yog nyob deb ntawm ntau tshaj hom ntawm ntawm tes hauv tib neeg lub cev , suav rau ntau dua 80 feem pua ntawm txhua qhov hlwb . Neeg laus tib neeg muaj qhov chaw nyob ib ncig ntawm 25 trillion RBCs hauv lawv lub cev , ntawm qhov nruab nrab.

Ib yam li ntawd, koj tuaj yeem nug, hom cell twg muaj nyob hauv cov ntshav?

Cov hom loj ntawm cov qe ntshav suav nrog;

Cov qe ntshav liab (erythrocytes)
Cov qe ntshav dawb (leukocytes)
Platelets (thrombocytes)

7 hom qe ntshav yog dab tsi?

Ncua tseg nyob rau hauv cov dej plasma yog xya hom cell thiab cell fragments

cov qe ntshav liab (RBCs) lossis erythrocytes.
platelets los yog thrombocytes.
tsib hom qe ntshav dawb (WBCs) lossis leukocytes. Peb hom granulocytes. neutrophils. eosinophils ua. basophils. Ob hom leukocytes tsis muaj granules hauv lawv cov cytoplasm.
