Paub tab cov qe ntshav liab ( RBCs ) ua tsis muaj cev nrog rau lwm lub cell organelles xws li mitochondria, Golgi apparatus thiab endoplasmic reticulum txhawm rau txhawm rau kom muaj ntau dua ntawm hemoglobin hauv cov hlwb. Txawm li cas los xij, cov qe ntshav liab tsis paub qab hau muaj cov nucleus.
Ib yam li ntawd, tib neeg nug, vim li cas cov qe ntshav liab tsis muaj cov nucleus?
Qhov tsis muaj ib cev yog kev hloov pauv ntawm ntshav liab rau nws lub luag haujlwm. Nws tso cai rau cov ntshav liab kom muaj ntau hemoglobin thiab, yog li ntawd, nqa oxygen molecules ntau dua. Nws tseem tso cai rau ntawm tes kom muaj nws qhov tshwj xeeb bi-concave zoo uas pab cuam tshuam.
Kuj Paub, yuav ua li cas tshwm sim rau lub nucleus ntawm cov qe ntshav liab? - Tsis zoo li lwm tus hlwb hauv koj lub cev, koj cov qe ntshav liab tsis muaj nuclei . Poob qhov cev enables cov ntshav liab kom muaj cov pa oxygen ntau nqa hemoglobin, yog li ua kom cov pa oxygen ntau tuaj thauj hauv ntshav thiab txhawb peb cov metabolism.
Xav txog qhov no, dab tsi yog cov qe ntshav liab tsis paub qab hau?
Reticulocytes yog cov qe ntshav liab tsis paub qab hau (RBCs). Hauv cov txheej txheem ntawm erythropoiesis ( ntshav liab tsim), reticulocytes tsim thiab paub tab hauv cov pob txha thiab tom qab ntawd nthuav tawm ib hnub nyob hauv ntshav kwj dej ua ntej yuav loj hlob tuaj cov qe ntshav liab.
Vim li cas kuv thiaj muaj cov qe ntshav liab nucleated?
Nquag, nucleated RBCs yog pom tsuas yog nyob rau hauv kev ncig ntawm fetuses thiab cov me nyuam yug tshiab. Yog li, yog tias NRBCs yog pom ntawm tus neeg laus lub peripheral ntshav smear, nws qhia tias muaj yog qhov kev thov siab heev rau cov pob txha pob txha los tsim RBCs, thiab tsis paub qab hau RBCs yog raug tso tawm rau hauv kev ncig.
