Kev puas tsuaj ntawm tes tuaj yeem thim rov qab lossis hloov tsis tau. Nyob ntawm seb qhov twg raug mob , cov cellular cov lus teb yuav hloov tau thiab qhov twg ua tau, homeostasis rov qab los.
Tom qab ntawd, lo lus nug yog, cov hlwb teb li cas rau kev raug mob? Xov tooj kev puas tsuaj ua rau mob hnyav lus teb uas xaus nrog kho kom puas hlwb /cov ntaub so ntswg, thiab yog ib feem ntawm lub cev tsis muaj zog lus teb . Ua raws raug mob , qhov puas endothelium tso tawm cov kws kho nruab nrab thiab ua rau cov ntshav khov. IR thiab cov endothelium puas ua haujlwm ua ke.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas cell raug mob?
Cell raug mob . Cell puas tuaj yeem tshwm sim raws li qhov tshwm sim ntawm kev cuam tshuam tsis zoo uas cuam tshuam qhov qub homeostasis ntawm cuam tshuam hlwb . Ntawm lwm qhov ua rau qhov no ua tau yog vim lub cev, tshuaj lom neeg, kis kab mob, lom neeg, khoom noj khoom haus lossis kab mob tiv thaiv kab mob.

Cov kev raug mob no feem ntau tshwm sim rau cov kabmob hauv lub cev-lub suab, lub ntsws, thiab lub plab zom mov
Kev sib raug zoo ntawm kev loj hlob ntawm tes thiab kev tsim tawm ntawm tes yog dab tsi?
Thaum lub sij hawm Binary fission thiab mitosis theej tawm cov DNA cov ntsiab lus ntawm kev tsim cov niam txiv ntawm tes tau muab cais ua ob qhov sib npaug sib luag uas yog lub hom phiaj kom xaus rau hauv ob tus ntxhais ntxhais. Ib feem kawg ntawm cov txheej txheem ntawm kev tsim cov cell yog faib cell, thaum tus ntxhais lub cev lub cev sib cais los ntawm niam txiv ntawm tes
Dab tsi yog cov txheej txheem feem ntau ntawm kev raug mob rau lub ncauj tsev menyuam raug mob hnyav?
