Yog li ntawd, dab tsi yog lub luag haujlwm ntawm lub ntsws hauv cov hlab ntshav?

Cov lub ntsws 'lub ntsiab luag hauj lwm yog nqa tawm hauv huab cua los ntawm huab cua thiab kis oxygen mus rau hauv cov hlab ntsha. Los ntawm qhov ntawd, nws nthuav mus rau tag nrho lub cev.

Qhov thib ob, txoj kev ncig ua haujlwm zoo li cas? Cov circulatory system yog tsim los ntawm cov hlab ntshav uas nqa ntshav tawm ntawm thiab mus rau lub plawv.
