Kuj nug tias, Kupffer hlwb ua haujlwm li cas?

Kupffer Cells Lub luag haujlwm ntawm cov cell no suav nrog phagocytosis ntawm cov khoom loj, tso tawm ntawm cov neeg nruab nrab-kev tswj hwm kev tiv thaiv kab mob, thiab kev hu nkauj ntawm kev sib koom tes hauv lub daim siab nyob rau hauv cov nqe lus ntawm microcirculation thiab kev tiv thaiv ntawm hepatocytes.

pom hepatocytes nyob qhov twg? Hepatocyte . A hepatocyte cov yog lub cell ntawm cov ntaub so ntswg parenchymal tseem ceeb ntawm daim siab. Hepatocytes ua 55-65% ntawm lub siab lub cev.
