Lymph Nodes vs Glands
Cov qog thiab cov qog ntshav qab zib yog cov qauv tseem ceeb hauv tib neeg lub cev. Cov qauv no pab tswj cov txheej txheem lom neeg thiab tswj kev tiv thaiv kab mob hauv lub cev. Cov qog feem ntau cuam tshuam nrog cov kab mob hauv lub cev, thiab cov qog nqaij hlav tsim cov khoom ntawm cov hlab ntsha (thaum cov qe ntshav).
Lymph Nodes
Lymph nodes (lossis cov qog qog ntshav qab zib) yog cov kab mob lymphatic, uas yog qhov tseem ceeb heev los tsim kom muaj kev tiv thaiv hauv lub cev. Lymph nodes, hauv paus, muaj cov qe ntshav dawb nrog rau cov lymphocytes thiab macrophages. Lymph node muaj cov taum zoo li tus qauv. Txhua lub qog muaj cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha thiab cov hlab ntsha uas muaj zog. Muaj cov ntaub so ntswg nyob ib ncig ntawm cov qog nqaij hlav uas txuas mus rau hauv cov node thiab faib nws mus rau hauv cov nodules. Cov nodules muaj macrophages thiab lymphocytes, thiab ntws ntawm lymph.
Lymph nodes tuaj yeem pom raws cov hlab ntsha loj dua.

Nkauj hmoob
Gland yog ib qho kev sau ntawm cov cell secretory, uas zais qee yam khoom hauv tib neeg lub cev. Muaj ob hom qog; cov qog nqaij hlav thiab cov qog tsis muaj qog.

• Lymph nodes tsim cov lymphocytes thiab lim cov qog ntshav, qhov qog tsim cov tshuaj hormones thiab lwm yam secretions.
• Lymph nodes muaj macrophages thiab lymphocytes thaum lub qog muaj cov qog hlwb.
• caj pas muaj ntau yam duab, whereas lymph nodes yog taum-puab.
• Cov qog muaj nyob thoob plaws lub cev, thaum cov qog ntshav qab zib pom tsuas yog nyob ntawm cov hlab ntsha loj dua.
• Lymph nodes tau o thaum cov khoom txawv teb chaws nkag mus rau hauv lub cev, tsis zoo li qog.
• Feem ntau, cov qog loj dua cov qog ntshav qab zib.
• Lymph nodes txuas nrog cov hlab ntsha lymphatic, tsis zoo li cov qog.
