Koj puas tau pom tias qee zaum ib ceg lossis caj npab o me ntsis? Los yog tias cov kua dej zoo li dej puv ib puag ncig qhov txhab? Txawm hais tias peb tsis xav txog nws ntau, ib lub network zoo kawg nkaus hauv peb lub cev tswj hwm cov no. Nws zoo li lub kaw lus ntws dej hauv ib lub nroog. Hnub no peb yuav tham txog ib qho ntawm cov khoom me tshaj plaws, tab sis tseem ceeb heev ntawm lub kaw lus ntawd. Ntawd yog Lymphatic Capillaries.
Hauv lus yooj yim, cov lymphatic capillaries no yog dab tsi?
Xav txog tias peb lub cev yog ib lub nroog loj. Cov hlab ntsha yog cov kev loj hauv lub nroog ntawd. Cov kev no yog qhov chaw uas cov pa oxygen thiab cov as-ham uas lub cev xav tau mus txhua qhov chaw. Tab sis thaum qhov no tshwm sim, cov kua dej tsis tsim nyog sib sau ua ke ntawm cov hlwb ntawm peb lub cev. Ib yam li dej sib sau ua ke ntawm cov kev thaum los nag.
Lub cev lymphatic yog lub cev uas tshem tawm tag nrho cov khib nyiab thiab ua kom lub cev huv si. Cov hlab ntsha lymphatic no yog cov kav dej me tshaj plaws hauv lub cev ntawd. Lawv me heev uas lawv loj li ib txoj plaub hau.
Txawm hais tias cov no zoo ib yam li cov hlab ntsha capillaries uas nqa ntshav, muaj qhov sib txawv loj heev.
- Cov hlab ntsha lymph muaj me ntsis loj dua hauv txoj kab uas hla.
- Lawv kaw rau ib kawg . Lawv tsis qhib rau ob kawg zoo li cov hlab ntsha.
- Qhov txawv loj tshaj plaws yog cov kua dej tuaj yeem nkag mus rau hauv cov raj no, tab sis thaum lawv nkag mus rau hauv lawm, lawv tsis tuaj yeem tawm mus dua.
Lub cev lymphatic no yog ib feem tseem ceeb heev ntawm peb lub cev tiv thaiv kab mob , lub cev uas tiv thaiv peb ntawm kab mob.
Cov raj me me no muab kev pabcuam dab tsi rau lub cev?
Lub luag haujlwm tseem ceeb ntawm cov hlab ntsha lymphatic yog kom tswj tau qhov sib npaug ntawm cov kua dej hauv peb lub cev.
Qhov chaw nyob ib puag ncig peb cov hlwb yeej ib txwm muaj cov kua dej uas hu ua interstitial fluid tawm ntawm cov hlab ntshav capillaries. Qhov no yog ib txwm muaj. Tab sis yog tias cov kua dej no raug tso cai sib sau ua ke, cov chaw ntawd yuav pib o. Peb hu qhov no ua o (edema) .
Qhov uas cov hlab ntsha lymphatic ua yog nqus cov kua ntxiv uas sib sau ua ke. Thaum cov kua no nkag mus rau hauv cov hlab ntsha lymphatic, peb hu nws ua lymph .
Hais yooj yim xwb, cov hlab ntsha lymphatic yog ib lub kaw lus ntawm cov kav dej me me uas tshem tawm cov "dej pov tseg" ntxiv uas sib sau ua ke ntawm cov hlwb ntawm peb lub cev.
Los ntawm kev tshem tawm cov kua dej ntau dhau thiab ntxiv rov qab rau hauv cov ntshav, lawv kuj pab kom peb cov ntshav siab thiab cov ntshav ntim rau hauv qib ib txwm muaj.
Okay, yog li qhov no ua haujlwm li cas?
Cov txheej txheem no zoo kawg nkaus. Cov phab ntsa ntawm cov hlab ntsha lymphatic yog tshwj xeeb heev. Cov hlwb sib tshooj ua ke, tsim cov mini-valves.
- Thaum lub zog ntawm cov kua dej ntawm cov cell nce ntxiv, cov qhov rooj me me no qhib thiab cov kua dej nkag mus rau hauv cov hlab ntsha.
- Thaum lub siab hauv cov hlab ntsha nce ntxiv, cov qhov rooj no yuav kaw cia. Yog li cov kua uas tau nkag mus rau hauv tsis tuaj yeem tawm mus dua.
Tom qab ntawd cov kua lymph no uas tau sau los no mus ncig.
1. Cov kua dej no los ntawm cov hlab ntsha lymphatic capillaries sib sau ua ke hauv cov hlab ntsha lymphatic loj dua me ntsis.
2. Raws txoj kev, cov kua no hla dhau cov chaw kuaj me me hu ua cov qog ntshav . Cov no nyob rau hauv cov chaw xws li peb lub caj dab, qhov tso, thiab qhov chaw mos. Cov chaw kuaj no lim cov khoom tsis xav tau xws li cov kab mob, cov kab mob me me, thiab cov qog nqaij hlav hauv cov kua.
3. Cov kua dej lymph uas tau lim lawm yuav sib sau ua ke rau hauv cov kav dej loj dua, feem ntau yog cov kav dej hauv siab .
4. Thaum kawg, cov kua dej ntshiab no rov qab mus rau hauv lub cev ncig ntshav los ntawm cov leeg ntshav loj hauv qab peb lub pob txha caj dab ( cov leeg ntshav subclavian ).
Peb lub cev tseem noj qab nyob zoo vim tias lub voj voog no tseem ua haujlwm.
Cov lymphatic capillaries nyob qhov twg hauv lub cev?
Cov raj me me no kis tau yuav luag txhua qhov chaw hauv peb lub cev, tab sis qee qhov chaw lawv tsis pom.
- Cov pob txha
- Pob txha mos
- Txheej epithelial ntawm daim tawv nqaij
Tsuas yog cov chaw no xwb, txhua lub cev muaj cov hlab ntsha lymphatic no ntawm cov ntaub so ntswg.
| Ib feem ntawm cov lymphatic capillary | Txoj haujlwm uas tab tom ua |
|---|---|
| Cov hlwb endothelial | Lub cell tseem ceeb uas ua rau phab ntsa capillary. Cov no quav ua ib ke los ua cov qhov rooj me me (mini-valves). |
