Cia peb kawm txog cov phab ej me me hauv koj lub cev - Lymphatic Capillaries.

Koj puas tau xav tias muaj pes tsawg yam zoo kawg nkaus tshwm sim hauv peb lub cev yam tsis tau peb paub? Hnub no peb yuav tham txog cov hlab ntsha lymphatic capillaries, lossis hauv lus Askiv '(Lymphatic Capillaries)', uas ua haujlwm ntsiag to rau peb zoo li cov phab ej me me. Tej zaum koj yuav tsis tau hnov ​​​​​​txog lub npe no, tab sis qhov kev pabcuam uas cov neeg no ua los ua kom peb lub cev noj qab haus huv yog qhov zoo kawg nkaus.

Cov hlab ntsha lymphatic no yog dab tsi? Vim li cas lawv thiaj tseem ceeb ua luaj?

Hais yooj yim xwb, cov hlab ntsha lymphatic capillaries yog ib lub network ntawm cov me me, mos mos uas khiav thoob plaws peb lub cev. Ib txhia ntawm lawv nyias li ib txoj plaub hau. Koj puas tau hnov ​​txog cov hlab ntsha, lossis cov hlab ntsha ntshav? Lawv zoo sib xws, tab sis muaj ob peb qhov sib txawv. Cov hlab ntsha lymphatic no kaw rau ntawm ib kawg, zoo li lub hnab me me. Lwm qhov tshwj xeeb yog tias cov kua dej tuaj yeem nkag mus rau hauv cov hlab ntsha no, tab sis lawv tsis tuaj yeem tawm los, zoo li lub qhov rooj uas tsuas yog qhib ib txoj kev xwb.

Lub cev me me no yog peb lub 'lymphatic system'. Lub lymphatic system no yog ib feem tseem ceeb ntawm peb lub 'immune system'. Lub cev tiv thaiv kab mob ua haujlwm zoo li peb lub cev tiv thaiv kab mob. Yog li, cov lymphatic capillaries zoo li cov tub rog tau kawm tshwj xeeb hauv pab tub rog tiv thaiv no. Lawv lub luag haujlwm tseem ceeb yog sau cov kua dej ntxiv, hu ua 'lymph', uas sib sau ua ke hauv ntau qhov ntawm peb lub cev thiab tswj nws kom zoo.

Cov lymphatic capillaries muab kev pabcuam dab tsi rau peb lub cev?

Cov haujlwm me me no ua yog loj heev, kom meej meej:

1. Tswj cov kua dej hauv lub cev kom sib npaug: Cov kua ntxiv uas sib sau ua ke nyob ib puag ncig peb cov hlwb, hu ua 'interstitial fluid', raug cov hlab ntsha lymphatic no nqus. Cov kua dej uas nqus tau no hu ua 'lymph'.

2. Kev tswj ntshav siab thiab ntim: Qhov no pab tswj peb cov ntshav siab thiab ntim los ntawm kev ntxiv cov lymph rov qab rau hauv peb lub cev ncig ntshav.

3. Tiv thaiv kev o: Cov hlab ntsha lymphatic no kuj pab tiv thaiv kev o (edema) kom tsis txhob sib sau ua ke hauv ntau qhov ntawm lub cev. Xav txog nws zoo li yog tias cov kwj dej hauv peb lub tsev tsis ua haujlwm zoo, dej yuav sib sau ua ke thiab puv lub vaj.

Puas yog nws tsis zoo kawg li? Lub kaw lus me me no ua haujlwm li cas?

Qhov no yog ib txoj kev nyuaj heev, tab sis zoo nkauj heev. Xav txog nws li no.

Cov phab ntsa ntawm cov hlab ntsha lymphatic yog qhov tshwj xeeb heev. Cov kua dej tuaj yeem nkag mus los ntawm lawv, tab sis nws tsis tuaj yeem tawm mus dua. Yog li, thaum cov kua dej ntxiv ntawm cov cell raug nqus mus rau hauv cov channel no, qhov siab hauv cov channel maj mam nce ntxiv. Vim yog qhov siab ntawd, cov lymph txav mus rau pem hauv ntej, uas yog, mus rau peb lub plawv.

Nov yog qhov tshwm sim ntawm txoj kev taug kev no:

• Ua ntej, cov lymph raug sau los ntawm cov hlab ntsha me me lymphatic no thiab tom qab ntawd dhau mus rau hauv cov hlab ntsha lymphatic loj dua me ntsis.
• Cov 'lymphatic vessels' no koom ua ke los ua cov 'caj pas' loj dua. Hauv cov ducts no muaj cov 'valves' me me, zoo li qhov rooj. Cov 'valves' no tsuas yog tso cai rau 'lymph' ntws mus rau ib qho kev taw qhia, tsis yog lwm txoj kev.
• Tom ntej no, cov lymph los ntawm cov 'cov ducts sau' no koom nrog 'sab xis lossis sab laug lymphatic duct'. Qhov no kuj hu ua 'thoracic duct'.
• Los ntawm cov lymphatic ducts no, lymph ntws mus rau hauv cov hlab ntsha loj hu ua subclavian veins hauv peb lub caj dab.
• Cov leeg ntshav no koom ua ke los ua ib txoj hlab ntshav loj heev hu ua superior vena cava.
• Thaum kawg, nws yog lub vena cava uas xa cov kua lymphatic huv rov qab mus rau peb cov ntshav.

Thaum lub sijhawm no, cov kua qaub ntshav hla dhau cov qog ntshav hauv peb lub cev. Ib yam li peb lub lim dej, cov qog ntshav no lim tawm thiab ntxuav cov qog ntshav ntawm cov khoom tsis xav tau, xws li cov kab mob. Tsuas yog tom qab ntawd cov kua qaub ntshav huv si thiaj li rov qab mus rau hauv cov ntshav. Puas yog nws tsis yog ib qho txheej txheem zoo kawg nkaus?

Cov lymphatic capillaries no nyob qhov twg hauv peb lub cev?

Tej zaum koj yuav xav tsis thoob thaum koj paub tias lawv pom yuav luag txhua qhov chaw hauv peb lub cev! Yog hais kom meej, feem ntau lawv pom nyob rau hauv qhov chaw nruab nrab ntawm peb cov hlwb (qhov "interstitial space").

Cov no yog "pob txha pob txha" thiab cov nqaij uas tsis muaj cov hlab ntsha. Piv txwv li, lawv tsis pom nyob rau hauv peb "cartilage" (qhov mos mos ntawm cov pob txha) thiab "epithelial" txheej saum daim tawv nqaij.

Cov feem ntawm cov hlab ntsha lymphatic yog dab tsi? Ib qho kev tshawb fawb me ntsis, tab sis tsim nyog paub!

Cov channel me me no muaj ntau qhov tseem ceeb:

• Cov hlwb Endothelial: Cov no yog cov uas ua rau cov phab ntsa ntawm cov hlab ntsha capillaries. Lawv raug teeb tsa ib qho rau saum ib qho, zoo li cov cib.
• `Lub plhaub hauv qab nthab`: Qhov no yog qhov uas txhawb nqa `cov hlwb endothelial` thiab ua rau lawv nyob hauv qhov chaw.
• `Mini-valves`: Peb tau tham txog cov no ua ntej lawm. Lawv tsuas yog tso cai rau cov kua dej nkag los xwb, tsis yog tawm los.
• Cov xov hlau txuas: Cov no zoo li cov xov me me. Lawv yog cov uas txuas cov hlwb endothelial rau cov nqaij nyob ib puag ncig. Lawv yog cov elastic.

Cov no zoo li cas? Puas yog lawv zoo li cov plaub hau tiag?

Yog, nws yeej mos heev. Lub lymphatic capillary zoo li ib lub raj. Nws txoj kab uas hla, uas yog, nws tuab, yog li 50 micrometers. Qhov ntawd yog li qhov loj ntawm ib txoj plaub hau. Ib kawg ntawm lub raj no kaw, zoo li daim nplooj ntoo qhib.

Cov phab ntsa ntawm cov no kuj nyias heev, tsuas yog ib lub cell tuab xwb. Vim tias cov cell no tau muab tso rau saum ib leeg, cov "kua dej" yooj yim nkag mus rau hauv cov hlab ntsha.
