Physiology thiab tib neeg lub cev. Lub lymphatic system

Lub lymphatic system - nws yog ib feem ntawm cov hlab plawv system, uas complements nws. Nws ua ib qho tseem ceeb functions nyob rau hauv tib neeg lub cev thiab nws cov kev kho mob no tseem ceeb heev rau nws lub neej. Lymph txawv los ntawm cov ntshav uas tsis ntws nyob rau hauv ib tug vicious voj voog. Nws txav yog qeeb heev, vim hais tias nws xav tau kev pab yuav tsum tau tsa.

Nthuav fact! Nyob rau hauv ancient sij hawm, qhov lymphatic system pom raws li lub ntsiab determinant ntawm tus tib neeg li cas. Luv, nyob rau hauv lem, txhais ib pab pawg neeg ntawm cov kab mob uas txom neeg.

Yuav ua li cas yog lub lymphatic system?

Raws li cov lub cev ntawm lub tib neeg lymphatic system permeates tag nrho lub cev. Nws muaj xws li:

• hlab ntsha;
• hlab ntsha;
• ntshav;
• lymphatics thiab yeej;
• lymphatic kabmob.

Raws li nws, cov kua ntws connective cov ntaub so ntswg - lub qog, qhov tseem ceeb ntawm uas - nws yog dej, ntsev, cov nqaijrog, Sibhawm. Nws muaj pes tsawg leeg yog zoo rau cov ntshav ntshav, lub mov lub cev. Lymph tsis muaj kob. Nyob rau hauv tib neeg, nws muaj los ntawm 1 mus rau 2 liv.

Yuav ua li cas puas cov qog tsim?

Lymph tsim tshwm sim nyob rau hauv cov nram no txoj kev. Cov ntshav hlab ntsha tshwm sim nyob rau hauv cov ntshav ntshav filtering. Cov kua nyob hauv lub txiaj ntsim ntawm no filtering yog thauj rau hauv lub extracellular qhov chaw. Yog li tsim cov ntaub so ntswg kua, ib feem ntawm uas yog xa rov qab mus rau cov ntshav, thiab lwm qhov kis mus rau hauv lub qog cov hlab ntsha. Nws zog nyob rau hauv lub contraction ntawm cov nqaij, lub cev txoj hauj lwm thiab ua tsis taus pa.

Ntawm no xws nws yog ib qhov nyuaj - tib neeg lub cev. Lub lymphatic system thiab storoenie cov xwm xav mus rau lub me tshaj kom meej. Xav txog qhov no kev tivthaiv ntawm tib neeg lub cev nyob rau hauv kom meej.

Tus qauv ntawm lub lymphatic system

Lymphatic hlab ntsha - ib tug me me raj ntawm txawv txoj kab uas hla, devoid ntawm ib tug nyias nyias, uas pib blindly. Lawv tsim lub compound vim interlacing nrog txhua lwm yam, dua nyob rau hauv postcapillaries uas yog loj formations muaj li qub. Cov qub thawb lub qog nyob rau hauv ib tug coj, kev tiv thaiv nws txav rov qab.

Ceeb toom! Lo lus "cov qog" yog tsis muaj tseeb, vim hais tias cov qog yog ib yam khoom ntawm lub endothelium thiab mezhendotelialnyh khaubncaws sab nraud povtseg, txhua lub sij hawm rov qab rau hauv lub cev. Cov kws kho mob hu rau tus txheej txheem no ntawm cov qog.

Raws li cov ceg biology hu ua "tib neeg lub cev", lub lymphatic system kuj muaj cov hlab ntsha uas tsim los ntawm postcapillaries. Qhov loj tshaj plaws ntawm lawv ua raws li txoj kev ntawm cov leeg thiab cov hlab ntsha, thiab raug xa mus rau raws li lolus. Lawv sau cov qog ntawm cov loj tshaj plaws qhov chaw - lub Upper thiab qis nqua, kabmob. Subdivided rau hauv internal (nyob ze ntawm lub hlab ntsha) thiab sab nraud (nyob rau hauv lub subcutaneous cov ntaub so ntswg). Tsis tas li ntawd cov hlab ntsha raug muab faib ua afferent thiab efferent (nyob ntawm seb cov qog txaus nyob rau hauv kev sib raug zoo mus rau lub qog).

Los ntawm cov neeg sau yog tsim lymphatic trunks, uas yog hloov dua siab tshiab rau hauv lub ducts.

cov qog ntshav hauv

Lub lymphatic system ntawm tus neeg (lub cev rau ib tug ntev lub sij hawm tsis tau muab qhov no yog ib feem ntawm peb vim xim rau lub cev) kuj muaj nws cov "tshuaj". Lymph ntshav - ib tug me me tsim ntawm yeej los yog lub voj qe muaj ib lub cheeb ntawm txog 2 cm Lawv muaj ib tug pinkish-grey zas .. Lawv nyob raws lub lymphatic hlab ntsha. Cov tub ntxhais hluas predominate cov qog ntshav hauv yog dawb rau hauv cov duab, thiab nyob rau hauv cov neeg laus, lawv yog ncav us txog nyob rau hauv ntev. Lawv lub ntsiab muaj nuj nqi - ib tug cleansing ntawm lub qog los ntawm cov tshuaj lom tshuaj tau muaj. Lymph ntshav ua si lub luag hauj lwm ntawm ib lim, uas cuab toxins thiab "tawm" tau twb cleared qog.

Lymphatic kabmob - ib tug po, tonsils thiab thymus (uas muaj los ntawm kev ua hluas). Lawv lub ntsiab muaj nuj nqi - inhibit qhov kev taw qhia thiab kev loj hlob ntawm kab mob nyob rau hauv lub cev.

Yuav ua li cas zog nyob rau hauv lub cev yog tus lymphatic system?

Ib qho ntawm feem complex thiab intricate science yog tib neeg lub cev. Lub lymphatic system, uas nws tso cai no tseem ceeb heev rau lub cev, ua ib txoj hauj lwm.

Ua ntej ntawm tag nrho cov, nws yog lub luag hauj lwm rau lub cev teb ntawm lub cev, tiv thaiv nws los ntawm kev sib cuag nrog cov kab mob thiab cov kab mob. Uas yog vim li cas, nyob rau hauv teb mus rau lub allergic ntawm lub pathogen rau hauv lub cev (kab mob ntawm tus kab mob no) nce lymph node. Nws yog lawv nce nyob rau hauv cov me nyuam qhia muaj cov, hais tias, tuberculosis, tab sis, nyob rau hauv tas li ntawd, cov qog ntshav yog nce thiab ib tug xov tooj ntawm lwm yam kab mob. Cov kev tiv thaiv nuj nqi muaj ob kauj ruam:

• kab mob kev puas tsuaj ntawm macrophages;
• zus tau tej cov lymphocytes.

Filtering cov ntshav. Tus po txav ntshav liab thiab tua tag nrho cov kab mob thiab cov kab mob uas muaj nyob rau hauv cov ntshav. Hluas ntshav liab tsim hlwb pob txha. Filtering qog. Yog hais tias cov ntshav yog pathogens, ces tus qog yog lim lawv. Nws yog vim li no, nyob rau hauv tus neeg mob uas xav tias Oncology cov kws kho mob thawj saib rau lub xub ntiag ntawm cov qog ntawm metastases. Lub lymphatic system ntawm tus neeg (lub cev sib tham luv luv) nyob rau hauv cov ntaub ntawv no qhia tau hais tias yuav ua li cas tus kab mob tau kis thoob plaws lub cev.

Lub outflow ntawm cov kua los ntawm cov ntaub so ntswg mus rau hauv cov ntshav. Ntshav, nyob rau hauv cov ntshav seeps los ntawm cov hlab ntsha nyob rau hauv lwm yam ntaub so ntswg. Nws kis tau los ntawm cov lymphatic hlab ntsha, ntxuav thiab dua rov qab mus rau cov ntshav. Xws li ib tug kev yog mus li.

Kab mob ntawm cov lymphatic system

Raws li cov tib neeg lub cev, cov lymphatic system yog tsis tshua muaj ib qho tseem ceeb rau cov kev kho mob ntawm lub cev, thiab nws yuav tsis muaj peev xwm ua rau mob loj teeb meem.

Ntawm cov pab pawg ntawm cov kab mob ntawm lub lymphatic system yog raug rho tawm:

• malformations;
• kev poob plig;
• o;
• qog.

Ib qho ntawm thawj cov tsos mob ntawm cov kab mob - qog o thiab lub cim txo ntawm kev tiv thaiv. Nce tawm hws, nkees, mob taub hau cov neeg mob muaj kev txhawj xeeb, lub kub yuav tau tsa ceg. Tshwm sim qog edema. Kab mob ntawm cov qog tshwj xeeb txaus ntshai vim hais tias nyob rau hauv lub cev pib noog co toxins. Uas yog ib tug ua txhaum ntawm nws kev ua muaj feem xyuam rau tag nrho cov nruab nrog cev thiab lub cev.

Txoj kev rau cov kev kho mob ntawm pathologies ntawm lub lymphatic system yog ncaj qha nyob rau hauv lub hom ntawm tus kab mob. Kev kho mob tej zaum yuav txawv - los ntawm conservative rau Radial los yog ua hauj lwm txoj kev.

Peb cia siab tias cov neeg uas txaus siab nyob rau hauv tib neeg lub cev, cov lymphatic system (duab, uas qhia yuav ua li cas nyuaj no yog ib feem ntawm peb lub cev, uas hais nyob rau hauv tsab xov xwm) thiab nws cov kev khiav dej num, kawm tau ntau yam ntawm cov tshiab thiab nthuav yam uas hais txog cov ib puag ncig ntawm ib tug kab mob. Yuav ua li cas kom nws noj qab nyob zoo?

Cov kev kho mob ntawm cov lymphatic system

Ua ntej ntawm tag nrho cov, cov kws kho mob pom zoo kom mus saib xyuas lawv kev noj qab nyob thiab tiv thaiv kom txhob irregularities nyob rau hauv lub mob huam, txij li thaum nws entails lub kuab paug ntawm cov tag nrho lub cev thiab cuam tshuam nrog cov lymphatic system. Nws tsis tiv nrog cov khiav ntawm toxins. Saib koj noj cov zaub mov.

Ob zaug ib xyoos, ua ib tug zaws. Qhov no txoj kev zoo accelerates tus lymph, tab sis tshwj xeeb tshaj yog rezultativen lymphatic kua zaws, uas ncaj qha muaj feem xyuam rau cov qog. Yog hais tias koj tsis tau mus ntsib ib tug kws kho mob zaws, nyob rau hauv tus da dej, txhuam lub cev phuam ntxuav muag tam sim no cov qog.

Tswj koj qhov ceeb thawj. Lymph yog rhiab heev rau nyhav dhau heev lawm. Muaj ib tug active txoj kev ua neej thiab yuav noj qab nyob zoo!
