Naye lihlelo lymph lomuntu

Umzimba womuntu iqukethe izinhlelo ezimbili okuhambisana esibalulekile: kwegazi futhi lymph. Eyokuqala ugesi ukhonza njengephayona umzimba, kanti owesibili kusula ke kusukela izinto eziyingozi. Ososayensi bathi le somuntu sokujikeleza lymph (PM) kwavela ukuvela isimiso sokujikeleza kwegazi. Siqukethe capillary lymph, izitsha eziyishumi nemitshingo ezifana thymus, ubende, limfauzly, futhi yenza umsebenzi ukuqinisekisa outflow uketshezi ezicutshini zomzimba futhi amaseli isimiso sokujikeleza kwegazi. Nokho, ngokungafani kwegazi uhlelo izidakamizwa It has no imithambo futhi akusho ukuba khona umjikelezo omubi, ngakho impendulo yombuzo othi: evulekile noma avaliwe uhlelo lymph, kusobala.

Capillary kuthiwa kuhlobene kanjalo ukwakha inethiwekhi elivaliwe ihlanganisa cishe zonke kwezitho zomzimba. Zakhiwa endotolialnyh amaseli ngaphandle ulwelwesi. capillary lymph ukuncela kokubhubhisa amaseli, kuhlanganise lwesimila.

Capillary ukuze abe amamilimitha angu amabili ububanzi futhi tho ndawonye ukwakha kwemigudu ye-lymph, okuyinto aqukethe ama-valve, Amapayipi futhi iziqu. Ngokuvamile, izitsha zitholakala eduze ngemithambo; bangase uthanda ukuba baphathe lymph kusukela isikhumba (epifastsialnye) futhi baphathe i-lymph kusukela emisipheni nasemalungeni (izitsha subfascial). lymph limelela uketshezi esobala ezifanayo ukubunjwa ukuba plasma. lymph yakha Amapayipi eziyisithupha, okuyinto ngefomu ithuba ezimbili emgqonyeni main: isiqu thoracic kanye lymph kwesokudla.

Futhi, somuntu sokujikeleza lymph ithwala lymph kusuka ngaphakathi izitho zangaphakathi. Ngale ndlela kukhona ezingaphezu kweziyisishiyagalombili nokuba eziyishumi limfauzlov, ezibizwa ngokuthi "zesifunda". Lymph node Uyi isihlungi begazi nomzimba womuntu: kuzala amaseli ukuvikela umzimba ekulweni nezifo ezihlukahlukene nezilwanyana ezincanyana, kanjalo odala amasosha omzimba. Emzimbeni womuntu kukhona cishe sasiyikhulu namashumi amahlanu amaqembu lymph node, enkulu kunazo zonke zazo zitholakala emqaleni, e emakhwapheni, phezu nedolo endololwaneni, ngemuva entanyeni yakhe e imbilapho.

I limfauzlom enkulu Kusolwa ubende. Umzimba yokuphatha ukuqhutshwa sonke isimiso se-lymph, kuyinto thymus, etholakala esifubeni. Ngakho, amaseli weengazi awela kulesi umzimba ukuthi, aguqulwa aba amangqamuzana ukuthi angayiqeda kumiswa emibi abantu. Lapho isikhulile, la mangqamuzana jikisa izicubu fat.

Kufanele kuqashelwe ukuthi uhlelo lymph ayivaliwe: ama-lymph ezihambayo kwelinye direction - kusukela umzimba ukuze izicubu inhliziyo. Uma ukwephula kwenqubo lokuya kwaso, umuntu angase batfola ukuvuvukala. Lymph uyabanikeza amaseli nge mpilo nezakhi ezihlukene.

Kubalulekile ukwazi ukuthi emaphuzwini evamile lymph akuzona palpable. Uma kukhona isifo noma isimila, bangase lenyuke, ngakho-ke Kunconywa ezimweni ezinjalo, cela amacebiso kuchwepheshe.

Khuluma mayelana indlela somuntu sokujikeleza lymph kungaba ngemva izinqubo ezihlukahlukene zokuhlola ezifana palpation, ultrasound ukuhlolwa kanye imaging. Kuze kube manje, kukhona inani elikhulu izifo ezahlukene ohlelweni lymph, ngakho ekuhlonzweni kungasiza ngesikhathi lokwenza ukuxilongwa futhi baqala ukwelashwa okufanele.

Ngakho, uhlelo lymph lomuntu, kanye isimiso sokujikeleza kwegazi linendima ebalulekile ekusebenzeni umzimba womuntu. Njengoba isithiyo zokuzivikela ezifweni kanye nezifo eziningi, lwenza ukugeleza komoya-mpilo kwezitho zomzimba kanye nezakhi ezondla umzimba, kanye nokususwa ke imikhiqizo kwamazinyo, ngisho amangqamuzana omdlavuza.
