Lisele tsa mmele nodes, likepe tse le makala lymphoid - dipehelo tsa tsamaiso lymphatic

Tsamaiso lymphatic ke nako e telele a Lula a li sa utloisisoe ho, seabo lona ha e so tsebahalang. Ho sa le joalo, ho e hlokahala haholo 'meleng. Tsamaiso lymphatic hloekisa 'mele oa dintho tse ke keng tsa ananelang ka ho toba ka dinama tse nyenyane tse ea mali - ka ditharollo colloidal ea lihaha-'mele, mafura emulsion, suspensions ea libaktheria le maloanlahla a lisele. All ena e kena lisele tsa mmele wa ebe le eona tšollela ka maling. Lisele tsa mmele na le palo e khōlō ea lymphocytes - lisele tsa mali a mofuta o itseng. lisele tse tsena kokobetsa ho libaktheria le lisele tse kankere.

Tsamaiso lymphatic na le methapo ea lisele tsa mmele, lisele tsa mmele nodes le makala lymphoid. Ke litho tsa lymphoid kenyeletsa spleen, tonsils, ho thymus tšoelesa. Ho fapana le methapong koetsoeng, lisele tsa mmele simoloha ho toba ka makala le lisele. Ka methapong lisele tsa mmele - lymphatics. Joaloka methapong, likepe lisele tsa mmele na valve tsamaisa phallo ea lisele tsa mmele ka tataiso e 'ngoe. All lisele tsa mmele lijana lymphatic ile bokella le 'mele' ohle le phalla ka thoracic lisele tsa mmele difapho le letona.

Ikutloeleng lijana lymphatic ke lisele tsa mmele nodes. Ke 'nete-filter loantsang likokoana' meleng. lisele tsa mali, ka mafolofolo loantša tšoaetso - palo e khōlō ea lymphocytes ba concentrated ka nodes lisele tsa mmele. E lokela ho ba haufi le lisele tsa mmele noute hlaha ka efe kapa efe dikokwanyana, kapele-pele ba hlasela 'me kokobetsa ho lymphocytes. Ha palo e khōlō ea likokoana-hloko, e leng lisele tsa mmele nodes eketseha ka seemo. nodes tsena ka habonolo palpated ka tlas'a letlalo. Sena se etsahala, ho etsa mohlala, ka a batang kapa ho ruruha ea periosteum leino. Lisele tsa mmele nodes ka 'mele oa motho e ngata le ho bona hore palo ea bona ea bonyane ka etsahala. Lisele tsa mmele nodes ba lokisetsa ka lihlopha tse entsoeng ka nodes maloa haufi lijana venous mali.

Kakaretso ea palo ka lihlopha tse 150 lebatowa ya nodes. Kholo ka ho fetisisa ba bona ba - the lisele tsa mmele nodes ka groin e, ka hotel kaya, litsoeng, popliteal, submandibular, cervical, occipital, iliac, celiac, nodes mediastinal le ba bang. Nodes teng ka hare ho thoracic kapa mpeng cavity bitsoa visceral le surfactant di - parietal.

Ka nodes tloaelehile lisele tsa mmele di palpable. Atolosoa lisele tsa mmele nodes ba mafu a sa tšoaneng le ho mo sebeletsa e le ea bohlokoa ho hlahloba lefu letšoao. Ka mafu a hlabang, e atolositsoeng lisele tsa mmele nodes palpable ka tse nyenyane e etsoang ka mechine, bohloko, lekaneng ho tiiso ho lekanya hoo e ka bang disentimitara le bophara ba. Palpate atolositsoeng lisele tsa mmele nodes ka ke visceral. Keketseho le hlaha haufi le libaka tsa ho ruruha tsepame. Ka mor'a hore tsela ea dikarolo kalafo ba fokotswa ka boholo, ba sa bonahaleng le bohloko.

Lisele tsa mmele nodes ne e atolositsoeng le se bolaeang dithulaganyo. Tabeng ena, ho nodes ba le letšo-letšo, immobile, bohloko, soldered ho lisele tse e potolohileng. letšoao lena develops ka kankere, kankere ea mali, lefu la Hodgkin.

Ka makala a lymphoid le hlaha lymphocyte popego ya mmele. Ka spleen ho, ho phaella timetsoa khale lisele tse khubelu tsa mali, e leng seo hangata se bitsoang mabitleng bona. Hobane karolo e khōlō ea lymphoid dinama tse nyenyane tse a qapa tonsils, sehlomathiso kapa sehlomathiso. dinama tse nyenyane tse Lymphoid e teng marakong a mala, intestine nyenyane le mala. Ka lilemo, ka tjhelete e ya dinama tse nyenyane tse 'meleng butle-butle decreases, a tsamaea le ea fokotseha ka reactivity ya boitshireletso ba mmele, ho eketseha le matsoai a hlokoang.
