Sistimi ea lymphatic ke sete e rarahaneng ea litho tsa 'mele, lisele, likepe le methapo, tse ajoang' meleng oo mesebetsi ea ona e meholo e leng ho hlahisa le ho holisa lisele tsa 'mele tsa ho itšireletsa, ntle le ho ts'ila le ho sefa metsi a mangata' meleng., ho e lebisa maling.

Ts'ebetso ena ea mokelikeli, e bitsoang lymph, e etsahala ka li-capillaries, e leng lijana tse tšesaane tse hokahanang le lisele, 'me ha li fihla maemong a tebileng a mmele, li-capillaries li fetoha lijana tse kholo tsa lymphatic. Nakong ea phetiso ea lijana tsa lymphatic, lymph e feta ka litho, joalo ka lymph node, adenoids le spleen, e ikarabellang bakeng sa tlhahiso, polokelo le ho butsoa ha lisele tsa sesole sa 'mele, joalo ka li-lymphocyte, tse ikarabellang bakeng sa ts'ireletso le ntoa ea likokoana-hloko tsa kantle ho naha. .

Maemo a amanang le lymphatic system

Maemo a mang a ka baka liphetoho ts'ebetsong ea sistimi, a baka mafu, joalo ka:

1. Filariasis

Filariasis, e tsejoang hape e le elephantiasis, ke se seng sa mafu a mantlha a sistimi ea lymphatic mme e bakoa ke likokoana-hloko. Wuchereria bancrofti, e fetisetsoang ho batho ka ho longoa ke menoang ea mofuta ona Culex sp .. Ho lefu lena, likokoana-hloko li fihla likepeng tsa 'mele' me li baka tšitiso ea phallo ea lisele tse hlahisang ho ruruha ha setho se neng se sitisitsoe ho potoloha ha sona. Ithute haholoanyane ka matšoao a filariasis.

2. Kankere

Mefuta e meng ea mofets'e e ka baka ts'oaetso ea "lymphatic circulation" ka ho fihla lijaneng le litsing, joalo ka lymphoma, moo ho nang le ts'oaetso ea ho ata ha li-lymphocyte, e leng lisele tse ikarabellang bakeng sa ts'ireletso ea 'mele. ea tsamaiso ea lymphatic. Ka lebaka la keketseho e potlakileng ea li-lymphocyte, lia bokellana ebe li fella ka sebopeho sa hlahala, ntle le ho sekisetsa ho potoloha ha lymphatic.

Ntle le moo, sistimi ea lymphatic e ka fetoloa ka lebaka la metastasis kapa kholo ea lihlahala, joalo ka sefuba, mpa kapa hlooho le molala, ho lebisang liphetohong ts'ebetsong ea lymphatic system.

Bona se ka bakang mofetše oa "lymphatic".

3. Likotsi likotsing tseo e leng karolo ea lymphatic system

Liso tse mokong oa masapo, spleen, lymph node kapa spleen, e leng litho tse etsang sistimi ea lymphatic, ka lebaka la ho otloa kapa ka lebaka la kalafo le tsona li ka fetola phetiso ea lymphatic. Boemo bona bo ka etsahala haholo ho basali ba kileng ba fuoa kalafo ea mofetše oa matsoele ka radiography, ba baka liphetoho mohalong oa ho ntša metsi oa lymph, ntle le hore o tlositsoe li-lymph node sebakeng sa armpit.

4. Malformation a tsamaiso ea lymphatic

Ho senyeha ha sistimi ea lymphatic ho boetse ho baka liphetoho phetisong ea lymph mme ho atile khafetsa ka lebaka la liphetoho lijaneng kapa lymph node.

Ka ho senya phetiso e nepahetseng ea lisele tsa mali maling, maemo ana a hlahisa lymphedema, e leng ho ruruha 'meleng ho hlahisoang ke ho bokellana ha lisele le mokelikeli ka har'a lisele tsa' mele.

Anatomy ea tsamaiso ea lymphatic

Sistimi ena ea bohlokoa e entsoe ka marang-rang a rarahaneng a lisele, likepe, lisele le litho, tse etsang mesebetsi e fapaneng. Likarolo tse kholo li kenyelletsa:

1. Lymph

Ke mokelikeli o tsamaeang ka phallo ea lymphatic, hangata e tsoang ho dutla ha mokelikeli o tsoang molapong oa mali o kenang liseleng tse potileng lisele.

Mosebetsi: mokelikeli o kantle ho lijana o khona ho hlatsoa lisele, o fana ka limatlafatsi tse hlokahalang, empa ha o ts'oaroa ke lymphatic current, o fetoha lymph, e isoang pelong, hore o khutlele maling.

2. Li-capillaries le likepe tsa lymphatic

Li-capillaries ke lijana tse nyane tse tšesaane tsa lymphatic, tse kopanang le lisele tsa 'mele ebe li nka maro,' me ha li ntse li isa lisele pelong, lia hola ebe li theha lijana le methapo e meholo ea lymphatic.

Mosebetsi: ho nka le ho monya mokelikeli le liprotheine tse potileng lisele, ho thibela ho bokellana ha maro le ho ruruha 'meleng.

3. Litsela tsa lymphatic

Ke liteishene tse kholo tsa lymphatic, tse tsejoang ka hore ke seretse sa thoracic le se nepahetseng sa lymphatic, moo phallo ea lymphatic e phallang pele e fihla maling.

Mosebetsi: mosele oa thoracic o bokella le ho tsamaisa boholo ba lisele tsa mmele ho ea maling, athe mosamo oa lymphatic o ikarabella ho tšolla lymph ho tloha leotong lohle le kaholimo le lehlakoreng le letona la hlooho, molala le sefuba maling.

4. Litho tsa 'mele

Ke litho tse hasaneng tseleng ea likepe tsa lymphatic, tse nang le boholo bo fapaneng, sebopeho le ts'ebetso, mme li ka khothatsoa neng kapa neng ha ho na le ts'oaetso kapa ho ruruha. Tse ka sehloohong ke tsena:

• Lesapo la masapo: ke sebopeho se kahara masapo a maholo, se nang le tšebetso ea ho etsa lisele tse fapaneng tse etsang phallo ea 'mele, ho kenyeletsoa lymphocyte, e leng lisele tsa ts'ireletso tsa lymphatic system;
• thymus: ke tšoelesa e karolong e kaholimo ea sefuba, e nang le ts'ebetso ea ho nts'etsapele le ho holisa li-lymphocyte tsa T tse tsoang mokong oa masapo, ebe li ea liseleng tse ling tsa lymphoid, moo li kenang ts'ebetsong bakeng sa boits'ireletso ba mmele;
• Lymph nodes: ke litho tse nyane tse chitja, tse hasaneng haufi le likepe tsa lymphatic, tse ikarabellang bakeng sa ho sefa lymph, ho tlosa likokoana-hloko, joalo ka libaktheria le livaerase, le likaroloana tse ling tsa mali, ntle le ho ba le boikarabello ba ho nona le ho boloka li-lymph node, tse loketse ho nka khato khahlanong le tšoaetso.
• Bokoa: ke setho se seholo sa lymphatic, se karolong e kaholimo ho le letšehali la mpa, se ikarabellang ho boloka le ho nonafatsa ha li-lymphocyte, ntle le ho sefa mali, ho felisa likokoana-hloko le lisele tse tsofetseng.

Ntle le moo, ho na le lithane, tse tsejoang ka hore ke lithane le adenoids, e leng lihlopha tsa li-lymph node, tse molomong, sebaka se tlase sa leleme le pharynx, ntle le maballo a Peyer, a ka maleng, a ikarabellang bakeng sa ho hlahisa lisele tsamaisong ea boits'ireletso le ho thusa ho itšireletsa khahlanong le likokoana-hloko.

Letsoai la lymphatic ke lefe

Letsoai la lymphatic ke ts'ebetso e nang le ho silila ka metsamao e boreleli, e ikemiselitseng ho hlasimolla le ho tsamaisa ho tsamaisoa ha lymph ka methapo ea eona, ebe e fihla maling kapele.

Kaha sistimi ea lymphatic ha e na pompo, joalo ka ha e etsoa ke pelo maling, ho silila hona ho ka thusa ho khutlisetsa lymph, haholo ho batho ba nang le bothata ba likepe tsena mme ba tloaetseng ho bokella maro liseleng. .

Ha o etsoa ka mokhoa o nepahetseng, ts'ebetso ena e ka ba molemo ho felisa ho ruruha ho hong sefahlehong kapa 'meleng. Hlahloba hore na melemo ke efe le hore na drainage ea li-lymphatic e tsamaisoa joang.
