Oko waitinana ausia. Lymphatics tangata. Diseases o nga oko lymphatic

Ki te kahore he he pūnaha i te tinana, Na, he mea e hua ana. Ko te kounga o te ihirangi tei runga i te mahi o manga o te hanganga. Ka taea te pēnei katoa tenei āhuatanga ki te mahi o ngā pūnaha circulatory me lymphatic tangata. tirotiro hauora o enei hanganga Ko te take faufaa mo te mahi pūmau o te rauropi katoa. tātari I tua atu i roto i te taipitopito, he aha auraa toto, me te te tīpona oko. Kia tīmata a ki te muri.

Overview

oko lymphatic Human kanohi e hanganga rerekē ki te mahi i etahi mahi. Ko te kupu, ko te tuku:

• Tōiti.
• kahiwi Nui (rei me takere tika).
• oko Faa- me intraorgannye.

Ano, ko te hanganga o te uaua, me te he momo amyous. Ko te auau rere, me te pēhanga (tikanga hemodynamic) e tata ki te hunga e puta i roto i te rārangi venous. Ki te kōrero tatou e pā ana ki te mea te hanganga o nga oko lymphatic, me tuhia te reira anga waho pai whakawhanakehia. Nā ki te taupoki i roto e hanga e ngā paki.

capillary

rerekē tēnei oko lymphatic taiepa feunga permeable. Tōiti e taea o ngote rongoā slurry me colloidal. Ko te takere hanga he whatunga, e tohu te timatanga o te pūnaha lymphatic. Whakakotahitia ki te hanga i te hongere capillary nui. haere ia oko lymphatic i hanga ki te uaua subclavian mā te kaki, me te whaturei.

Whakatere nga takere o te ihirangi

Movement waitinana roto i te oko lymphatic kawea e tau mahani waha i roto i te moenga venous. E ai ki te awakeri rei puta ki tata katoa (anake te upoko) o te tinana. Rua tafe whakaurua i roto i te rua subclavian. I roto i te mau parau te tahi atu, kua hoki mai te wai katoa riro e te kikokiko ki te hoki toto. I roto i tenei whakaaro, ki te whānuitanga e puta rite te waitinana roto i te kaupapa oko lymphatic, kawea pana. A, no te maumaui puta matamua o te huru pathological. Kei te karangatia e te reira i limfostazom. Ko te huru te nuinga o ana tohu ngā huamo i roto i nga topito.

mahi pūnaha

Nga oko lymphatic me kōpuku runga ake katoa whakarite te tiaki o te tamau o te taiao ā-. I tua atu, mahi te pūnaha te mahi e whai ake nei:

• Mauranga i ngā matūkai intestinal i roto i te rua.

• Whai wāhi i roto i ngā tukanga immunological.
• Ka āta whakarite te reira i te hokinga o electrolytes, wai, te pūmua i roto i te toto i te wāhi intercellular.
• neutralizes te reira i te pūhui kino.

I roto i te akoranga o te oko lymphatic he kōpuku. whakatakotoria ratou wai. whakarato taikiri he waihanga wai, me te tiaki arai-tātari (whakaputa macrophages). Ko te ture o te matamua te maua e pūnaha kaungāongo'i io.

hanganga pāhekoheko

Kei roto i te pā tata ki te toto, timata matapo tōiti waitinana. Ko wāhanga o te hanganga microvasculature ratou. meinga tenei e te hononga mahi, me te kikokiko tata i waenganui i te toto me te oko lymphatic. Mai i gemokapillyarov tomo tūemi e tika ana i roto i te taonga taketake. Mai reira, i roto i te tahuri, i roto i te limfokapillyary tomo ngā matū. Tenei, i roto i ngā, i te hua o ngā tukanga pūkoro tinana, te parariraa o te pūhui i runga i te whakamārama o disorders pathological, ngā pūtau mate pukupuku. Taonga a tomo waitinana purea te bloodstream. Ko te kupu whakahōu reira te taiao ā-i roto i te rauropi me te intercellular (taketake) taonga.

rerekētanga hanganga

toto me te lymphatic oko Iti i diameters rerekē (te whakamutunga, ko te nui). pūtau Endothelial o te tuatahi ake atu i te tuarua, 3-4 wa. e kore Limfakapillyary whai i te membrane basal me pericytes, mutu matapo. Ēnei ngā hanganga hanga he whatunga me taka ki te hongere ekstraorgannye intraorgannye pāpaku.

postcapillaries

hongere efferent Intraorganic - reira amyous (kaiota) hanganga. Ia oko lymphatic he diameter o e pā ana ki 40 microns. pūtau Endothelial i roto i te awa takoto i runga i membrane ngawari. I raro i taua mea, he rapa me te collagen muka, e haere ana ki te waho anga. moenga Postcapillary te mahi pana mahi.

Ekstraorgannye moenga

rerekē ēnei oko ërä nui atu i nga mea o mua, me te e whakaaro ausia. no ratou ki nga hanganga o te momo uaua. Ki te te oko lymphatic ausia (Latin - vasa lymphatica superficialia) kei roto i te rohe o runga o te kātua, kaki, mata, reira ko feunga iti te myocyte. Ki te rere te ara haere te raro o te tinana me te waewae, atu i te āhuatanga uaua.

Ko te hanganga o te reo-ërä

Tenei hongere uaua-momo. He etahi peculiarities te hanganga o nga oko lymphatic o tenei rōpū. I roto i to ratou taiepa tautuhi makona pai katoa anga e toru: te waho, waenganui, me te roto. māngai te whakamutunga te endothelium takoto i runga i subendothelial membrane ngawari (kei reira-tini muka rapa me te collagen) me rapa muka plexuses.

Vaolo me anga

Ēnei āhuatanga kōrero ki ia atu tino tata. Vaolo e hanga e i roto i te anga i roto. Ka rite ki te pūtake tavini paraharaha kaiota. i reira he āhuatanga o te uaua maeneene i roto i tona ngakau. hipokina ana te pereti te endothelium. aerodynamics anga Toharite i hanga paihere o ngā pūtau uaua maeneene. E whakahaua ratou obliquely me circularly. kanohi hoki paparanga takotoranga o tūhonohono (wewete) kiko. i hanga te hanganga waho e te taua muka. Ko tōna huānga haere ki te kikokiko e karapoti ana.

awa Van Hoorne o

Tenei oko lymphatic kua he hanganga taiepa i te mea rite ki te hanganga o te iahoki vena cava raro. whakaratohia e te anga roto endothelium me subendothelium plexus ā muka rapa. Ko te tuatahi puta i taratahi membrane basal ngawari. Kei Subendothelium pūtau undifferentiated, rapa me te collagen muka, e kua hāngai i roto i ngā tohutohu rerekē, me te āhuatanga uaua maheni. anga i roto i roto i te tau mahani rei 9 i hanga te vaolo, whai wāhi ki te whakatairanga o uaua waitinana kaki.

Ko te hanganga waho i runga i te taumata diaphragmatic wha nga wa atu i roto, me te waenganui ngā. Ko te anga kanohi wewete kiko tūhonohono, me te uaua maeneene paihere, whakaritea ōna. oko waitinana ausia tomo te rua jugular. Tata te mangai o te taiepa mahani he kikokore atu i runga i te taumata diaphragmatic 2 nga wa.

Ētahi atu āhuatanga

I waenganui i nga mapuni e rua tikanga i roto i te oko waitinana tata, reira wahi motuhake. Kei te karangatia e te reira i lymphangions. Kei te māngai reira e te soté uaua, te piha taiepa pakohu me te wahi āpitihanga mau piha. E te aroaro te tau mahani rei tika, me te rite kahiwi nui. Enei āhuatanga o te myocytes pūnaha lymphatic (pūtau uaua) e kitea i roto i kiriuhi katoa (e toru).

taiepa Power tau mahani

I roto i te anga waho o te toto me te oko lymphatic whai takere oko. Enei manga matua iti mahuetanga paninga: waenganui, me te waho i roto i nga pera, me uaua i roto i te toru katoa. Mai i iatuku ūngutungutu taiepa capillary toto ki te uaua, me venules. E tū ana i muri ki te pera. Mai i te tōiti i roto i te anga i roto nekehanga toto venous ki te lumen venous. Power aerodynamics waitinana matua kua he singularity. takoto te reira i roto i te meka e kore e peka matua haere tahi i te venous whakawhānui wehe. E kore e nga oko iaia venules me arterioles kitea.

Mumura o nga oko lymphatic

whakaaro ana tēnei māuiuitanga te tuarua. Ko reira he pōauautanga o ngā tukanga inflammatory o te kiri (furuncles, karapanaka, patunga purulent tetahi), me te momo motuhake o mate (kohi, pakewakewa, etc). i roto i te tukanga e taea e whakapeka ma'i ranei. te huna hoki ano mumura motuhake, me te kore-motuhake o te oko lymphatic. huru no te mate e ahuatanga, ngoikore. I roto i te tūroro kirika. He āhuatanga āhuatanga o te māuiuitanga he mamae i roto i taikiri. Ka taea e te mate te pīmua e tetahi momo huakita pyogenic (Escherichia coli, Enterococcus, Staphylococcus). mate pāngia kahore uaua nui. E whakaritea mehua haumanu i runga ki te wā o te mate. Nga sulfonamides me paturopi e whakamahia rite te tikanga momo. I roto i te wā matatau, ringihia oko waitinana ausia te roto i te whakatuwheratanga o te whēwhē.

puku

a Hodgkin mate - lymphoma - pā pakeke te nuinga taitamariki (15-10 tau). he mea motu nga tohu i roto i te tīmatanga o te mate, a kahore te taikiri tetere o te manawanui ohorere. Ka rite ki te mate kauneke reira he metastasis. horahia te puku ki ētahi atu taikiri me okana, i roto i nei te nuinga o te mamae i te tuatahi kōateate. I muri i taua, timata ratou ki te whakaatu i nga tohu o te mate. I roto i ngā, whakawhanake te manawanui kirika, ngoikore, sweating, minamina kiri, heke taimaha. mate pāngia i leukocyte ako me te rauemi unuhanga.

lymphadenopathy

Hei te wehe i tēnei māuiuitanga i te tahi atu noa. I roto i ētahi wā, Heoi, kia ai taua mea uaua i nui haere ngā pūtau waha. wehea Lymphadenopathy ki urupare me te puku - kore-inflammatory, me te inflammatory. Tata whakarōpūtia ki ngā mate hopuhopu, me te kore-hopuhopu o nga oko lymphatic. tahi ratou haaparare i mate kiko tūhonohono, mate pāwera, kaikōiwi. hua urupare i roto i te tini waitinana kōpuku pūtau tohu he whakautu ārai tika ki te tukanga inflammatory whakaeke autoimmune, pāwera, hopuhopu ranei paitini. Ki te whakamārama o te puku ki te whakapiki ake i te āhuatanga hanganga ai kookuhutanga o ngā pūtau mārere e hinga i te tahi atu whēkau (mo e kanisā metastasis pukupuku ranei) i puta ake i roto i te pūnaha i runga i te papamuri o lymphomas mārere me lymphosarcoma ranei. Ka taea e māuiuitanga e whānui, me te iti. Te whakamutunga, Heoi, ka taea e te neke i roto i te tuatahi. I te tīmatanga tuku ki rite Hodgkin iti lymphadenopathy me ka, i muri i te ia, e tau te whakatakiruatanga o te reira. Ko te rōpū urupare ngā he tātaritanga te tika whānui o pathologies ngā.

tau mahani sarcoma

Ko tetahi o te natula mārere o te puku tenei. Ka taea e puta Lymphosarcoma rawa i tetahi tau. Ko te tikanga, ka tīmata te reira ki taikiri rahi i tetahi taha. āhuatanga tukanga puku e auau feunga nui o te ahunga whakamua, me metastasis ngā repara hohe. tino taea huru o te manawanui tupuheke i roto i te wa poto. Tūroro he kirika, tere heke taimaha tinana, sweats piki po. Tātaritanga He histological me rangahau cytological o te kōpuku tīpona pāngia.
