Phagocytosis - Nde mashandiro ari zvirwere

Most kazhinji kubva vakuru pokurerwa offsuit paTV, tinodzidza kuti zvirwere anogara muura. Zvose kunokosha kugeza, kubika, mudye zvakanaka, saturate muviri pamwe mabhakitiriya anobatsira uye nezvimwe zvakadaro.

Asi kutapata kunokosha kwete chete kuti. Muna 1908, Russian musayendisiti II Mechnikov akagamuchira Nobel Prize muna physiology nokumuudza (uye achiratidza) Kuwanikwa yose vakawanda uye kunyanya kukosha phagocytosis of zvirwere.

phagocytosis

Kudzivirira muviri wedu pashamwari nemavhairasi uye utachiona rinowanikwa muropa. The musimboti izvi: kune zvezvinangwa masero, vanoona muvengi uye anotarazve nayo, uye-kununura keji Label kuwana nokuparadza nomutorwa.

Phagocytosis - inofanira kuparadzwa, kureva, Absorção de Água anokuvadza zvipenyu masero uye zvisina upenyu inoramba kana zvimwe zvinenge pamwe mumasero anokosha - phagocytes. Kune 5 marudzi. Uye muitiro anobuda kwemaawa anenge 3 uye rinosanganisira 8 matanho.

zvokukura phagocytosis

Ngatitarisei muudzame chii phagocytosis. Izvi ndizvo zvakanaka chaizvo uye hurongwa:

• wokutanga phagocyte chiziviso chinhu zvazvinoita uye inofamba kwairi - danho iri rinonzi chemotaxis;

• vakabata chinhu, sero chakasimbiswa yaibatana, zvakabatanidzwa nayo, kureva inoomerera ..;

• anotanga Activate ganda rako - chokunze Kamudzira;

• Zvino anotanga chaiko phagocytosis pacharo: Fani iyi Kunoonekwa nokuumbwa pseudopodia vakakomba chinhu;

• zvishoma nezvishoma anopinda phagocyte sero utsinye mukati pasi wayo Kamudzira saka kuumbwa phagosome;

• Panguva iyi pane Fusion pamusoro lysosomes uye phagosomes;

• Zvino unogona kugaya zvose - kuparadza;

• kwokupedzisira Danho anogona chete kukandira kugayiwa zvokudya.

Zvose! Muitiro kuparadza muviri kunokuvadza kwapera, akaurayiwa nesimba zvomudumbu makemikari phagocyte kana somugumisiro kufema dzinokaroparuka. We akakunda!

Hazviiti parutivi, phagocytosis - unokosha chaizvo mashandiro muviri paaizvidzivirira hurongwa, iyo tinoberekwa vanhu nemhuka, chaizvoizvo - vertebrates uye invertebrates.

dramatis personae

In phagocytosis kunosanganisira kwete chete phagocytes. Pasinei chokwadi kuti masero aya vaiita nguva dzose vakagadzirira kurwa, vangadai pasina pasina cytokines. Pashure phagocyte, saka kutaura, ibofu. Haadi kusiyanisa shamwari uye vavengi, kana pane, havana kuona chinhu.

Cytokines - chokumbofanobata ezvinhu, imwe mhando kutungamirira nokuda phagocytes. Vakanga zvimwe chete akakwana "chiratidzo", zvakakwana ivo kunzwisisa ndiani uyo. Makwapa utachiona kana utachiona, ivo micheto yekapepa katsva aka pamusoro chiratidzo naro, kwakafanana nokunhuhwira, zvichava phagocyte.

Chinonyanya kukosha cytokines - mamorekuru anonzi chinja zvinhu. Avo rubatsiro phagocytes kwete chete kuziva muvengi, asi kutaura nemumwe, kudaidza rubatsiro, wakasvinura leukocytes.

Get nhomba, tinofanira kurovedza nayo cytokines, avadzidzise kuziva muvengi itsva.

marudzi phagocytes

Masero anogona phagocytosis, yakakamurwa nyanzvi uye vasiri nyanzvi phagocytes. Nyanzvi dziri:

• monocytes - ndivo masero machena eropa, vari zita remadunhurirwa rokuti "wipers", iro akagamuchira pamusoro rakasiyana kwaniso yekubata (kana ndizive kutaura kudaro, vane chido chakanaka kwazvo);

• macrophages - pavanokarira makuru uyo uchapedza masero akafa kana kukuvaradzwa uye kusimudzira paumbwe antibodies;

• neutrophils - nguva dzose wokutanga kusvika pa nzvimbo chirwere. Ndivo kupfuura vazhinji, tsime neutralize muvengi, asi ivo pachavo kufa panguva imwe chete (a mhando kamikaze). Zviya, pus - ndiye neutrophils akafa;

• dendrites - dzidzira mune utachiona uye kushanda uchikurukura zvakatipoteredza,

• rechikepe masero - the madzitateguru ane cytokines, uye kunyange rinonyura giremu negative utachiona.
