Kodi phagocytosis ndi momwe zimachitikira

Zamkati

• Momwe zimachitikira
• Ndi chiyani

Phagocytosis ndimachitidwe achilengedwe mthupi momwe maselo amthupi amateteza tinthu tating'onoting'ono todutsa potulutsa ma pseudopods, omwe ndi nyumba zomwe zimakula ndikukula kwa nembanemba ya plasma, ndi cholinga chothana ndi kupewa matenda.

Kuphatikiza pokhala njira yochitidwa ndi maselo amthupi, phagocytosis itha kuchitidwanso ndi tizilombo tating'onoting'ono, makamaka protozoa, ndi cholinga chopeza michere yofunikira pakukula kwawo ndikukula.

Momwe zimachitikira

Phagocytosis yodziwika bwino komanso yomwe imachitika kawirikawiri imalimbana ndikulimbana ndi kupewa matenda ndipo, chifukwa cha izi, zimachitika pang'ono, monga:

1. Kuzungulira, momwe ma phagocyte amayandikira thupi lachilendo, lomwe ndi tizilombo tating'onoting'ono kapena kapangidwe kake ndi zinthu zopangidwa kapena kufotokozedwa ndi iwo;
2. Kuzindikira ndi kutsatira, momwe maselo amazindikira mawonekedwe omwe akuwonetsedwa pamwamba pa tizilombo, amawatsatira ndikuwatsegulira, ndikupangitsa gawo lotsatira;
3. Mpanda, yomwe imafanana ndi gawo lomwe ma phagocyte amatulutsa ma pseudopods kuti aphatikize wothandizirayo, zomwe zimayambitsa kupangidwa kwa phagosome kapena phagocytic vacuole;
4. Imfa ndi kusungunuka kwa tinthu tatsekedwa, yomwe imakhala ndi kuyambitsa kwa makina am'manja omwe angalimbikitse kufa kwa wodwalayo, zomwe zimachitika chifukwa cha mgwirizano wa phagosome ndi lysosomes, womwe ndi mawonekedwe omwe amapezeka m'maselo omwe amapangidwa ndi michere, zomwe zimapangitsa kumalo otsekemera am'mimba, komwe kumachitika chimbudzi chama cell.

Pambuyo pa kugaya kwamkati mwa maselo, zotsalira zina zimatsalira mkati mwa ma vacuoles, omwe amatha kuchotsedwa pambuyo pake ndi khungu. Zotsalazo zitha kugwidwa ndi protozoa, komanso kudzera mu phagocytosis, kuti izigwiritsidwa ntchito ngati michere.

Ndi chiyani

Kutengera ndi wothandizira yemwe amachita phagocytosis, phagocytosis itha kuchitidwa pazinthu ziwiri zosiyana:

• Limbani ndi matenda: pamenepa, phagocytosis imachitika ndi maselo a chitetezo cha mthupi, omwe amatchedwa phagocyte omwe amatenga tizilombo toyambitsa matenda ndi zinyalala zam'manja, kumenya kapena kupewa kupezeka kwa matenda. Maselo omwe nthawi zambiri amakhala ofanana ndi phagocytosis iyi ndi ma leukocyte, neutrophils ndi macrophages.
• Pezani zakudya: phagocytosis pachifukwa ichi imagwiritsidwa ntchito ndi protozoa, yomwe imakhala ndi zinyalala zama cell kuti zipeze michere yofunikira pakukula kwawo ndikukula.

Phagocytosis ndimachitidwe achilengedwe a thupi ndipo ndikofunikira kuti maselo a phagocytic azisankha wothandizila yemwe ayenera kukhala phagocyted, chifukwa apo ayi pakhoza kukhala phagocytosis yama cell ena ndi ziwalo zina m'thupi, zomwe zitha kukopa magwiridwe antchito oyenera a thupi.
