Chii chinonzi phagocytosis uye kuti zvinoitika sei

Zvemukati

• Sezvazvinoitika
• Chii ichochi

Phagocytosis chiitiko chemuzvarirwo mumuviri umo maseru ezvirwere zvemuviri anokomberedza tunhu tudiki kuburikidza nekubuda kwepseudopods, zvinova zvimiro zvinomuka sekuwedzera kwembambo yeplasma, nechinangwa chekurwisa nekudzivirira hutachiona.

Pamusoro pekuita maitiro anoitwa nemaseru edziviriro yezvirwere mumuviri, phagocytosis inogona zvakare kuitwa nemajemusi, kunyanya protozoa, nechinangwa chekuwana mishonga inodiwa mukusimudzira nekuwanda kwavo.

Sezvazvinoitika

Iyo yakajairika uye kazhinji phagocytosis inoitika inoitirwa kurwisa uye kudzivirira kukura kwehutachiona uye, nekuda kweizvozvo, zvinoitika mumatanho mashoma, anoti:

1. Kusvikira, umo ma phagocyte anosvika kune wekunze muviri, ayo ari ma microorganisms kana zvivakwa uye zvinhu zvinogadzirwa kana kuratidzwa nazvo;
2. Kuzivikanwa uye kutevedzera, umo masero anotarisa zvimiro zviri kuratidzwa pamusoro peiyo microorganism, zvinonamatira kwavari uye zvinogoneswa, zvichipa kumwe kuchikamu chinotevera;
3. Yakakomberedzwa, inoenderana nechikamu umo phagocytes inoburitsa pseudopods kuitira kuti ibatanidze inopinda mumiririri, inotungamira mukuumbwa kwepagosome kana phagocytic vacuole;
4. Kufa uye kugaya kwechikamu chakavharirwa, iyo inosanganisira kumisikidzwa kwema cellular michina inokwanisa kusimudzira kufa kwehutachiona hwehutachiona hutachiona, izvo zvinoitika nekuda kwekubatana kwepa phagosome nema lysosomes, chinova chimiro chiri mumasero ayo akaumbwa nema enzymes, zvichipa kusimuka kune digestive vacuole, uko mukati mecellular kugaya kunoitika.

Mushure mekudzivirira kwema intracellular, mamwe masara anogona kuramba ari mukati meiyo vacuoles, ayo anogona kubviswa gare gare nesero. Aya masara anogona kuzotorwa neprotozoa, zvakare kuburikidza ne phagocytosis, kuti ishandiswe seyakavaka muviri.

Chii ichochi

Zvichienderana nemumiririri anoita phagocytosis, phagocytosis inogona kuitirwa zvinangwa zviviri zvakasiyana:

• Rwisa hutachiona: mune iyi kesi, phagocytosis inoitwa nemasero eiyo immune system, ayo anonzi phagocytes uye ayo anoita anosanganisira pathogenic microorganisms uye maseru marara, kurwa kana kudzivirira kuitika kwehutachiona. Masero ayo anowanzoenderana neiyo phagocytosis ma leukocyte, neutrophils uye macrophages.
• Wana zvinovaka muviri: phagocytosis yechinangwa ichi inoitwa neprotozoa, iyo inosanganisira marara emagetsi ekuwana izvo zvinovaka muviri zvinodiwa mukukura kwavo uye kuwanda kwavo.

Phagocytosis inzira yechisikirwo yemuviri uye zvakakosha kuti maseru epa phagocytic anofanirwa kusarudza mumiriri anofanirwa kuve phagocyted, nekuti zvikasadaro panogona kunge paine phagocytosis yemamwe maseru uye zvivakwa mumuviri, izvo zvinogona kuve nehunhu pakushanda kwakakodzera yemuviri.
