He aha ka phagositosis a pehea e hana ai

Anter

• Ke hiki mai
• No ke aha ia

ʻO Phagocytosis kahi hana kūlohelohe i ke kino kahi e hoʻopili ai nā hunaola o ka ʻōnaehana pale i nā huna nui ma o ka hoʻokuʻu ʻia ʻana o nā pseudopods, nā hale e kū aʻe ma ke ʻano he hoʻonui o kona membrane plasma, me ka pahuhopu o ke kaua a me ka pale ʻana i nā maʻi.

Ma waho aʻe o kahi hana i hana ʻia e nā hunaola o ka ʻōnaehana pale, hiki ke hana ʻia ka phagositosis e nā microorganism, ʻo ia hoʻi ʻo protozoa, me ke kumu o ka loaʻa ʻana o nā meaola e pono ai no kā lākou ulu ʻana a hoʻonui.

Ke hiki mai

ʻO ka phagocytosis ʻoi loa a pinepine e kū i ke kaua a pale ʻana i ka ulu ʻana o nā maʻi a, no ia mea, hana ʻia ia i kekahi mau ʻanuʻu, ʻo ia hoʻi:

1. Kokoke, kahi e hoʻokokoke aku ai nā phagosit i ke kino haole, ʻo ia nā microorganism a i ʻole nā ​​hanana a me nā mea i hana ʻia e haʻi ʻia e lākou;
2. ʻIke a me ka mālama ʻana, kahi e ʻike ai nā hunaola i nā kūkulu e hōʻike ʻia nei ma ka ʻili o ka microorganism, pili iā lākou a hoʻoheheʻe ʻia, e ala ana i ka wā aʻe;
3. Paʻi, i kūlike i ka ʻāpana e hoʻopuka ai nā phagocytes i nā pseudopods i mea e hoʻopuni ai i ka mea komo hewa, e alakaʻi ana i ka hoʻokumu ʻia ʻana o kahi phagosome a i ʻole kahi vakuous phagosittic;
4. ʻO ka make a me ka digestion o ka huna i hoʻopuni ʻia, ʻo ia hoʻi ka hoʻoulu ʻana o nā ʻano hana kelepona hiki ke hāpai i ka make ʻana o ka mea maʻi lele, i hana ʻia ma muli o ka hui ʻana o ka phagosome me nā lysosome, kahi hanana i loaʻa i loko o nā hunaola i hana ʻia e nā enzyme, e ala ana i ka holoi digestive, kahi e loaʻa ai ka digestion intracellular.

Ma hope o ka digestion intracellular, e koe kekahi mau koena i loko o nā vakuola, a hiki ke hoʻopau ʻia e ka pūnaewele. Hiki ke hopu ʻia kēia koena e ka protozoa, a ma o ka phagositosis, e hoʻohana ʻia me nā mea momona.

No ke aha ia

Kaukaʻi ʻia i ka konohiki e hana ana i ka phagocytosis, hiki ke hana ʻia ka phagositosis no ʻelua mau kumu like ʻole:

• E hakakā i nā maʻi: i kēia hihia, lawe ʻia ka phagositosis e nā hunaola e pili ana i ka ʻōnaehana paleʻea, i kapa ʻia nā phagocytes a me nā hana e pili ana i nā microorganism pathogenic a me nā ʻōpala pūnaewele, ke kaua a pale ʻana paha i nā hanana o nā maʻi. ʻO nā pūnaewele e pili pinepine ana i kēia phagocytosis he leukosit, neutrophil a me macrophages.
• Loaʻa i nā mea momona: Hana ʻia ʻo phagocytosis no kēia kumu e ka protozoa, kahi e hoʻopili ai i nā ʻōpala pūnaewele e kiʻi i nā meaola kūpono no ko lākou ulu a hoʻonui ʻana.

ʻO Phagocytosis kahi hana kūlohelohe o ka meaola a he mea nui e koho pono nā hunaola phagosittic i ka agena e pono ai phagocyted, no ka mea inā ʻaʻole hiki i ka phagositosis o nā hunaola ʻē aʻe a me nā hale i ke kino, i hiki ke hoʻohuli i ka hana kūpono. o ka meaola.
