Pinocytosis - He aha ka keia?

Ka mahuaola komo i loko o ka maloko halepaahao papa no ka lilo o ka hana amo, a ua mālamaʻia kuikawa nā'ūhū. Ma keia hihia, he mau keʻano o ka hanaʻana - pinocytosis a me ka phagocytosis.

General ano o ke kaʻina hana

Pinocytosis - ia mea he aoʻaoʻao o ka waha eʻai ai, i mea ano o ke kanu a me ka holoholona keena. Kona o Mānoa, ke moe ma ka hui 'ana me ka halepaahao māhuaola i ka mea hoʻoheheʻe palapala. Phagocytosis - he like kaʻina hana, akā, ma laila i ke kemu e paa (particles).

Ua ua ikeia ia pinocytosis mea nui i stimulus no ka ho okumu ana o lysosomes, a ua hoʻonoho phagocytosis ma luna o maʻiʻaʻai ana i keena ma nā mea hoʻomaʻi. Kēia mau keʻano o ka hanaʻana i ka hailonaʻana i loko, he pono ole, no laila, ka mea, ua pinepine collectively kapaia - cytosis a endocytosis, pinocytosis mea i oi prevalent. Inā i ka waiwai, ma ka mea ku ole, i loko mai o na keena, a laila, i kekahi olelo o ka exocytosis.

E helu mai, ua hiki ke olelo ia pinocytosis - he kaʻina hana o ke omo o ka halepaahao wai droplets.

kaʻina Hiʻona

Ano, e pono e mai la oia i ka halepaahao helu o ka mahana e kaukaʻi aʻaʻole hiki ke mālama 'ia ma ka 2 ° C, a ma lalo o ka hana ana o metabolic nā mea kūpale e like me paʻakai fluoride.

I pinocytosis hana outgrowths cytoplasm - pseudopodia, a merge i kekahi i kekahi, a Hoamakeikekula i ke kinowai droplets. Ma keia hihia na Oe i hanaia, a i kaawale mai o ka halepaahaoʻili lahilahi , a, e neʻe i ma ka cytoplasm, haliu ae la ia i loko o vacuoles kapaia pinosomy.

E noke i pinocytosis - mea i ka hopena o na keena olohelohe ia lakou i ka mea hoʻomaʻi mai paha. Ma keia hihia, ka mea i hanaʻia vesicles komo vibrios. Heʻaneʻi i ka mea, i kekahi manawa, olohelohe ia lakou i ka kahua o ka "paʻipaʻiʻole". kanaka ai 'I ka hoʻopio aku i nui nā lātoma i hele Oe ho okumu a me ka invagination - vacuole, akā, i keʻano papa hana o ka amo ana o ai' mea e noho pilikia. Nui ole ma ke omo o pharmacological Luna o kā lākou mau helehelena, fineness, a me ke alo o concomitant maʻi o digestive nā loko - gastritis a colitis, no kekahi laʻana, peptic ulcer.

kumuʻiʻo reabsorption i loko o kaʻaʻa puʻuwai tubules

Pinocytosis - heʻeleuʻano papa hana o ke kumuʻiʻo reabsorption i loko o kaʻaʻa puʻuwai proximal nephron. I loko nō o kona kumuʻiʻo attaches i ka palaki palena. Ma keia wahi invaginatedʻili lahilahi, pela i hana hue i loaʻa i ke kumuʻiʻo lātoma. I ka wā o ka kumuʻiʻo mea i loko o ka Oe, e hoʻomaka e decompose i loko o'amino nāʻakika, i a laila hāʻule ma ka basolateralʻili lahilahi i loko o ka extracellular loli. Mai ka ia amo pono ikehu, ka mea, ua kapaia kaila.

Ua mea waiwai 'ana i kumumanaʻo ana aia mea he manaʻo no i kā mākou amo o ka waiwai i mea' Imi reabsorbed. Kēia kaʻina ua pili i ka mea i kā mākou e haawe kekahi kaʻao ka 'oihana. Ua lŘlŘ ka wā o ka helu o nā wahi i pili, e loaʻa i loko o ka lumen o kaʻaʻa puʻuwai tubules, aku i na uea 'o nā'ūhū, a amo nā polokina komo i loko o ka hoololiia ana.

E like me he kumu, e hiki no hoi ka hopena i hoʻopōʻino monakō koko reabsorption e ia lŘlŘ ma ka proximal tubule o Kahualoa Kokohi. Inā ka maʻiʻo o ka waiwai aku iʻaʻa puʻuwai ooieoeiiaeuiuo uea, e hoʻomaka e hookaawale mai ka mimi (maʻamau monakō koko i 'akomi i).

Meaning o pinocytosis

Kēia kaʻina hana i wahi i loko o kaʻaʻa puʻuwai tubules a me ka intestinal epithelium. He mea kuleana no ka omo a me ka reabsorption o na mea he nui i huiʻia (me kumuʻiʻo a me ka nikiniki a) i ka mea pono no ka maʻamau functioning o ke kino.

¶ A, ka wā ae pinocytosis pūnao ma ka capillary pa. Penei, nui nā lātoma i hiki ole komo iloko ma ka ili o ka liilii, na moku koko, kaʻi aku ma pinocytosis. Ma keia hihia i ka capillaryʻili lahilahi ua invaginated keena, ma ia ho okumu i kekahi vacuole a poai puni i ka lātoma. Ma kaʻaoʻao e ku pono o ka hīnaʻi manu e ku pono kaʻina hoʻomaka e lawe wahi - emiocytosis.

Ua E hoi e hoike ia ia pinocytosis - mea he ke keʻena nui o kaʻeleu ion amo, a pili. I ka mea, o ke kumu nuiʻano papa hana o ka anal i loko o ka maloko 'ia o ke kiʻekiʻe hakakino waiwai o aeee. Eia hou, ka mea, o ke kumu nui ala o ka anal o ka holoholona a kanu nā mea hoʻomaʻi i loko o ka poʻe koa aeea.
