Taumahi me te hanganga o te waepuha

Waepuha Ko e kore anake te hanganga matua engari ano kōwae tākihi mahi. Ko konei e ko te wāhanga tino nui o te hanganga o te mimi. Na reira, ko te kōrero e titiro rite te hanganga o te waepuha, me he aha ngā mahi mahi reira, ka kia rawa ngā. I tua atu, ko te āhuatanga o nephron mahi e taea whakamārama i te mita o te pūnaha tākihi

Ko te hanganga o te waepuha: corpuscle tākihi

Ko reira ngā e i roto i te tākihi pakeke o te tangata hauora he i waenganui i te 1 me te 1.3 piriona nephron. Waepuha - he kōwae mahi, me te hanganga o te tākihi, e ngā o corpuscles tākihi me pera-ka karanga koropiko o Henle.

ngā takekore corpuscle tākihi o te glomerulus Malpighian me capsule o Bowman - Shymlanskaya. Hoki te tīmatanga ko reira ia tapao e te pōro ko mau he kohinga o tōiti iti. whiwhi toto i roto i iatuku konei prinosnuyu - e tātari wē. Balance toto ahu arterioles efferent.

Ko te capsule o Bowman - ngā o rua pepa Shymlanskaya - roto, o waho. A ki te mea ko te whārangi waho he papanga noa o epithelium squamous, te hanganga o te pepa roto tika atu te aro. Ko te roto rawa o te capsule ko podocytes whakamahau - he pūtau e te whakatutuki i te tūranga o te tātari atu. mahue ratou kūhuka, waikawa amino me ētahi atu matū, engari te ārai te kaupapa o ngā rāpoi ngota pūmua nui. Ko te kupu, i roto i te corpuscle tākihi i hanga mimi tuatahi, he rerekē i te i wē anake i te ngaro o ngā rāpoi ngota nui.

Waepuha: te hanganga o te tubule proximal me te koropiko o Henle

tubule Proximal Ko te hinonga i hono te corpuscle tākihi me te koropiko o Henle. Roto he Villi, e whakanui i te rohe katoa o te lumen ā, reira te whakanui ake i te mahi anō-mimititanga tubule.

tubule Proximal pai ki te wahi whakararo o te koropiko o Henle, āhuatanga nei i te diameter iti. Kei te tuku iho te koropiko ki te medulla wahi whakaiti huri noa tona tuaka ake e 180 nga nekehanga, me te kake - konei tīmata e haere ake wahi o te koropiko a Henle, e kua he nui nui me, i runga i, te diameter. Rising koropiko e takoto āhua i te taumata o te glomerulus.

Ko te hanganga o te waepuha: te tubules distal

Ko te wahi maranga o te koropiko o Henle i te uho haere ki te tubule ore distal pera-ka karanga. mai ia ki te whakapā ki te pōro, me i te whakapā atu ki te prinosnoy waho me arterioles. He te whakamana i te absorption fakataimí o ngā matūkai. haere tubule distal i roto i te wāhanga whakamutunga o te waepuha, i roto i te tahuri rere ki te ngongo kohikohi, te kūtere kawe i roto i te papatoiake tākihi.

whakarōpū o nephron

Ka rerekē i runga i te wāhi e wehea ki toru ngā momo matua o nephron:

• nephron cortical kėia āhua 85% o te katoa o nga wae hanganga katoa i roto i te tākihi. Ka rite ki te tikanga, kei te tū ratou i roto i te uho tākihi waho, i te mea, i roto i te meka, rite kitea e ratou ingoa. Ko paku rerekē te hanganga waepuha o tenei momo - ko te iti te koropiko o Henle;
• nephron juxtamedullary - taua hanganga e tika i waenganui i te roro, me te paparanga cortical, E koropiko roa o Henle e tomo hohonu ki te medulla, i ētahi wā pa koeko;
• nephron subcapsular - hanganga, e kua whakaritea tika i raro i te capsule.

Kia kï hoki, e te hanganga o te waepuha ko tino hāngai ki ona mahi.
