Ali chiwindi anthu? ndi ntchito zake chiyani?

Osati munthu aliyense walandira digiri dokotala, koma zosachepera tidziwe zina za thupi lake sakuwupweteka. Mwachitsanzo, zingakhale bwino kudziwa za malo ndi ntchito ziwalo zathu mkati. Koma monga mukudziwa, ife sindikuganiza za komwe mu chiwindi anthu, mpaka zimapweteka.

Makamaka amphamvu zisakuyenda kwa anthu akuvutika thupi imeneyi. Choncho pambuyo pa zonse, kumene kuli mu chiwindi anthu? limba ili pansipa nthiti kumanja wa pamimba m'bwalo chapamwamba. Pa mlingo wa nipple abwino chapamwamba womangidwa chiwindi.

Kuyambira mfundo anatomical amazionera, chiwindi zikhoza kugawidwa m'magulu awiri - lamanzere ndi lamanja. Tikumbukenso kuti kumanja ndi kasanu ndi kamodzi lalikulu kuposa kumanzere. Komanso ali ndi zigawo ziwiri - ndi chiwerengero lalikulu la padziko m'munsi ndi tailed pa kumbuyo kwa gawo lapansi. Pakati pa chabwino ndi kumanzere chiwindi ndi peritoneum - khola, limene mankhwala amatchedwanso zenga mitsempha. ili poyambira imene ili mtolo venous Pa kumbuyo kwa chiwindi. Komanso chochokera poyambira pansi, limene lili mkati mitsempha chonse. Chotero dongosolo zovuta chiwindi ndi N'zosadabwitsa: lililonse chinthu chofunika njira ya ntchito za thupi.

Pakuti kugwira ntchito za masiku onse chiwindi ayenera nthawi zonse aziwapatsa magazi. Izi zimachitika kudzera m'mitsempha zipata, omwe amanyamula magazi venous ku ndulu ndipo matumbo, ndi mtsempha wamagazi kwa chiwindi, amene osabwereranso kumeneko mpaka zitanyowetsa thupi ndi oxygen. Choncho, ife anayankha funso, amene ndi chiwindi anthu.

Chiwindi - mmodzi wa ziwalo zofunika kwambiri, iye ndi udindo pogwira ntchito zambiri, popanda munthu sipangakhalenso. Waukulu ntchito ya chiwindi mu thupi:

- neutralization wa poizoni kuti chakudya pa moyo wa mabakiteriya kugwa mu dongosolo m'mimba pamodzi ndi chakudya;

- nawo kagayidwe mapulotini, chakudya mafuta;

- Kupanga ya ndulu, chimene chili chofunika kwa pogawanikana pamawere katundu zovuta zigawo zazikulu mayendedwe zina ziwalo ndi machitidwe thupi.

Choncho, udindo wa chiwindi thupi kwambiri. Komanso Zosefera kunja ndi nayo erythrocytes anawonongedwa ndi hemoglobin, amene ali m'bukuli ntchito monga chuma kwa kupanga ya ndulu. Chifukwa cha njira makutidwe ndi okosijeni zikuchitika mapuloteni, umatulutsa salt ammonium, amene ali poizoni ndithu. Chiwindi otembenuka iwo mu urea omwe si poizoni ndipo excreted kudzera impso.

Chiwindi zimafunika ndi wosakhwima bwino mu thupi la munthu ndi oyang'anira mlingo wa shuga m'magazi. Ngati shuga m'magazi ali ndi kuchuluka muyeso, ndi muyeso kuchedwa chiwindi ndi otembenuka mu glycogen - wowuma nyama. Ngati ndi shuga magazi mlingo osakwanira, chiwindi otembenuka glycogen kumbuyo shuga.

Kotero, inu mukudziwa, kumene mu chiwindi anthu, ndi ntchito yaikulu ndi ntchito yotani. Kusamalira thupi, iye akadali kubwera imathandiza kwambiri.
