Anthu chiwindi: kapangidwe ndi ntchito

chiwindi anthu ndi udindo chitukuko cha mankhwala atsopano ndi n'chongoletsa poizoni ndi mankhwala a kagayidwe mu thupi. ntchito zimenezi n'zofunika kwambiri.

Malo a chiwindi anthu limafanana ndi kayendedwe ka magazi matumbo, limene likutengera zakudya. zinthu izi odzipereka kwa zakudya chakudya. Choncho, kubwerera ku mtima ndi mapapo ku magazi m'mimba, ndi dongosolo kale venous kutsogolera chiwindi.

Ili mwachindunji pamwamba thupi la chifundamtima. chiwindi anthu atetezedwe ku nthiti za m'munsi zisaonongeke. M'mikhalidwe yachibadwa iyo siingakhoze anamvera. Komabe, ndi maziko a matenda ena pali kuwonjezeka mu thupi, ndipo, pamene inu tilimbikire pamimba ndi mosavuta zimadziŵika.

Kapangidwe ka chiwindi anthu

chiwindi ndi waukulu mu thupi. chiwindi anthu ali ndi kulemera kwa kuchokera makilogalamu 1,36 kuti 1,81.

Mu thupi kusiyanitsa awiri yotundumukira kunja kwa mpanda m'deralo. The Lobe lamanja la chiwindi kuti ndi ili kudutsa pamwamba pa mbali ya peritoneum ndi ziwalo. Chakumbali ya (m'munsi) dera umalandira pakati kumanzere.

maselo limba kugwira ntchito pa mlingo tosaoneka ndi maso, potero kupereka ndondomeko zofunika kwambiri moyo. iwo amatchedwa "hepatocytes" Mu terminology zachipatala. ntchito yawo chikugwirizana ndi zinthu zazikulu: mafuta, mapuloteni ndi chakudya. Popanda zinthu izi thupi kulibe.

Mapuloteni kwambiri mogwirizana ndi chotenga mbali mu chilengedwe ndi kubwezeretsa maselo, mapangidwe mahomoni, kukula kwa michere.

Chakudya umaimiridwa ndi gulu lalikulu la mankhwala. Iwo amakhala ndi atatu maatomu: hayidirojeni, carbon ndi oxygen. Chakudya mtima mu shuga yogwirizana mitundu. Mmodzi wa iwo - shuga, ndipo chachiwiri - glycogen. Kupanda shuga m'magazi ndi kungasokoneze kwambiri pa ntchito kwa ubongo. Ndipo overabundance ake akhoza kusungidwa mu mawonekedwe a glycogen.

Chinanso chofunika kwa thupi ndi mafuta. chiwindi anthu otembenuka iwo mu njira yabwino kwa ayambe minofu adipose, wosanjikiza subcutaneous. Komanso, mankhwala ndi njira zosamalira mphamvu.

Vienna wosanjikiza chimakwirira maselo wapadera (Kupffer) akuchita ntchito zingalowe kuyeretsedwa magazi kuchokera mabakiteriya. Komanso, kutenga zosafunika corpuscles ofiira ndi kupereka kwa processing wa hepatocytes.

Mu kusinthika ndi byproducts amapangidwa. Makamaka, amoniya ndi chinthu poizoni. maselo chiwindi n'chongoletsa izo. Ici ulikubala mankhwala otetezeka - urea - kubwerera m'magazi. Kagayidwe mafuta ndi magazi anasonyeza mu mawonekedwe a ya ndulu.

Kuti tikhale ndi ntchito zonse za ntchito ndi kupereka mphamvu kwa zimakhala thupi chofunika otaya azilandira shuga. Pa mlingo wake wotsikitsitsa mu pogawanikana pamawere chakudya ndipo anapanga mapuloteni yaitali. Chifukwa mowa mofulumira mapuloteni mu zimakhala zambiri masiwichi ntchito mu mawonekedwe a gwero zina katundu mafuta chimbudzi. mankhwala amenewa amatchedwa "ketones".

Ndi wopanda shuga amapangidwa ndi kusamutsidwa kwa chiwindi ku mafuta minofu. Ketone matupi, ataima panja kufalitsa zokhudza zonse yomweyo anayamba kugwiritsidwa ntchito ndi minofu, ubongo, mtima ndipo zimakhala zina monga gwero mphamvu.

Tsiku lililonse, chiwindi amatulutsa ya ndulu pafupifupi lita. mankhwala lili ndi chiwerengero chachikulu cha zigawo mankhwala. Ya ndulu zochitika pa chimbudzi cha mafuta, ndi mbali ya chitetezo cha excretory.

Chiwindi ndi chimodzi mwa ziwalo zofunika kwambiri. Komanso, iye ali nawo njira kagayidwe kachakudya, ntchito yake ndi zosefera magazi ndi kuteteza mapangidwe ya ndulu, njira m'mimba.
