Mukati
Mazhinji emakemikari ekusimbisa muviri wemunhu anowana kuburikidza nemudumbu.
Zvisinei, zvokudya zvakajairika zvinodyiwa nevanhu: chingwa, nyama, miriwo - muviri haugoni kushandisa zvakananga kune zvavanoda. Nokuda kweizvi, zvokudya uye zvinwiwa zvinofanira kugoverwa muzvikamu zviduku - mamorekuru ega.
Aya mamorekuru anotakurwa neropa kumaseru ekuvaka maseru matsva uye kugadzira simba.
Chikafu chinozeyiwa sei?
Iyo nzira yekugaya inosanganisira kusanganisa chikafu negastric juice uye kuifambisa kuburikidza nemudumbu. Panguva yekufamba uku, chikafu chinoparadzaniswa kuva zvikamu, izvo zvinoshandiswa kune zvinodiwa nemuviri.
Kugaya kunotanga mumuromo kana uchitsenga uye kumedza chikafu. Uye inoperera mudumbu diki.
Chikafu chinofamba sei kuburikidza nemudumbu?
Nhengo hombe dzakadzika dzemudumbu - dumbu nematumbu zvine mhasuru, izvo zvinoita kuti madziro avo afambe. Iko kufamba kunoita kuti chikafu uye mvura ifambe nemudumbu uye zvigosanganiswa.
Iko kuderedzwa kweiyo gastrointestinal turakiti inonzi peristalsis. Izvo zvakafanana nemafungu ayo nerubatsiro rwemhasuru zvinofamba zvichitevedza hwese hwekugaya.
Iyo mhasuru yematumbo inogadzira chikamu chakamanikana, chiri kufamba zvishoma nezvishoma kuenda kumberi, kusundira chikafu nemvura.
Maitiro ekuzeya
Kugaya kunotanga mumuromo. Paunotsenga chikafu chinonyoroveswa mate. Mate ane ma enzyme anotanga kuputsa starch.
Chikafu chinomedzwa chinopfuura iyo yegurokuro iyo inobatanidza huro nedumbu. Panosangana pahuro nedumbu, pane mhete yemhasuru. Iyi ndiyo yepasi sphincter yegurokuro, iyo inovhura pakamanikidzwa kwechikafu chakamedzwa uye ichichipfuura mudumbu.
Dumbu rine matatu ekutanga mabasa:
1. chengetedzo. Kugadzira huwandu hwakawanda hwechikafu kana mvura, mhasuru dzechikamu chepamusoro chedumbu dzinozorora. Izvi zvinobvumira madziro enhengo kutambanudza.
2. Kusanganisa. Chikamu chepazasi chedumbu chakaderedzwa kuita chikafu uye mvura yakasanganiswa nejusi yegastric. Muto uyu une hydrochloric acid uye enzayemu enzayemu, ayo anobatsira mukuputsika kwemapuroteni. Masvingo emudumbu anoburitsa yakawanda yemamousu, inodzivirira kubva pamhedzisiro yehydrochloric acid.
3. kutakura. Chikafu chakasanganiswa chinopinda kubva mudumbu kupinda mudumbu diki.
Kubva mudumbu, chikafu chinopfuura muchikamu chepamusoro chemukati mudumbu - duodenum. Apa chikafu chinoburitswa muto rwatata uye ma enzyme yemukati ura, iyo AIDS mukugaya kwemafuta, mapuroteni, uye makabhohaidhiretsi.
Pano chikafu chinogadziriswa mubile inogadzirwa nechiropa. Pakati pekudya, bile inochengetwa mukati gallbladder. Ipo ichidya inosundidzirwa mukati me duodenum, umo inosangana nechikafu.
Iyo bile acids inonyungudutsa mafuta ari mukati memukati mezvinhu zvakafanana nezve mafuta kubva mupani: iwo anoputsika kuita madonhwe madiki. Mushure mekunge mafuta acho anyururwa, anotsemurwa zviri nyore nema enzymes muzvinhu.
Zvinhu zvakawanikwa kubva kune zvakapatsanurwa enzymes zvinomedzwa kuburikidza nemadziro emudumbu ura.
Iyo mucosa yemukati mudumbu yakafukidzwa netambo tudiki dzino gadzira yakakura nzvimbo nzvimbo, ichibvumira iyo kuti itore yakawanda nhamba yezvinovaka muviri.
Kuburikidza nemaseru akakosha, izvi zvinhu zvinobva muura zvinopinda muropa uye zvinopararira mumuviri wese kuitira kuchengetedza kana kushandiswa.
Chikamu chisina kugadziriswa chikafu chinosvika mukati ura hukuru mukati inoitwa kunwiwa kwemvura nemamwe mavitamini. Tsvina mushure mekuzeya inogadzirwa muchitsiko uye inobviswa kuburikidza rectum.
Chii chinokanganisa basa remudumbu?
1. Tsika dzakaipa: Kusvuta uye kunwa doro
2. Chikafu chepfu
3. Kusaenzana kudya
Kunyanya kukosha
Iyo nzira yemudumbu inobvumira muviri kupaza chikafu muzvinhu zvakapusa, izvo zvinogona kuvaka nyowani nyowani uye kuwana simba.
Kugaya kunoitika munzvimbo dzese dzemudumbu kubva pamuromo kusvika kuguru.
Zvizhinji nezve iyo yekugaya system basa tarisa muvhidhiyo pazasi:
