Isisu: isakhiwo. Ukuhlanganyela ukugaya

Isikimu jikelele ukugaya

sokuvuselela njalo kwezinsiza ziqedwe uhlobo organic compounds, amavithamini, macro- futhi microelements umzimba womuntu kudingeka silondoloze umzimba evamile. uhlelo zokuphefumula eletha kuphela amangqamuzana eziqukethwe emoyeni, kanye asele substrates umuntu uthola nge isimiso sokugaya ukudla bungene. Nokho, uma izinqubo absorptive zenzeka amathumbu kancane kule ngalo ingaphakathi ngomlomo, ukuphathwa mechanical futhi amakhemikhali ukudla kutholakala uqhuba isisu. Isakhiwo kwezingange zawo kwenza cleavage ka macromolecules zibe izicucu ezincane ukugaya kangcono emathunjini, futhi ukhuthaza chyme kuya Git ecashile. Nokho, imvelo azibukhali umzimba okunqanda enzyme obangela ukuwohloka carbohydrate, ngakho ngemva kokuphuma kusukela bolus akhe aqhubekayo yezinqubo zamakhemikhali ezenzeka duodenum. Lokhu kuqinisekisa ekuvimbeleni regurgitation chyme emuva esiswini: isakhiwo sphincter yayo yesibili ivumela encishisiwe ngokushesha ngemva esiphuthumayo. Futhi ngesikhathi izakhi ukufinyelela emathunjini amancane, cishe bonke of them izokwethulwa ngesimo dimers, monomers futhi ion izophela ngokusebenzisa villi emathunjini futhi angena egazini.

Indlela okusebenza?

Ukwakheka esiswini umuntu kungenziwa umelwe eziyize isikhwama kwemisipha ukwehlukana ezimbili eziyinhloko: inhliziyo (kuhlanganise egumeni, phansi futhi umzimba) kanye pyloric (ehlanganisa ngokulandelana emhumeni pyloric nesiteshi). Ngaphezu kwalokho, umyalo wokugcina baxhumana duodenum. Futhi ukuqinisekisa ukukhuthazwa efanele ukudla ngokusebenzisa leli pheshana esiswini has ezimbili sphincter gastro kuvimbela ukubuya emphinjeni, futhi m. sphincter pylori, Guardian duodenum kusukela imvelo esidi, okuyinto esiswini. Isakhiwo kwezingange zawo yakhiwa parietal amaseli. Amemezela ngentshiseko ukukhiqiza hydrochloric acid ukuze ukuvuvukala amaprotheni, ama-enzyme kusebenze, ukubhujiswa infekta okuqukethwe isisu bese uqale ukuthuthwa kwabantu ngenxa yengozi yayo. Futhi, la mangqamuzana synthesize futhi okuthiwa biermerin kokuba umsebenzi protivoanemicheskim.

A kancane mayelana nezinye

Esiswini parietal cell akhiqiza pepsinogen, futhi Mucocytes - isikhwehlela, okuyinto sakha umgoqo yemvelo ngokumelene isenzo HCl esiswini. Isakhiwo odongeni kwemisipha ezintathu ungqimba: myocytes babe longitudinal, transverse kanye izinkomba etshekile. Umsebenzi enkulu bona abonise ngesikhathi ukuma indoda futhi cishe zero - kule sikhundla lisalele. Futhi phezu motility inkanuko ithonya imisipha ukungezwani abdominals. Ngakho, isakhiwo kanye umsebenzi esiswini kukhona libaluleke e inqubo ukugaya. Ngakho-ke, uma lokhu resection esinqunyiwe noma isitho hyper- / Hypo / asekretsii hydrochloric acid esiswini juice block zonke izinyathelo eminye - futhi esiswini dyspepsia syndrome kwenzeka. Isithiyo indlela lapho ukwehluleka eba kolwelwesi, futhi eminye futhi isilonda esiswini.
