Isisu: isakhiwo. Ukuthatha inxaxheba ekutyeni

Inkqubo ngokubanzi yokutya

Ukuze kugcinwe i-metabolism evamile, umzimba womntu ufuna ukuhlaziywa rhoqo kwezixhobo ezichithwe ngendlela ye-organic compounds, iivithamini, i-macro-microelements. Iprogram yokuphefumula ihambisa kuphela iimlekyuli eziqulethwe emoyeni, zonke ezinye i-substrates umntu ezamkelwa ngoncedo lwenkqubo yokutya. Nangona kunjalo, ukuba iinkqubo zokuxhamla zivela emathunjini kunye nxalenye emgodini womlomo, ukucwangciswa kwemichiza kunye neekhemikhali yokutya okufunyenweyo kuqhutyelwa sisisu. Isakhiwo seendonga ziqinisekisa ukuhlukana kwama-macromolecules zibe ziincinci ezincinci ukuze kugcinwe kakuhle kwi-intestine kwaye kukhuthaze i-chyme kwisigxina esiswini. Nangona kunjalo, kwimeko engummangaliso yile mzimba, i-enzymes ejongene nokucoca kwe-carbohydrates ayinakwenziwa, ngoko emva kokuphuma kwendawo yokutya kwenkqubo eqhubekayo yekhemikhali iyaqhubeka kwi-duodenum. Oku kuvimbela ukuphindwa kwe-chyme kwakhona kwisisu: isakhiwo se-sphynctrum yesibini sinokuncitshiswa ngokukhawuleza emva kokuphela kokuphuma. Kwaye ngexesha lokuba izondlo zifike emathunjini amancinci, phantse zonke ziya kuhanjiswa ngendlela ye-dimers, i-monomers kunye ne-ions ezinokudlula emathunjini emathunjini kunye nokunyuka egazini.

Ulungiswe njani?

Isakhiwo sesisu somntu sinokumelwa ngesimo sesigxoba esisisigxina esineziqendu ezibini: i-cardiac (kuquka i-vestibule, ezantsi kunye nomzimba) kunye ne-pyloric (equkethe i-pylorus cave and canal sequentially located). Okulandelayo, oku kuthethwa nge-lumen ye-duodenum. Kwaye ukuqinisekisa ukuhamba kakuhle kokutya kwiphecana, isisu sinesiphene ezimbini: i-gastroesophageal, ekhusela ukubuyela kwi-esophagus, kwaye m. I-Sphincter pylori, ekhusela i-duodenum kwi-medium acidic esesisu. Isakhiwo sodonga lwayo kuquka ukufaka iiseli. Zenza i- hydrochloric acid ngokunyanisekileyo ukuba zivule amaprotheni, zenze i-enzymes, zibulale izinto ezithathelwanayo kwindawo yokutya kwaye ziqale ukuphuma kwayo. Kwakhona la maseli adibanisa kwaye abizwa ngoko. Inqobo yangaphakathi yeNqaba, enomsebenzi onxamnye nomdla.

Amagama ambalwa malunga nabanye

Iiseli zeparietal zesisu zivelisa i-pepsinogens, kunye ne-mucocytes - i-mucus, ukudala umqobo wendalo ngokumalunga ne-HCl kwisisu. Isakhiwo sodonga lwama-muscular sine-three layered: i-myocytes ine-longitudinal, transverse and oblique direction. Bakhombisa umsebenzi omkhulu kunomntu omileyo kunye no-zero-kwiindawo ezibuxoki. Kwakhona, i-peristalsis ivuselelwe ukuxhatshazwa kwemisipha yesicindezelo esiswini. Ngaloo ndlela, isakhiwo nemisebenzi yesisu kubaluleke kakhulu kwinkqubo yokugaya. Ngako oko, ngokuchithwa ngokukodwa kwalolu lungu okanye i-hyper / i-hypo / asecretion ye-hydrochloric acid kunye nesantya sesisu, onke amanyathelo athile ayavalwa - kwaye kukho isifo se-dyspepsia esiswini. Yaye ukuba iinkqubo zithintelo, i-gastritis iyaqhubeka, kwaye kamva isisu sesisu.
