Zvomudumbu nhengo: paradzanisa uye kudzidza

Kugaya - mumwe muitiro kuti isu takura mukusaziva, ari mubasa muviri pamusoro dzepanguva chechetere. Ichi kunoomeswa, saka chepamutemo kubvunza kuongorora munhu, "Chiiko kugaya?". Kubva pfungwa nemaonero chiremba, ndizvo zvokudya kubudiswa, zvenyama uye makemikari. Somugumisiro, zvinova zvinoita Absorção de Água kuti zvinhu, uyewo kubvisa tsvina.

zvomudumbu nhengo - akati neburi zvomukati, simbi chinamatidzwa, izvo kubatsira kuputsa makemikari zvisungo zviri zvinhu. Somuenzaniso, mbatatisi chingwa makabhohaidhiretsi uye makabhohaidhiretsi vari muchimiro starch, haagoni kudzidzwa kusvikira starch mamorekuru dzichakoromorwa kuti shuga. Meat mapuroteni uyewo pacharo asingakwanisi nezvairehwa - vanofanira kukura kuti zvinoriumba - amino acids (umo muviri anogona kuvaka yayo mapuroteni). Kwemafuta por Se ingasava mukati muviri svikiro - chete pashure kwazviri nokuda kugaya vari vakawana mafuta acids uye glycerin.

Zvomudumbu Physiology ndechokuti zvinhu izvo, apo mukati muviri, kwete mumuviri zvakatipoteredza. Kuti vaite izvi, vanofanira narwo transformations zhinji. Uye zvino kunoitika kuburikidza mutete mucosal Absorção de Água. Ingestion zvinosanganisirawo chiropa, mate shwanu , uye rwatata. Mukuwedzera, muna rusvingo zvomudumbu zvomukati vane mumasero kuti pave zvakakodzera zvinhu kuti kugaya. All masvingo akafukidzwa madzihwa, nokudaro achidzikisa mukana kuvakuvadza akatunhidzwa nevamwe.

Mechanically chikafu akaitira mazino, ipapo zviri yakavhenganiswa mate. Mate zvitatu yegwara mumasero makuru uye mazhinji maduku vaduku. In ichi mvura zvinoriumba vari makemikari, chicherwa zvinhu uye manyowa zvibereko leukocytes. Asi chikuru chinhu - rine makemikari maviri - ptyalin (musisiri starch) uye maltase (rinotsemuka shuga rye, bhari, etc.). Pamuromo kuburikidza pharynx zvokudya anopinda yegurokuro.

Yegurokuro - the chubhu kuti inogona kunzi zvakanaka yakarurama mutsetse. It yakafukidzwa multilayered squamous epithelium. Masero aya kuramba vari akagadziridzwa, nokuti nyore chaizvo kuti kukuvadza. Fission kunoitika pakadzika akaturikidzana, nepo kwokunze exfoliated uye pasi mudumbu nezvokudya. The submucosa vane shoma kenza - kenza yegurokuro. Around mudumbu, vari zvakafanana fuma kumira panze pamusoro mudumbu, Vanotakura zita cardiac shwanu. Pakutanga yegurokuro mugove striated tsandanyama, asi panzvimbo dzapasi rechitatu chete vane mvere tsandanyama fibers. kumedza kwacho kunotanga nokungwaririra, asi zvino dzava dzepanguva mhinduro. Pashure esophageal kudya ngaakuitirei zvomudumbu nhengo dzakadai mudumbu uye ura.

Dumbu anoita chakanakisisa chisanganiso nokuda tsandanyama kukura. Mumuviri uyu kunotanga mapuroteni cleavage kushandisa pepsin enzayemu, utachiona vanourayiwa hydrochloric acid. Somugumisiro kuti kugaya mudumbu anotendeuka Semi-mvura mukati zvakaenzana wakatemerwa - chyme. Kubva vanonzi Wakanyura panzvimbo imwe munyu mvura, doro, vamwe mishonga. The dumbu unobereka mamorekuru antianemic chinhu.

Kamwe zvokudya anopinda diki ura. Kureba kwayo - avhareji mamita matanhatu. 30 masendimita Chokutanga - the duodenum. Zvinonzi vasiyana pedyo nadzo uye akafamba musoro rwatata. Zvino mberi kuvimba, uye ipapo ileum. In iri ura duku rinopedzisa kugaya uye zvokusarudza zvibereko kugaya vari wefodya unopinda muropa uye node. Muna ura duku vane dzidzo chaiyo - izvo kwazvo kubvisa munharaunda villi,. Mugore ura nokuyerera ducts chiropa (bile) uye rwatata. Somugumisiro, zviri pakupedzisira ozeyewa uye kunyura makabhohaidhiretsi, kwemafuta uye mapurotini. Uye mafuta kuuya zvakananga kupinda node, iyo zvino richibatanidza kuti ropa.

kwakakwana huru ura kugaya residues, asi "pachake" chinonyangadza utachiona. Kunyura mvura, uye zvokudya masarasara kuwana kwemashoko faeces. Wokupedzisira chikamu, mugaranhoko namatongo vachimirira kubviswa muna nedanho defecation. Zvanzi panoperera chirongwa kugaya. Zvakakosha ose zvomudumbu zvomukati, asi basa ravo kwakarongeka kunogona kubatsira masero omuviri uzorodzwe pamberi chivakwa mashoko masero.
