Human nhengo kuti kugaya

Zvomudumbu nhengo munhu kuita mumwe yayo inokosha vasiri mabasa - kudya zvokudya, kuichinja simba, kusunungurwa zvokudya uye kuratidza muviri matongo. Ona kuti mabasa aya ose vari zvakanyatsobatana nokushanda kwenhengo imwe nhengo hurongwa anoshanda zvakanaka. Somuenzaniso, mune nedanho kugaya nhengo basa guru iri kweropa ezvinhu munhu - vari kwazvo vakapakata vose zvomudumbu hurongwa. Handiti ropa unowana zvokudya zvinhu uye anotakura navo rose muviri.

yevanhu zvomudumbu maitiro inogona rakakamurwa mhando mbiri - nesekondari. The inokosha avo nechokuita zvakananga womuchato, uye digesting zvokudya kushaya kubva mumuviri. Auxiliary muri shwanu (mate uye rwatata), chiropa, nduru dundira. munhu zvomudumbu izvi nhengo secrete makemikari izvi, pasina izvo kugaya muitiro angadai zvisingabviri.

Sechivako zvomudumbu dzevanhu zvomukati zvakaoma zvikuru, nokuda mabasa avo. Kutanga zvomudumbu maitiro pamwe waiita mhango - pano kunoitika chikuru machine mazino uye zvokudya kunokurumidziswa mate. Parotid mate kusunungurwa, sublingual uye submandibular mate mumasero. Nokushandisa makemikari, izvo huri mate ozeyewa zvokudya, inotanga kare mumuromo - vanonzi kutanga hydrolysis muitiro digesting makabhohaidhiretsi. Next zvokudya anopinda huro, uye ipapo kupinda yegurokuro. Yegurokuro iri kumicheto refu unobatanidza Inlet pamwe mudumbu-wegedhi tsandanyama, kunotadzisa zvokudya Scored kunyika yegurokuro. Kazhinji nzvimbo iyi zvichiri havaratidzi mune vana mumarutsi kakawanda fountain panguva reflux.

Kamwe mudumbu, zvokudya ichipfuura inotevera padanho kugaya. Pane kunoitika hydrolysis kwemapurotini uye mafuta aoma. Kuti kugaya anga qualitatively uye zvakazara dumbu rusvingo secrete chaiyo muchinamatira makemikari zvakadai hydrochloric acid, etc. Kuwedzera dumbu, makemikari zviri secreted uye ebetsero shwanu - rwatata. Mushure zvokudya kwapfuura anodiwa kubudiswa mudumbu, chobudira mugomba ura.

Small ura - mumwe muviri iyo digests chikafu. The duodenum anogamuchira zvokudya zvakananga kubva mudumbu, uye ichi ndipo unorema kubva zvishandiswezve mafuta, zvomudumbu makemikari ari gallbladder, ndima iyo inotanga kupinda duodenum.

Small ura zvokudya mberi, zvose apo kumubata chyme - rinokosha fuma. Kwokupedzisira cleavage Danho kunoitika zvomudumbu zvinhu pamusoro membranes duku ura masero - enterocytes. Pano wefodya unopinda muropa oligosaccharides, amino acids, monosaccharides, mafuta acids. Food residues kuti havagoni kugaya, zvinochinja kuva huru ura. Asi kugaya uye Absorção de Água huru ura asingadi kuitika, asi chikafu dzinongoita wasunungurwa mvura. Zvishoma nezvishoma ozeyewa zvokudya ichichinja mutsvina yadzo. Panguva yokusvika zhomu - gobvu dzeraundi tsandanyama buoyancy mutsvina yadzo nokupira sphincter - uremu anoisa kumanikidza pamusoro intestinal parusvingo uye kunokonzera kunzwa defecation.

Human nhengo kuti kugaya - zvinoshamisa hurongwa, asi panguva imwe chete uye chinonyanya vanoshupika. Ndiwedzere Binaries zvinoenderana iro zvokudya ozeyewa. Zvinosuruvarisa mumadhorobha vagari nokuti basa ravo kazhinji kuenda chikafu kutsanya, machikichori (tichiregeredza siyana), asi zvakakwana asingabatsiri uye dzimwe nguva kunokuvadza chikafu. Kunyange vaGiriki vekare - iye aiziva vakachenjera - vakati: "Isu - chii isu kudya", nokusimbisa kukosha kwezvokudya muupenyu hwomunhu. Ichi chinhu tifunge ...
