ʻO ke kūlana o ka'ōpū liʻiliʻi i ka digestion nui loa a, hiki ke'ōleloʻia,ʻo ka hopena hope loa ia i ka wai o kaʻai i nā mea hope e pono ai no ko mākou kino.
Nāʻikepili nui e pili ana i ka'ōpū liʻiliʻi kanaka
ʻO nā kumu nui o ka'eliʻuʻana i ka hopena liʻiliʻi,ʻo ia ka lā lōʻihi loa, me ka'āpana o kahi kokoke i 200 square meters. Aia ma kēia māhele o ka pūpū o ka lāʻau'onikala ka nui o nā meaola, a me nā poisons, nā toxins, nā lāʻau lapaʻau, a me nā xenobiotics e hoʻohanaʻia e ke ala ākea e hoʻopauʻia. Ma waho aʻe o ka hōʻomiʻana, ka hoʻomohanaʻana a me ka laweʻana i kēia mau mea a pau,ʻo ka hana o ka hoʻonāʻana i ka hormone a me ka pale pale i ke kinona.
ʻO ka pūpū liʻiliʻi e komo ana i nā'okena 3:
- duodenum;
- ka sejunum;
- ka haleum.
Eia naʻe, ma waena o nāʻena i hala hope loa,ʻaʻole he palena kūpono i weheweheʻia.
Hoʻokumuʻia nā paukū o ka'ōpū liʻiliʻi a loaʻa iā ia nāʻehaʻehā:
- mucous membran;
- submucosal;
- maʻi;
- pupuhi.
Pehea ka digestion i loko o ka'ōpū liʻiliʻi?
ʻO ka meaʻai mai ka'ōpū e komo i ka mahele duodenal, kahi e waihoʻia ana i ka bele, a me nā pancreatic a me nā wai'ōpū. ʻO ka digested i loko o nā'ōpū liʻiliʻi kanaka eʻoi aku ka nui o ka mālamaʻana i nā meaʻai, a no lailaʻo ia ka pauʻana o kaʻaiʻana me ke kōkua o ka wai inu waipiu,ʻo ia hoʻiʻekolu mau enzymes. I kēia hihia,ʻeluaʻano o ka hōʻonaʻana i loko o ka'ōpū liʻiliʻi: ka lua a me ka parietal. ʻAʻole e like me ka'ōpala peʻalitic liʻiliʻi ma nā hue liʻiliʻi liʻiliʻi e pili ana i 80% o nā hopena hope loa o ka waiwaiwai a ma ka manawa like ka hoʻomoʻawaʻana i nā mea i pau i kaʻai.
ʻO nā enzymes i hanaʻia e nā hue o ka'ōpū liʻiliʻi e hiki iā ia keʻoki wale i nā kaula liʻiliʻi o peptides a me nā suga, a
Akā,ʻo nā pūnaewele o ka epithelium o ka pūpū liʻiliʻi he mīkini i kapaʻia, a ma o lākou wale nō e kāheleʻia ai nā mea likeʻole, a hikiʻole i nā kinikonaʻole o ka maloka a me ka protein, no ka mea,ʻaʻole hiki ke komo a laweʻia no ka "hana hou".
