ʻO ka hapa nui o nā meaola e mālama ai i ke kino o ke kanaka e loaʻa ma o ka gastrointestinal tract.
Eia nō naʻe, nā meaʻai maʻamau a ka poʻe e ʻai ai: ka berena, ka ʻiʻo, nā mea kanu - ʻaʻole hiki i ke kino ke hoʻohana pololei no kā lākou pono. No kēia, pono e hoʻokaʻawale ʻia ka meaʻai a me nā mea inu i nā ʻāpana liʻiliʻi - nā mole āpau.
Lawe ʻia kēia mau molekiola e ke koko i nā hunaola no ke kūkulu ʻana i nā hunaola hou a hana i ka ikehu.
Pehea ka ʻai o ka meaʻai?
ʻO ke kaʻina hana o ka digestion pili i ka hoʻohuihui ʻana i ka meaʻai me ka wai ʻōpū a neʻe iā ia ma o ka gastrointestinal tract. I kēia neʻe ʻana, hoʻokaʻawale ʻia ka meaʻai i nā ʻāpana, i hoʻohana ʻia no nā pono o ke kino.
Hoʻomaka ka ʻai ʻana i ka waha i ka nau ʻana a me ka ale ʻana i ka meaʻai. A pau i ka ʻōpū liʻiliʻi.
Pehea e neʻe ai ka meaʻai ma o ka digestive tract?
ʻO nā ʻāpana hakahaka nui o ka gastrointestinal tract - ka ʻōpū a me nā ʻōpū i kahi huna o kaʻiʻo, kahi e neʻe ai ko lākou mau paia. ʻAe kēia neʻe i ka meaʻai a me ka wai e neʻe ma waena o ka ʻōnaehana digestive a kāwili ʻia.
Kāhea ʻia ka hōʻemi ʻana o ka gastrointestinal tract ʻōlima. Ua like ia me ka nalu me ke kōkua o nā mākala e neʻe ma ke kaʻina digestive holoʻokoʻa.
Hoʻokumu nā mākala o nā ʻōpū i kahi ʻāpana paʻa, kahi e neʻe mālie nei i mua, kaomi ʻana i ka meaʻai a me ka wai.
Ke kaʻina hana o ka digestion
Hoʻomaka ka ʻai ʻana i ka waha. Ke nau ʻoe i ka meaʻai ua mākū nui ia me ka lawai. Loaʻa i ka saliva nā enzymes e hoʻomaka i ka haki starch.
Hele ka ʻai i ale ʻia i loko ka esophagus i hui pū ka puʻu a me ka ʻōpū. I ka hui pū ʻana o ka esophagus a me ka ʻōpū, aia ke kani o ka mākala. ʻO kēia ka sphincter o lalo o ka esophagus, i wehe ʻia ma ke kaomi o ka meaʻai i ʻai ʻia a hāʻawi ʻia i loko o ka ʻōpū.
Loaʻa i ka ʻōpū ʻekolu mau hana maʻamau:
1. pūnaewele. E hana i kahi nui o ka meaʻai a wai paha, hoʻomaha nā mākala o ka ʻaoʻao luna o ka ʻōpū. ʻAe kēia i nā paia o ka meaola e hoʻolōʻihi.
2. Kāwili. Hoʻoemi ʻia ka ʻaoʻao haʻahaʻa o ka ʻōpū i ka meaʻai a me ka wai i kāwili ʻia me ka wai ʻōpū. Aia kēia wai i ka acidchchloric acid a me nā enzyme digestive, kahi e kōkua ai i ka haki ʻana o nā protein. Hūnā nā paia o ka ʻōpū i ka nui o nā mucus, kahi e pale ai iā lākou mai nā hopena o ka waikawa hydrochloric.
3. ka halihali. Komo ka meaʻai kāwili ʻia mai ka ʻōpū i loko o ka ʻōpū liʻiliʻi.
Mai ka ʻōpū, hele ka meaʻai i ka ʻāpana kiʻekiʻe o ka ʻōpū liʻiliʻi - ka duodenum. Ma aneʻi e hōʻike ʻia ka meaʻai i ka wai momona o ka pancreas a me nā enzymes o ka ʻōpū liʻiliʻi, ʻo ia ka maʻi ʻaʻai i loko o ka digestion o nā momona, nā protein, a me nā haʻuki.
Maʻaneʻi e hoʻoponopono ʻia ka meaʻai i ka bile i hana ʻia e ke ake. Ma waena o nā meaʻai, mālama ʻia ka bile gallbladder. ʻOiai e ʻai ana ua kīloi ʻia i loko o ka duodenum, kahi e kāwili ʻia ai me ka meaʻai.
Hoʻopau nā waikawa o ka bile i ka momona i loko o nā ʻōpū o nā mea like me ka momona mai ka pā: haki lākou i mau kulu liʻiliʻi. Ma hope o ka ʻeli ʻia ʻana o ka momona, mahele maʻalahi ʻia e nā enzyme i nā ʻāpana.
Hoʻokomo ʻia nā mea i loaʻa mai nā ʻākoakoa mahae ma o nā paia o ka ʻōpū liʻiliʻi.
Uhi ʻia ka mucosa o ka ʻōpū liʻiliʻi me nā olonā liʻiliʻi e hana i kahi ākea nui, e ʻae ai e omo i ka nui o nā meaola.
Ma o nā hunaola kūikawā, komo kēia mau mea mai loko mai o ka ʻōpū i ke koko a pāhola i ke kino no ka mālama a hoʻohana ʻana paha.
Hiki mai ka hapa o ka meaʻai ʻole i hoʻoulu ʻia ka ʻōpū nui i loko kahi e lawe ai i ka wai a me kekahi mau wikamina. Hana ʻia nā ʻōpala ma hope o ka digestion i loko o ka pahu a hemo ka ʻūhā.
He aha nā mea e hoʻopōʻino ai i ka hana o ka gastrointestinal tract?
1. Nā ʻano maikaʻi ʻole: Puhi paka a me ka inu ʻana i ka waiʻona
2. Ka lāʻau make ʻai
3. ʻAi kaulike ʻole
ʻO ka mea nui
Hāʻawi ka gastrointestinal tract i ke kino e wāwahi i ka meaʻai i nā mea maʻalahi, hiki ke kūkulu i nā mea hou a loaʻa ka ikehu.
Hana ʻia ka ʻai ma nā ʻāpana āpau o ka gastrointestinal tract mai ka waha a i ka ʻūhā.
ʻO nā mea hou aʻe e pili ana i ka ʻōnaehana digestive e nānā i ka wikiō ma lalo:
