'Ihe'ia i loko o kahi hāpapa waha

'O ka hō'ino'ana i ka'ai he hana ma'alahi ia e ho'onā iho i ka māhele'ana o nā molecuka nunui o nā protein, nā momona a me nā carbons i monomers e ma'alahi i nā pūnaewele o ke kino. Ma nā wahi like'ole o ka'ōpala pahū, ho'opau'ia nā'ano like'ole o ka pūnaewele, a laila ho'okomo'ia i loko o ka mucosa intestinal li'ili'i a ho'olaha i loko o ke kino. Ho'omaka i ka'ai'ana i loko o ka waha.

Ma mua o ka noonoo ana i ka digestion i loko o ka waha, pono e ma ka liʻiliʻi loa ka hua olelo ike a me kona 'ole.

Ka ho'onohonoho'ana i ka'alū waha

Ke 'anatomia i hiki ke maheleia ku una lua i mau papa elua:

• 'O ka paepae o ka waha (ka manawa ma waena o nā lehelehe a me nā niho);
• 'O ke'ano kūlohelohe waha (i palena'ia i nā niho, nā iwi āpau a me ka diaphragm o ka waha);

'O kēlā me kēia māhele o ka pae ha'i waha he mea pono'ī kona pono a'o ia ke kuleana no kekahi mau hana o ka mea'ai.

'O nā kekona ke kuleana no ka hana mechanical o nā mea'ai ma'amau. Me ke kōkua o nā canines a me incisors kanaka nahu ai, alaila uuku molars kona crushes. 'O ka hana o nā mola nui'o ka'ō'ō hua.

'O ke alelo kekahi'āpana musopa nui e pili ana i ka lalo o ka waha waha. 'A'ole pili ka'ōlelo ma ka hana'ana i nā mea'ai wale nō, akā ma nā'ano o ka'ōlelo. 'O ka hele'ana, ua hui pū kēia muscular organ i ka mea'ai me ka'ala a hana i kahi'ūpena'ai. Eia kekahi, aia i loko o nā'ene o ke alelo ka mea'ono, ka mahana, ka'eha, a me nā mea e loa'a ai nā mechanical.

Hiki i nā kī'aha Salivary - parotid, sublingual and submaxillary ke kī o ka waha me ke kōkua o kahi le'a. 'O kā lākou hana nui,'o ia ka hana a me ka ho'onanee o ka pala, a he mea nui loa ia no ka hana'ana i ka hō'ino'ana. 'O nā hana hana ma'amau penei:

• 'O ka'ale'a (loko o nā'elemu, kahi e pipili'ia ai nā'ale'a);
• 'O ka pale (loko o ka palaka he lysozyme, kahi loa'a nā'ano bactericidal ikaika, a me ka pala'a nā māmālolobulins a me nā kumu coagulation.) Mālama ka'ewa i ka'awa'u waha mai ka ho'omalo'o'ana);
• 'O ka'olu'olu (me nā mea'ala e like me ka uruta, ka pa'akai, ka wai'ona, kekahi lā'au lā'au);

'O ka'eha i loko o kahi pae waha: mechanical phase

Ma ka waha waha, hiki i nā'ano mea'ai he nui ke komo a ma muli o kona kūlike, e hele koke ana i loko o ka esopha i ka wā e inu ai (inu, mea'ai wai), a hana'ia paha ka hana mechanical e ho'oponopono hou ai.

E like me ka mea i ha'i mua'ia, me ke kōkua'ana o nā niho, ua'eha ka'ai. Pono nā'āpana o ke alelo e ho'ohui i nā mea i ma'a me ka pala. Ma lalo o ka mana o ka pala, ho'onanea ka mea'ai a ho'opili i ke kī. 'O Mucin, ka mea i loko o ka'ala, ke komo i ka hana'ana i ka'ūpū'ai, a ma hope aku e komo i loko o ka hale.

'O ka'eha i loko o kahi hāmama waha: ka manawa enzymatic

I ka haku mele 'ana o ka tuha kekahi a me kekahi nā'ūhū i ka pae'āina ma ka decomposition o polymers i komo. Ma ka waha o ka waha, aia ka mahele'ana o nā carbons, e ho'omau'ia nei i loko o ka'ōpū li'ili'i.

Loa'a ka'alapalapa he pa'akikī o nā enzymes i kapa'ia ka ptyalin. Ma lalo o ko lākou mana, ho'ohemo nā polysaccharides i nā mea kū'ē ('o Maltose ka nui). Ma hope, maltose ma lalo o ka mana o kekahi enzyme e māhele'ia i ka glucose monosaccharide.

'O ka lō'ihi o ka'ai i loko o ka hāmama o ka waha a hiki i ka hana enzymatic,'o ka ma'alahi ka'eli'ana ia ma nā wahi'ē a'e o ka māla li'ili'i. 'O ia ke kumu i'ōlelo pinepine ai nā kauka i ka'ai'ana i nā mea'ai i ka lō'ihi.

Ma ka pau'ana o kēia'ai'ana i ka waha. Ho'omo'a'ia ka'ūpī'ai, a ho'omaka i ke kumu o ke alelo, ho'omaka ka'ōmole e ho'oluliluli i ka hana, kahi e hele ai ka'ai i loko o ka'ōpū a komo i ka'ōpū.

Inā hiki ke hō'ulu'ulu'ia, a laila, ma ka waha o ka waha, kahi hana e like me ka'ōwili'ana i ka mea'ai, ka nānā'ana i nā mea'ono, ka mīkini me ka pala'a, me ka ho'ohui'ana a me ka hā'ule mua o nā ha'alulu.
