Kutalika kwa intestine ndi

The intestine dongosolo m'mimba mwa nyama zimene zili kwambiri. Ziyenera kukhala mwachindunji kumbuyo m'mimba. Mu intestine ndi kalekale chosinkhasinkha ingested chakudya, mayamwidwe a zakudya komanso kuchotsa (kuthawa) undigested zinthu.

Mu nyama zina, kapepala kakuti m'mimba chabe mwa dipatimenti imeneyi. Pankhaniyi, kutalika kwa intestine chimadalira pa mitundu ya nyama, makamaka awo kudya chakudya komanso msinkhu.

The wosazindikira ambiri a dongosolo chatsekedwa wa dipatimenti m'mimba kumachitika mu flatworms ndi coelenterates (atsamunda cnidarians). Yotsirizira ndi umodzi gastrovascular M'mimbamo imene kuwombola zinthu pakati pa munthu amene ali zoyendetsedwa ndi ziwalo zina njuchi. Pa flatworms pali yoyambirira ija kulandira chakudya ndi kuchotsa zinyalala.

Invertebrates (tizilombo, molluscs) adzalandira intestine, wopangidwa mwa magulu atatu (zapambuyo, zapambuyo ndi intestine pakati). Mbali kutsogolo zikuphatikizapo pakamwa, Chotupa chija, pharynx, kum'mero, yomwe ili kumbuyo kwa chotulukira ndi rectum, pakati - Ndipotu, intestine, ziwiya Malpighian, m'mimba. Ena ngale ndi evert intestine. Chimbudzi Choncho anautulutsa.

Mphutsi za lamprey-peskoroek ndi Amphioxus zokwanira mwachindunji ndi yaing'ono intestine. Authority akuyamba yomweyo Akachotsa oropharyngeal. wamkulu lampreys kutalika intestine ndi yaing'ono (zosaposa thupi lenilenilo). Authority akuyamba yomweyo pambuyo kum'mero ali vavu mu mawonekedwe a mwauzimu ndi. Chifukwa ichi kotenga khola kuwonjezeka mayamwidwe ndi chimbudzi m'dera mwauzimu woboola pakati. Mwauzimu vavu alipo ndipo sturgeons ndi nsombazo.

Ambiri peresenti intestine kutalika amalola muchigawane m'zigawo - lachindunji yaikuluikulu intestine. Mu thupi ili anasonyeza zinsinsi za kapamba ndi chiwindi. Kumayambiriro kwa nsomba intestine Bony zili zokhudzana pyloric (njira akhungu). manambala awo angakhale osiyana. Achule ndi a duodenum, ndi cloaca akutsegula rectum.

Land zamiyendo Inayi zokwawa bwino anayamba cecum. Iwo lili kumalire kwa Division yaikuluikulu. Kutalika kwa intestine ndi (woonda) mbalame kangapo kutalika thupi. Ku gulu kumbuyo, yomwe imatithandiza kumveketsa mu cloaca, izo alekanitsa awiri outgrowths akhungu. Rectum ndi m'matumbo muli sangapezeke.

nyama zamiyendo Inayi ndi yaitali intestine zokwanira. Ndime akhungu ndi wandiweyani nthawi yomweyo iwo apanga bwino. m'matumbo kutalika rodent angafikire 53% ya utali wonse wa intestine lapansi. Derali ndi lalifupi kwambiri. Mwachitsanzo, nkhosa intestine, lomwe ndi yaitali kuposa kutalika thupi la 29-35 nthawi Boar - 14, kavalo - 12, ndi Wolf - 6. mafuta unagawanika mu amakhala tizilombo symbiotic, amene ali bwino kwambiri anayamba zamiyendo Inayi.

Intestine anthu ndi yaikulu chiwalo cha m'mimba dongosolo. Umayamba kwa mmimba komanso limatha ndi a chotulukira (chotulukira). chimachititsanso chakudya misa ndi peristalsis (yoweyula ngati contractions). Mu ndondomeko ya chimbudzi zokhudza izo ziri mu thupi la zamoyo ndi amapanga zomera. Izi chimbudzi gawo GIT ikuchitika osati kokha, komanso mayamwidwe zinthu mchere chakudya, kaphatikizidwe mahomoni ena, njira m'thupi.

Munthawi ya moyo wake, kutalika matumbo anthu (wamkulu) ndi anayi mamita. Pobadwa, iye anali pafupifupi atatu mamita, kuti kukula kwambiri wobadwa kumene pafupifupi kasanu ndi kamodzi. M'litali matumbo anthu pambuyo ukuwonjezeka imfa ndi za asanu ndi awiri mamita atatu. Ichi ndi chifukwa cha zosangalatsa a minofu atamwalira.
