Kureba ura

The ura ndiyo zvomudumbu wemuTesitamende vertebrates dzakawanda. Zvinofanira kuva zvakananga shure mudumbu. Muna ura ari digesting anwa zvokudya zvachose, kuti Absorção de Água muviri uyewo kubvisa (kubvisa) undigested zvinhu.

Mune dzimwe mhuka, zvomudumbu turakiti rinongova kunze wedhipatimendi ichi. Panyaya iyi, nokureba ura kunoenderana mhando dzemhuka kunyanya zvokudya zvavo kudya uye zera.

The kupfuura chinyakare pamusoro namahwindo nemamiriro zvomudumbu dhipatimendi kunoitika muna flatworms uye coelenterates (yaitonga cnidarians). Ekupedzisira vane chete gastrovascular mhango kuburikidza icho kupanana zvinhu pakati munhu uko dzinofambiswa, uye dzimwe nhengo yaitongwa. At flatworms pane buri rimwe kugamuchira zvokudya uye kubviswa tsvina.

Invertebrates (zvipembenene, molluscs) nhaka ura, iine mumapoka matatu (Anterior, posterior uye pakati ura). Nechemberi inosanganisira muromo, goiter, pharynx, yegurokuro, riri pasuo rwemberi horo uye mugaranhoko, pakati - Chokwadi, ura, Malpighian nemidziyo, dumbu. Vamwe korari vane Evert ura. Saka kugaya kunze.

The mazana of lamprey-peskoroek uye Amphioxus vane zvakakwana zvakananga uye diki ura. Authority paanotanga pakarepo mushure oropharyngeal mhango. vakura lampreys Kureba ura iri diki (hapana kupfuura muviri pachayo). Authority paanotanga pakarepo pashure yegurokuro ane vharafu ari muchimiro zononoka. Nokuda ichi zononoka serin'i longitudinal nedanga kuwedzera Absorção de Água uye kugaya nharaunda. Spiral vharafu aripo uye sturgeons uye Sharks.

Vazhinji vertebrate ura urefu kunoita kuti mugovane muzvikamu - zvakananga, zvikuru nezviduku ura. Mumuviri uyu anonyorwa zvakavanzika rwatata uye chiropa. At pakutanga ura mhou hove dziri pyloric zvinoshandiswa (bofu pezvakaitwa). nhamba yavo angava akasiyana. Amphibians ndiwo ari duodenum, uye cloaca anovhura mugaranhoko.

Land herbivorous zvinokambaira kunge zvakanaka dzakabudirira cecum. It riri pamuganhu huru neduku Division. Kureba ari ura (dzakaonda) shiri kanoverengeka muviri pakureba. Neshure kupesana, iyo inotanga kupinda cloaca, anoparadzanisa maviri outgrowths mapofu. Mugaranhoko uye muura usipo.

mhuka Herbivorous vane refu ura zvakakwana. Bofu uye gobvu zvikamu panguva chete ivo vakava kwazvo nguva. muura urefu rodent anogona kusvika 53% of zvachose kureba ura. Zvikara zviri mapfupi zvikuru. Somuenzaniso, gwai ura, izvo kunopfuura muviri kureba 29-35 kakapetwa musii - 14, bhiza - 12, uye Wolf - 6. The mafuta vakaparadzana mune anogara symbiotic tupukanana tusingaoneki, vane dzakasimukira zvikuru kwazvo herbivorous.

Ura nevanhu ndicho chikamu chikuru reDare zvomudumbu hurongwa. Rinotanga kubva mudumbu uye rinopera chete horo (horo). Food vakawanda inofamba nenzira peristalsis (wave-kufanana sunga). In nedanho kugaya vanobatanidzwa, zviri mumuviri zvipenyu uye kunganzi nemiti. Izvi mugove Git kugaya rinoitwa kwete chete, asiwo Absorção de Água kuti chicherwa zvinhu kubva zvokudya, kubatana kwetunhu zvimwe mahormone, masoja kwendangariro.

Muupenyu hwake, kureba ura muvanhu (akura) anenge mana mamita. Pakuzvarwa, akanga anenge matatu metres, kuti zvimwe achangoberekwa kukura mune avhareji katanhatu. Kureba dzevanhu muura pashure pokufa kunowedzera uye anenge manomwe mamita masere. Izvi nokuda kutandara tsandanyama pashure porufu.
