Zokwawa nyama dzina lawo chifukwa cha chikhalidwe cha kayendedwe ka padziko lapansi. Iwo mwina alibe kapena miyendo yaifupi, amene anakonza mu ndege yopingasa. Choncho, ngati "groveling" pansi. Onsewo ali mwankhanzaku nyama zimene katswiri ndi madzi, ndipo malo lapansi. Koma chitukuko cha mazira, amene amacheza ndi chipolopolo zoteteza dzira kumachitika kwathunthu dziko. chokwawa thupi yokutidwa ndi mamba youma tentha mthupi.

Zinthu zofunika ndi maonekedwe a dongosolo mkati mwa chifuwa izi kupuma yekha m'mapapo mwanga, umuna mkati ndi zokwawa excretory dongosolo, kudzera mwa impso, chikhodzodzo ndi cloaca.

dongosolo m'mimba: m'madipatimenti chachikulu

Dongosolo m'mimba zapoizoni ankaimira thirakiti zopangitsa apadera. Mosiyana achule, mwa nyama zimenezi ndi zopangitsa malovu yotulutsa michere. zinthu zachilengedwe ndi kwachilengedwenso catalysts. Iwo gwirizana pankhani zovuta organic mu yosavuta. Mu njira imeneyi iwo akhoza odzipereka anaonetsera mu malo. Kapangidwe zokwawa dongosolo m'mimba amadziwikanso yodziwika ndi kukhalapo kwa mano undifferentiated ndi cecum. Izi ndi zinthu zofunika cha kapangidwe poyerekeza achule.

zokwawa chimbudzi lili mkamwa, pharynx, yopapatiza kum'mero, m'mimba ndi intestine. Last kusiyanitsidwa ndi tichipeza m'madipatimenti ang'ono ndi lalikulu, kudutsa mu cecum ndi. Itha m'mimba chubu cloaca. Ichi ndi kutsegula kudzera amene kuoneka osati nepererevarennye chakudya zotsala, komanso mankhwala a dongosolo excretory ndi ubereki wabwino wa zokwawa.

Monga tanenera kale, kachitidwe excretory zapoizoni amakhala ndi zina zosokonezeka. Ngakhale kuti mano onse M'mimbamo oropharyngeal ali yemweyo yekha kutumikira kugwila ndi kugwira nyama, kumeneko spetsialirovannye. Mwachitsanzo, njoka zaululu. Anthu ambiri amakhulupirira kuti kutilepheretsa nyamazo mothandizidwa ndi chinenero. Koma si choncho. Izi M'mimbamo m'kamwa chakupha dzino, momwe pali njira ndi chinthu poizoni. Ndipo ku nsagwada za zolusa monga ng'ona, ndi kubudula kosatheka, chifukwa mano ndi amphamvu kwambiri ndi akuthwa. Mwachitsanzo, masamba a nyama kawirikawiri "ntchito" kuti zosiyanasiyana mpaka makumi angapo nthawi pa chaka. Mwa njira, mosiyana ndi achule, ndipo ambiri mwa chinenero chiwalo cha adani a chakudya, thupi krokodidov pafupifupi zinaphatikizidwa ndi patsinde pa kamwa, Zikuonekanso kuti si konse.

m'mimba dongosolo ntchito zokwawa

M'mimba dongosolo kuthetsa cholinga chimbudzi ndi mayamwidwe zakudya. Pa pogawanikana pamawere awo allocated wina kuchuluka kwa mphamvu ntchito ndi zamoyo kwa ndondomeko zonse zofunika. Pamene pogawanikana pamawere izi zichitika kudzera mwa michere apadera zopangitsa, ndi kayendedwe ka particles chakudya kuchokera M'mimbamo m'kamwa kuti agwire cloaca thirakiti minofu khoma.

Choncho, dongosolo m'mimba ali zokwawa monga mmene mbali structural wa chordates, ndi zina zapadera. Zikuonekeratu kuti poyerekeza ndi achule, ndi ovuta kwambiri kupeza. Izi anawonetseredwa mu kukhalapo kwa michere m'mimba amene anamasulidwa ndi zopangitsa apadera, cecal ndi matumbo zosiyanasiyana.
