Gastropods: zvemukati mamiriro

Zvomudumbu hurongwa anotanga dzaiita zvokutaurwa mhango, kuvhurika iyo unongoda pamusoro underside musoro nharaunda. The huro chinhu chaicho repamutemo rinonzi radula, inova chitin grater izvo zvokudya wapera uye anopinda yegurokuro. Next anouya mudumbu (pano rakazaruka hepatic ducts) uye ura, kupedza gomba.

The excretory maitiro dzakawanda zvipenyu raimiririra imwe itsvo, kunyange pane mhuka, uye nemiviri maviri. The kweropa Hurongwa zvinoreva lacunarity mhando uye ine mwoyo uye vascular hurongwa maburi.

Respiratoria hurongwa aimiririra gills kana nemapapu. Marine Vamiririri, sezvinoita mutemo, unogona kuonekwa ctenidium kana chikuru gills. In chete kwemarudzi kuti vakatamira kechipiri mvura kurarama, dakashwa basa anotora nejasi. Vamiririri Ground vari dzinoratidzwa zvikuru kunzwisisa kufema ezvinhu, chine munhu lightweight ino uye tracheal sepombi, izvo diverges uye anotakura mhepo yose nhengo dzomuviri.

Well akaumba uye tsinga, riri kunzi diffuse-raiva pedyo nebundu mhando. mhuka Most vane majoko mashanu zvinokosha ganglia. Zvinokosha kucherechedza uye zvakanaka kunyatsobudirira pfungwa nhengo, kusanganisira maziso uye tactile receptors.

Gastropods ingava dioecious (zvomumvura marudzi) uye hermaphrodites (nyika uye Freshwater nevamiririri). Muchangosangana Kazhinji kunoitika mumuviri munhukadzi, ipapo iye mazai aro. Zvinofadza kuti pane imwe nguva gastropod mazai akawanda panguva kamwe, pova batira.
