Mhando sandara makonye, kunyanya kwokunze uye zvemukati marongerwo

Type Flatworms ine vasiri parasitic uye parasitic siyana. In ichi vakasununguka-zvipenyu ikashandiswa imwe kirasi, uye avo vanorarama tichiregeredza zvimwe zvipenyu, - matanhatu. Kirasi Vamiririri Ciliated (Planaria turbellarians) vanogara miviri mvura, kazhinji ndivo nezvikara.

Parasitic flatworms kurarama mumuviri mhuka uye vanhu. dhata Utachiona vari dzakashandisa zvakanaka izvi zvinhu zvoupenyu, kuti. kuti. vane Kuziva, izvo vasiyana madziro zvomukati vehondo, uye segmented muviri ane-inoramba ichiwedzera zvikamu. Ivo vanoonekwa ne pasina zvomudumbu ino (kunze kirasi Flukes), zvokudya zviri woga nomuviri kuburikidza dzinokosha outgrowths; anaerobic afemeruke (navanofemereka ari substantially okisijeni isina ezvinhu), uye kuwanda (vari hermaphrodites).

Zvose izvi zvinhu inobvumira nhengo iyi kugara zvachose mumuviri hondo uye uve mari yake. helminths izvi zvinosanganisira: chiropa fluke, remenets, katsi fluke, nyama yenguruve tapeworm, Echinococcus, etc. Kuti abate murume wavo anogona, kana achidya mbishi kana taita zvakaipa mombe nyama, nyama yenguruve, uye hove ..

Type Flatworms Chine Utachiona zvakafanana features, zvose kwokunze uye zvemukati marongerwo. Dzinomirira bespolostnoy mhuka vane elongated, flattened muviri downwards, kureva. E. It ane sandarara kana substantially sandara. Uyewo, inguva yavo yokutanga pane bilateral symmetry mu ontogeny vakaisa matatu utachiona akaturikidzana - ecto, meso uye endoderm - izvo nhengo dzomukati vari kuumbwa mune ramangwana. Type Flatworms uyewo unoratidza kuvapo ganda-tsandanyama homwe ndiro uwandu hwezvinhu zvose zvabatanidzwa. epithelium uye kuraswa pasi tsandanyama fibers. Izvi zvinobvumira kuti "honye-se" kufamba.

The zvomudumbu Hurongwa iri akasununguka muchimiro chinyakare marongerwo uye rine foregut, kana pharynx, midgut, iyo inoguma tinongoita. In helminths ino nhengo hurongwa ipfupi.

Tsinga flatworms anomirirwa aiwanzopiwa wokushanda chepfungwa ganglia uye tsinga hunde dzacho, izvo pairi uye zvakabatana nokuda annular mabhiriji. Zvakasimba dzakabudirira dziri mbiri longitudinal abdominal hunde.

Kweropa uye kufema nehurongwa usipo. Fema vamiririri veboka ciliated epithelium, izvo akafukidza muviri wavo kubva kunze.

Excretory nhengo - protonephridia. Zvinosanganisira munhu tubular ino, izvo kuguma stellate masero pamwe cilia. Excretion pamusoro metabolic tsvina munzvimbo kwezvakatipoteredza kunoitika kuburikidza chaiwo excretory mawindo.

Dzokubereka nadzo hermaphrodite uye zvinokonzerwa kwegadziriro ducts, izvo zvakafanira kuti zvibviswe pabonde zvigadzirwa, uye copulatory nhengo kuti pezviri muchangosangana.

Saka, rudzi sandara Makonye - izvi kumboda parasitic siyana (helminths), vakakwanisa kuchinja uye kuchinja mararamiro avo.
