Yintoni na le ingaba zokwetyisa lembaza? Iimpawu ubume be-molluscs

Inqaku lethu lunikezelwa zasendle emangalisayo - mbambela. Ngenxa awohluke yesakhiwo, baye kakuhle zombini bume zolwelo nomhlaba-moya. Ezi izinto eziliqela izakhiwo ezikhethekileyo kubo. Yintoni na le ingaba yokwetyisa kwi lembaza neyokwaleka kwisisu, edadayo, nqaba, nengenisa? Makhe sijonge kunye.

Iimpawu ubume be-molluscs

Igama le manyano indlela Liguqulwe lithatyathwa Latin lithetha "myagenkie". Eneneni saselwandle esineqokobhe (photo ngezantsi ibonisa enye abameli uhlobo) are ezingenamqolo. umzimba yabo soft unsegmented kudla ukhuselwe kumgxobhozo kwaye iqulathe ezintathu: entloko, esifubeni nasemilenzeni. Ngamnye kubo ithwala eziliqela imizimba.

Phezu kwentloko yakhe, iperi Mpondwana benzela ilungu oyivileyo. Unyawo phezu kwicala ventral umzimba, evumela ukuhamba molluscs. Buti izilwanyana ezivela macala onke ejikelezwe yi amaxwebhu esibayeni, ekuthiwa ingubo. Ngenxa yoko umngxuma amiliswe phakathi kwesi sakhiwo kunye nomzimba. Kulo amalungu nokuphefumla, imibhobho wokugaya ukudla, excretory kunye neenkqubo zokuzala.

Basics yokuhlelwa

Nceda uqaphele ukuba isilwanyana, iifoto ezo thaca kweli nqaku makhulu iinkalo ezahlukeneyo lwangaphandle. Kuxhomekeka ngezi mpawu, kukho iiklasi ezintathu: Bryuho- kunye izilwanyana, namaqokobhe. Abameli iqela lokuqala Sendisicwaba nje imizimba yamanzi, kodwa iindidi iziza: umhlaba okanye ihlathi. Xa neegastropods ziphuhliswa kakuhle onke amalungu omzimba. Boko of uninzi kubo ibekwe ngaphakathi kwiqokobhe helically ejijekileyo.

izilwanyana umzimba iqulathe imilenze umntla kunye nomlenze basis zibe nemisipha. Eyona uphawu kule klasi kukukwazi jet basafunda. Oku ngenxa kunokwenzeka ukuba kusekwe ekhethekileyo tubular - ifanele. Oku kuyinxalenye basis of the umlenze.

Bivalves bahlala kuphela kumaqumrhu emanzini. Abanalo intloko, yaye ngenxa yoko, ndayihluthwa amalungu: nemisipha, umqala, ulwimi, kunye edadayo, kwamadlala amathe. iqokobhe kwabo iqulathe amaphiko amabini, nto leyo kwiintlobo ezininzi babe uqikelelo kunye emathambekeni. ukuqokelelwa kwazo ibizwa nqaba.

Ubume nkqubo wokugaya

Zonke saselwandle esineqokobhe ngokusebenzisa inkqubo yokucola lohlobo. Xa izilwanyana Bryuho- kwaye iqala lokuvula umlomo. On emdeni wayo pharynx ibekwe imihlathi horny. Ngoncedo lwabo, ukutya saselwandle esineqokobhe kokuphalwa ezivela kwiindawo ezahlukeneyo. Ingquza, esiphela nenkqubo, ivula kuloo ndawo ibinomthwebeba yokwaleka.

Le ingaba ephambili zokwetyisa lembaza - esibindini. Umele izalelwe le midgut. iintlobo ezininzi ingaba amathe. Phantse zonke izilwanyana kukhutshwe into enetyhefu ngayo amanzi amaxhoba nibabulale.

Yintoni na le ingaba zokwetyisa lembaza

Le yinxalenye yenkqubo kokudla nako ngokuba isibindi-nepancreas okanye intsimbi gepatopankreaticheskaya. Ngokusebenzisa imibhobho akayisungula iqhubeka kunxulumana amathumbu. ndlala zokwetyisa lembaza inxaxheba yokwetyiswa nokufunxwa kwezinto eziphilayo. Yindawo emafutheni ukugcina kunye carbohydrate, kananjalo uphumeza phagocytosis.

Yintoni na le ingaba zokwetyisa udaka, ziphantsi udidi izilwanyana? Kuba amalungu eli qela luphawulwa isakhiwo ezizodwa. Bona bodwa isibindi, injeke kunye amathe namadlala.

Iintlobo zokutya: Bivalves kunye izilwanyana

Iimpawu ze isakhiwo ometyiso kweembaza yeklasi nganye kunye nohlobo supply ziyahluka. Umzekelo, namaqokobhe eqhelekileyo mdla lokucoca ulwelo. Ukuze benze oku, basebenzisa isakhiwo okhethekileyo, ngokuba amanzi. Bona kweentlobo ezimbini. Ongena nge owongozelelweyo elizenzekelayo amanzi kunye organic amasuntswana emsebenzini. Faka i ingubo kokuba yahluzwa. Ngoncedo lwe ukutya isiliya ongena lokuvula umlomo. Ehambahamba iphecana, ingena umgibe ibhotile.

izilwanyana ezininzi - ngamarhamncwa. Mpondwana zawo zibekwe iilekese ukuba ukunceda ukubamba ixhoba. Badla intlanzi, intlanzi kunye nezinye saselwandle esineqokobhe. Ezi izilwanyana ngomlomo ezi grater bemihlathi horny. Bona anamandla kakhulu ukuba bakwazi Ekutyunyuzweni nkqu kweqokobhe of oononkala. Ukuze ukutsala ixhoba, ezi izilwanyana kufuneka amalungu ezizodwa chweba. Kwaye ukuze asikhusele ezintshabeni ukuba usebenzise i-inki ndlala. Xa emanzini oko kwasekwa imfihlelo ibala amnyama phantsi kwekhwapha apho isilwanyana kufihla.

Amanqaku molluscs Power: iklasi neegastropods

Ezi mbambela, inani elikhulu amatyala, ezi herbivorous. Xa uhamba ukuba bawuphose umhlaba ulwelwe usebenzisa grater kunye nemihlathi horny. Yintoni na le ingaba zokwetyisa lembaza kule klasi, ezo abahlaseli? Ezinye zezi ntlobo kuhlanganiselo amathe iquka sulphuric acid. Kuyinto olukwazi dutywa kweqokobhe lwamaxhoba okanye iintshaba ityhefu. Ezo neegastropods ezingabahlaseli grater kuphela ukubamba ixhoba.

Kanye emlonyeni, amasuntswana ukutya babambelele ngamathe viscous. isiliya ezininzi, nto leyo ibekwe emqaleni, wathumela lo ebeleni isisu sam. On ekupheleni kwayo tip isakhiwo ekhethekileyo, leyo kuthiwa prostyle. It ukhandwa amasuntswana ludaka. Prostyle kukwasebenza emasondweni, bazahlule amasuntswana zokutya namathe.

Akumangalisi, kukho ukutya solemy saselwandle esineqokobhe. inkqubo yabo yokwetyisa yehliswe ngokupheleleyo. Izazinzulu lubonisa ukuba nokwenziwa ukutya zisebenzisa iintsholongwane chemosynthetic.

Ngoko ke, squid ke ezingenamqolo ukuba abe umzimba ethambileyo unsegmented. Baye ngokusebenzisa inkqubo yokucola yohlobo, kwakunye amadlala ezizodwa: amathe, injeke nesibindi. Ngokutsho indlela yonikezelo saselwandle esineqokobhe iziinxalenye amaqela amathathu ezibanzi: zeBRT filter, herbivorous eziyingozi.
