Uyini indlala wokugaya ukudla e imbaza? Izici isakhiwo molluscs

Isihloko sethu lunikezelwe izilwane zasendle ezimangalisayo - mollusk. Ngenxa izici of isakhiwo, baye balufunda kokubili imvelo aqueous nezwe emoyeni. La magciwane benezingane eziningi izakhiwo ukuthi ahlukile kubo. Uyini indlala wokugaya ukudla e imbaza futhi isiphuku ingaphakathi, iflothi, castle, uphondo? Ake sibheke ndawonye.

Izici isakhiwo molluscs

Igama lobu bunye ehlelekile lihunyushwa lisuselwa Latin lisho ukuthi "myagenkie". Ngempela izimbaza (isithombe ngezansi sikhombisa omunye abameleli uhlobo) kukhona ezingenamgogodla. umzimba wabo ezithambile unsegmented ngokuvamile ivikelwe usinki inezingxenye ezintathu: ikhanda, esifubeni kanye nasemilenzeni. Ngamunye wabo ithwala eziningi imizimba.

Ekhanda lakhe, i-pair of tentacles benzela isitho ethintekayo. Foot kuyinto ohlangothini ventral yomzimba, ukuvumela ukuhamba molluscs. Wendlovu izilwane bevela kuzo zonke izinhlangothi lizungezwe amashidi nesibaya, othiwa nesiphuku. Ngenxa yalokho kwakheka umgodi is phakathi lesi sakhiwo futhi umzimba. Kuyo kukhona izitho zokuphefumula, Amapayipi we wokugaya ukudla, excretory futhi izinhlelo zokuzala.

Basics of ngezigaba

Sicela uqaphele ukuthi izimbaza, izithombe zazo okwethulwa kulesi sihloko makhulu izici ezahlukene zangaphandle. Kuye lezi zici, kukhona izigaba ezintathu: Bryuho- futhi Cephalopods, Bivalve. Abamele iqembu lokuqala aba yingcweti emisebenzini hhayi kuphela machibi, kodwa futhi ezihlukahlukene iziza: inhlabathi noma ihlathi phansi. Ngesikhathi gastropods achazwayo kahle zonke izingxenye zomzimba. Isiqu iningi labo zitholakala ngaphakathi igobolondo helically uyisontile.

cephalopods umzimba siqukethe imilenze esifubeni nasemlenzeni modified zibe ihambe. Isici nobuntu lesi sigaba ikhono jet ngamandla. Lena sibonga kungenzeka ukwakheka ekhethekile ijabulise - uphondo. Kuyingxenye sokulungisa umlenze.

Bivalves ukuphila kuphela imizimba amanzi. Abanaso inhloko, futhi ngenxa yalokho ophucwa izitho: ihambe, nomphimbo, ulimi, kanye iflothi, nezindlala salivary. igobolondo yabo siqukethe amaphiko amabili, okuyinto ezinhlotsheni eziningi zezinto eziphilayo kufanele projection futhi kude. iqoqo yabo ibizwa ngokuthi le nqaba.

Isakhiwo isimiso sokugaya ukudla bungene

Zonke izimbaza kukhona ngokusebenzisa isimiso sokugaya ukudla bungene yohlobo. Ngo cephalopods Bryuho- futhi iqala kuvulwa umlomo. On walo ne pharynx elise emihlathini Horny. Ngosizo lwabo, ukudla izimbaza esusa kusukela evele ahlukahlukene. I ingquza, okuyinto iphela uhlelo, ivula phakathi komgodi nesiphuku.

The main indlala wokugaya ukudla e imbaza - esibindini. Limelela yayifanekisela nomxhantela we midgut. Izinhlobo eziningi abe ndlala salivary. Cishe bonke Cephalopods ezishisa kakhulu zikhipha izinhlayiyana izidakamizwa ezinesihlungu ngawo thwebula inyamazane futhi zibabulale.

Uyini indlala wokugaya ukudla e imbaza

Le ngxenye isimiso sokugaya ukudla bungene ubizwa nangokuthi isibindi-amanyikwe noma yensimbi gepatopankreaticheskaya. Ngokusebenzisa Amapayipi abazinikezele iqhubeka ne-amathumbu. indlala-ukugaya e imbaza ehilelekile ukugaya kanye ukumuncwa izinto eziningi eziphilayo. Iyindawo esitolo amafutha kanye carbohydrate, futhi uyazifeza phagocytosis.

Uyini indlala wokugaya ukudla e imbaza, okungokwendlela ekilasini cephalopods? Ukuze amalungu aleli qembu zinezikhathi isakhiwo ezikhethekile. Yibo bodwa kwesibindi, amanyikwe kanye salivary nezindlala.

Izinhlobo zokudla: Bivalves futhi Cephalopods

Izici isakhiwo wokugaya ukudla of shellfish ekilasini ngalinye kanye nohlobo ukunikezela ziyahlukahluka. Ngokwesibonelo, bivalve ejwayelekile kukhona isihlungi esebenza ngogesi. Ukuze wenze lokhu, basebenzisa isakhiwo okhethekileyo, obizwa ngokuthi namapayipi amunca amanzi. Ziyakwazi ezimbili zama. Ongena ngesango i itheku elizenzekelayo amanzi izinhlayiya organic okwesikhashana. I ingaphakathi isiphuku it is elicwengekileyo. Ngosizo cilia ukudla engena umlomo. Kudlulwa pheshana, lingena isicupho ibhodlela.

cephalopods Iningi - eziyingozi. tentacles zabo zitholakala amaswidi ezisiza catch bese ubamba inyamazane. Zidla on ezinamagobolondo, inhlanzi kanye nezinye ezinamagobolondo. I cephalopods temlomo kukhona grater kanye nemihlathi Horny. Zinamandla ukuze bayakwazi akuqede ngisho amagobolondo of izinkalankala. Ukuze ukuze ahehe inyamazane, lezi mollusk babe izitho olukhethekile luminescence. Futhi ukuze kuvikelwe ezitheni basebenzisa inki indlala. Lapho emanzini kwakheka imfihlo endaweni emnyama ngaphansi isembozo lapho isilwane efihla.

Izici Amandla molluscs: Gastropods ekilasini

Lezi mollusk ku amaningi izimo, kukhona herbivorous. Lapho uhamba bona esusa ulwelwe usebenzisa grater nemihlathi Horny. Uyini indlala wokugaya ukudla e imbaza kuleli kilasi, okuyizinto izilwane eziphila ngezinye? Ezinye zalezi zinhlobo ukubunjwa ngamathe kuhlanganisa sulfuric acid. Umzimba womuntu ungakwazi Ukuqedwa amagobolondo zezisulu noma ushevu izitha. Okunjalo gastropods okuzingela grater esetshenziswa kuphela ukubamba isilwane abasifunayo.

Uma emlonyeni, izinhlayiyana zokudla unamathele ngamathe viscous. cilia eziningi, okuyinto zitholakala emphinjeni, wathumela lo yinhlama esiswini sami. On ithiphu yayo ekugcineni isakhiwo ekhethekile, okuthiwa prostyle. Lakhiwa izinhlayiya sedimentary. Prostyle Unjengomahluleli esondweni, uhlukanisa izinhlayiyana zokudla kusuka ngamathe.

Ngokumangalisayo, kukhona ukudla solemy shellfish. uhlelo yabo wokugaya ukudla kuyehla ngokuphelele. Ososayensi basikisela ukuthi nokwenziwa ukudla basebenzisa amagciwane chemosynthetic.

Ngakho, clams kukhona ezingenamgogodla ukuthi ube nomzimba othambile unsegmented. Sinenkosi ngokusebenzisa isimiso sokugaya ukudla bungene yohlobo, kanye nezindlala ezikhethekile: salivary, amanyikwe kanye isibindi. Ngokwe-indlela shellfish ukunikezela angaqoqwa ngamaqembu amathathu ezibanzi: isihlungi esebenza ngogesi, herbivorous nasezilwaneni eziyingozi.
