Inkqubo sokugaya izirhubuluzi: iimpawu zolwakhiwo kunye nokusebenza

Inkqubo sokugaya izirhubuluzi uneempawu zawo ezenza kube nzima ngakumbi kakhulu xa kuthelekiswa isakhiwo esifanayo kwi emanzini.

iimpawu ngokubanzi izirhubuluzi

Ezirhubuluzayo izilwanyana igama labo ngenxa yohlobo intshukumo kumphezulu womhlaba. nokuba Abanawo okanye imilenze ezimfutshane, ezo zicwangciswe elithe tyaba. Ngoko ke, ukuba kukho uhlobo "groveling" phezu komhlaba. Bonke bephela izilwanyana zinegazi elibandayo ukuba Sendisicwaba kunye namanzi, kunye zokuhlala ezisentlabathini. Kodwa ke uphuhliso imibungu, leyo siphahlwe kwiqokobhe ibakhusela iqanda lwenzeka ngokupheleleyo emhlabeni. umzimba isilwanyana esirhubuluzayo igutyungelwe isikali eyomileyo horny.

Ezona mpawu ziphambili ke imbonakalo isakhiwo lwangaphakathi yale esifubeni yokuphefumla kuphela yemiphunga, kwezichumiso lwangaphakathi kunye ezirhubuluzayo inkqubo excretory, bemelwe yi nezintso, esinyini kunye cloaca.

inkqubo yokucola: amasebe eziphambili

Inkqubo sokugaya izirhubuluzi imelwe phecana kunye namadlala ezizodwa. Ngokungafaniyo eziphila emhlabeni nasemanzini, phakathi kwezi zilwanyana kuba kwamadlala amathe ezibangela enzymes. Ezi zizinto zendalo zizinto ehlanganisa eziphilayo. Bahlomele lo mbandela eziphilayo ezimbaxa zibe ezilula. Kule fomu zona wendele ize ifakwe reserve. Ulwakhiwo ezirhubuluzayo inkqubo yokucola linophawu bubukho amazinyo undifferentiated kunye cecum. Ezi mpawu ziphambili zintsonkothe kuthelekiswa emanzini.

ezirhubuluzayo kokudla iqulethe umlomo, pharynx, kuvuleke iminxunya emxinwa, isisu kunye emathunjini. ngokwahlukeneyo lokugqibela lenziwa ngamasebe ezincinane nezinkulu, adlulele le cecum. Igcina sokugaya tube cloaca. Le yi ukuvulwa apho ume ngaphandle nje kuphela nepererevarennye ukutya okuseleyo, kodwa ke imveliso zeenkqubo excretory nenzala izirhubuluzi.

ndlala sokugaya

Inkqubo kokudla izirhubuluzi kakhulu inzima. Ekugayeni zombini ukutya izityalo kunye nezilwanyana ukuba badle, bekuya kuba nzima ngaphandle phambi yentsimbi. Kwakhona izinto amathe kunye nee-enzayim leyo ninamathele, ogalelwe kwaye ibhexesha nokudla ukutya, ezirhubuluzayo isibindi nepancreas. ilungu ngalinye lenza umsebenzi wayo. Kwesibindi likhipha inyongo, leyo disinfects acazulule amasuntswana ukutya. A injeke cell enzayim ukugaywa epheleleyo iiprothini, amafutha kunye carbohydrate.

Enzyme ezirhubuluzayo glands yokusila kukho izinto afana esebenzayo. Ngoko ke, bonke kakuhle kuyaziwa ukuba iinyoka musa ukuhlafuna ukutya kwabo, kunye nokuthimba ixhoba yonke yabo. Inkqubo ukwetyisa iqala esiswini kuphela. Maxa wambi kuba ixesha ukuya kwiiveki eziliqela.

features kama

Njengoko sele kukhankanyiwe, inkqubo excretory izirhubuluzi luphawulwa iimpawu ezithile iingxaki. Nangona yokuba zonke emazinyweni em- oropharyngeal ezifanayo nikhonze kuphela ukufaka ubambe ixhoba, spetsialirovannye apho. Umzekelo, iinyoka ezinobuhlungu. Abantu abaninzi bakholelwa ukuba bungabi ixhoba labo encediswa ulwimi. Kodwa ke akunjalo. Ezi kwisisu yomlomo izinyo enobuhlungu, apho kukho isiteshi into ityhefu. Yaye imihlathi ezidla ezifana iingwenya, ndiyinyothule kunako ukwenzeka, kuba amazinyo abo banamandla ngakumbi kwaye elibukhali. Umzekelo, yabe isilwanyana ngokufuthi "umsebenzi" kwemini ukuya amashumi ezininzi amaxesha ngonyaka ngamnye. Hi ndlela leyi, ngokungafaniyo emanzini, uninzi lwazo ulwimi lelona candelo lungabanjwa ukutya, umzimba krokodidov phantse ihlanganiswa esisekweni emlonyeni, ngenxa yoko kuyabonakala ukuba ayikho kwaphela.

sokugaya imisebenzi system izirhubuluzi

Sokugaya inkqubo ogcweleyo ezenzelwe yokwetyiswa nokufunxwa kwezondlo. Xa cleavage kwabo zabelwa isixa-mali esithile wamandla esetyenziswa yi eziphilayo kuzo zonke iinkqubo ebalulekileyo. Xa le cleavage kwenzeka ngokusebenzisa enqanda ezizodwa kwamadlala, kunye nentshukumo kwamasuntswana ukutya ukusuka kwisisu somlomo ukwenza udonga iphecana kwezihlunu cloaca.

Ngenxa yoko, inkqubo yokucola iye izirhubuluzi ezifana iimpawu zolwakhiwo ngokuqhelekileyo chordates, abanye bahlukile. Kucacile ukuba kuthelekiswa eziphila emhlabeni nasemanzini, kuba nzima ukufumana ngakumbi. Oku kubonakala ebusweni enzyme ukuba ekhutshwa ngamadlala ezizodwa, cecal kunye kumahluko emathunjini.
