Ulwakhiwo yenamvuna: zangaphandle nangaphakathi

Ubume yenamvuna, nto leyo emele uhlobo arthropods ezinxulumene bume yakhe. Oku mmi obabuthandwa amatsha into ephefumlayo usebenzisa iigilizi. Kweli phepha, i yenamvuna ziya kuqwalaselwa. Isakhiwo, imifanekiso, indawo kunye neempawu ubomi thaca ingqalelo yakho ngezantsi.

Iimpawu uphawu kwezilwanyana

Njengazo zonke arthropods, isakhiwo yenamvuna (mfanekiso ungezantsi uyakubonisa oko) limelwe nomzimba abamnkela omzimba. Intloko, Isifuba nesisu. ziqwempu umzimba zidityaniswe imilenze, ezibandakanya amacandelo ngamnye. Bona bayakwazi ukwenza iintshukumo ngendlela entsonkothileyo. imilenze ezigoba ngokuqhelekileyo incamathele nencum seziqingatha zomzimba. isakhiwo yenamvuna yangaphandle iyangqinelana iimpawu uphawu ngokupheleleyo arthropods.

yokuhlala

Yenamvuna inokufumaneka ngamanzi ahlaziyekileyo. Ngaphezu koko, ubukho babo kubhekwe njengento sisalathisi ukhuseleko zemvelo. Ngapha koko, ezi zilwanyana bakhetha amachibi ngamanzi acocekileyo kunye nomxholo eliphezulu oxygen. Ubume yenamvuna linoxanduva bayakwazi ukukhasa ngoncedo enemilenze ehamba, okanye qubha. Emini ukuba kwimikhukhu zendalo. Night njengezinambuzane ngaphandle imingxuma labo phantsi kwamatye kunye logs. Ngeli xesha bafuna ukutya. Kulo mba, yenamvuna azikho choosy. Bona jikelele are izidla. Ziimpethu, Qhotsa intlanzi, tadpoles, izilwanyana, ulele - kuya kufuneka ukuba uxhamle yenamvuna umlambo. Abayi eya umcimbi efile organic. Ukuba ugqiba ukuba isilwanyana akwariyam yakho ekhaya, ifanele ukutya nje ukutya ezikhethekileyo, kodwa inyama, imifuno kunye nesonka. Noko ke, ngelo xesha agcine nokucoceka kwamanzi kuya kuba nzima kakhulu.

Ulwakhiwo lwangaphandle yenamvuna

imihlaza umzimba iquka iinxalenye ezimbini. It cephalothorax nesisu. Inxalenye ephambili wambu ebizwa ngokuba yi-iqokobhe. A esiswini iqulathe amacandelo ebantwini zilungiswe kwi kwiipleyiti ezincinane ngaphezulu. On cephalothorax nayo iipere ezimbini zeepali, mouthparts kunye izibini ezintlanu imilenze behamba. Ngamnye kubo lenza imisebenzi ethile. Ngokomzekelo, isibini sokuqala iziphelo neenzipho enamandla ukuba bakhonze ukubamba ukutya, nihlinza ndawaphula, kunye nokhuselo ezintshabeni.

izibini ezintandathu imilenze ziqhotyoshelwe esiswini. Laba lokugqibela imilenze kwandiswa kwaye kunye iifomu ipleyiti ezimpundu nesisila. Imbonakalo kufana fan. Nge yenamvuna ezimpundu ngokukhawuleza ukuqubha emva ekupheleni kuqala. Bebonke ke ka 19 imilenze.

izigqubuthelo zomzimba

Iimpawu Isakhiwo yenamvuna ngokuyintloko ezimiselwe kwiphepha lalo. Njengabo bonke arthropods, oko bubonakaliswe Ulobuza, enza exoskeleton enamandla. Inika ezongezelelweyo carbonate lukhuni calcium, nto leyo buzane.

Ekubeni Ulobuza lingenako olule, ukukhula yenamvuna ephelekwa molts ngamaxesha. Le ixesha ebalulekileyo kubomi ezi abahlala yamanzi. Kwiintsuku ezimbalwa ngaphambi kokuba eli itempile abe ziyagungqa, yima zokuxheshisela, kwaye lonke ixesha elichithwa zikhangela yokuzimela. Ngeentshukumo enamandla nasemilenzeni umzimba ukuba balahle iphepha omdala ukusuka apho zivela ngenxa lisikwe kwi cephalothorax kumda nesisu. Kwenye indawo ekhuselekileyo imihlaza na ukuya kwiintsuku ezilishumi, de Ulobuza esitsha iqaqadekile.

Isakhiwo sangaphakathi yenamvuna

Ngexesha Uphuhliso osandul zonke arthropods wabeka umngxuma umzimba yesibini. Ke yena akabi kuqhubeka ngenxa yonke ubomi besilwanyana. Kwinkqubo yophuhliso ngamnye kwesi sakhiwo ibhuqiwe, ukuhlanganisa kunye yokutyiwa eziziiprayimari oxutywe ukwenza umgodi. Izikhewu phakathi imizimba azele umzimba amafutha kwezilwanyana. Kuyinto uhlobo izihlunu evakalala nokuqina, nto leyo elenza imisebenzi ebalulekileyo: yokugcina izondlo, ukuyilwa iiseli zegazi, ukhuseleko ngokuchasene umonakalo.

inkqubo Musculoskeletal

Ubume yenamvuna yahluke kakhulu ukusuka ubume izilwanyana kunye coelenterates. Ingakumbi, azinayo ulusu-kwimisipha sac. Phantsi kophahla olunamandla iinyanda zihlunu striated ukuba uyakwazi nciphisa ngokukhawuleza.

iinkqubo zomzimba

Isakhiwo lwangaphakathi yenamvuna azilungiswanga ezintsonkothileyo iinkqubo omzimba. Sokugaya - uhlobo ngalo, kunye nobukho wesibindi amathe amadlala ukuba cell enzayim ndoyidiliza izondlo. Iimveliso pathways zokugqibela zisuswe emzimbeni esebenzisa inkqubo excretory, ngaphandle tubules Malpighian.

Nokuphefumla yenamvuna ngenxa ukunkcenkceshela bume yakhe, lo iigilizi. kakhulu zinxulumene kwegazi. It is hhayi ivaliwe. imithambo yegazi uvule kuloo ndawo ibinomthwebeba emzimbeni, ugalelwe uhlobo wayo wamanzi hemolymph. Inika zothutho ioksijini, icarbon dioxide, izondlo, iimveliso yokucolwa.

Umsebenzi ibalulekileyo lo hemolymph kunye zokhuselo. Iqulethe iiseli ezikhethekileyo ukuba enze isindululo capture kwamagciwane pseudopodia amoeboid nezicola kubo. Ukuhambisa hemolymph komzimba inika isitya anquma eliguquguqukayo - intliziyo. Njengoko igazi oluxutywe ulwelo coelomic kwaye yahlulwe emithanjeni kunye lwemithambo, yenamvuna na isilwanyana zinegazi elibandayo. Oku kuthetha ukuba ubushushu bomzimba waso buyehla ukuya ukupholisa kokusingqongileyo.

Ekupheleni ekwindla yenamvuna aqale phinda. Oku izilwanyana dioecious kunye nophuhliso ngqo kunye kwezichumiso lwangaphandle. Iduna namasende amabini kunye yobudoda Umbobho, imazi - oviducts maqanda kunye nesithandwa sakhe. Emva kokukhulelwa, amaqanda abo kwi esiswini imilenze ababhinqileyo. Ngoko ibonisa wemvelo koomama, efun malunga nenzala elizayo. Ngasekupheleni kwentwasahlobo okanye ekuqaleni kwehlobo kubo ngoyaba ezi oononkala abaselula ukuba umfuziselo of abadala.

Kwanele kunzima ukufumana kunye luvo. It iqulathe amacandelo ngokwahlukeneyo: ngaphambili, phakathi nangesemva. Okokuqala alungise umsebenzi amehlo, inika iimpendulo zokuziphatha nobunzima kakhulu kwezi zilwanyana, kwaye Mthovu lokuphumla innervate. Ingqondo enxulumene anatomically kunye intambo luvo ventral, ukusuka apho umzimba luvo ngamnye yandisa.

Ixabiso endalo kunye nobomi babantu

Ezisencinci yenamvuna ifomu kwizidalwa yamanzi ahlaziyekileyo - zinendima ebalulekile lokuthengwa kwempahla. Ukusebenzisa ukutya izilwanyana kwabafileyo, bona bume ecocekileyo. Kutshanje, ngenxa nefuthe elibi kakhulu inani labantu yenamvuna yabantu iye yehla kakhulu. I dirty yenamvuna amanzi inzala ekugqibeleni elindele ukufa. Oku kuyenzeka kwakhona ngenxa ixabiso yorhwebo obalulekileyo mmeli arthropods. Ngapha koko, inyama yenamvuna yimveliso ezixabisekileyo ukutya, kwaye kwezinye iindawo nokuba sidlo. Kuyinto zizityebi iiprothini, iivithamini kunye izinto, azafunyanelwa ndawo. Yenamvuna na ummeli iklasi inkulu ohlala emanzini ahlaziyekileyo. Ukugcina olu hlobo hlobo, kude kube phakathi ku-ehlotyeni zokuloba wavalwa ngokomthetho.

Ubume lomlambo kubangelwe ikakhulu umhlaza akuyo kwaye igqiba nokubaluleka kwayo kwindalo kunye nobomi babantu.
