Annelids: inkcazelo emfutshane yohlobo

ntshulube Annelid - iqela ngokufanelekileyo elikhulu eziphilayo ezingenamqolo. Ukongeza, ukuba nabameli ezininzi ziimpethu. Igcwele kakhulu amanzi kunye netyiwa, kananjalo emhlabeni. Ezinye inqwaba iintlobo ashinyeneyo bebeziqhelanisa kwindlela ezisentlabathini yobukho.

Chwetheza Annelida: iimpawu ngokubanzi

Amacala yale uluhlu qela ukusuka milimitha ezimbalwa ukuya kutsho kwiimitha ezintandathu. Lidla osemqoka Uphawu kuba phambi kwalo segmentation ephilayo - imizimba yabo sakhiwa ezininzi namakhonkco, echaza igama lohlobo. annulation yangaphandle elivumelana segmentation lwangaphakathi. Kungenxa yoko le nto xa umzimba wonzakele okanye ezonakeleyo annelid ulahlekelwa kuphela amacandelo embalwa, leyo kungekudala wachacha.

Ngaphandle umzimba ligutyungelwe Ulobuza, nto leyo kwakhona. Ukusuka okhulisayo ezifumaneka ngechitin - inomnye umsebenzi uphawu eli qela kwezilwanyana. Abanye abameli phezu ziqwempu kuba parapodium - kunokuba isintu imilenze, leyo kwezinye iimeko baxhotyiswa ezifumaneka ezibuthathaka okanye iigilizi.

Annelids: iimpawu noshowo izibilini

Kuba bale hlobo luphawulwa ebusweni umzimba uvuleke aphakamileyo - coelom. Le kwisisu izaliswe ulwelo othile, ngenxa yokuba inkxaso amanqanaba eziqhelekileyo yokusingqongileyo lwangaphakathi.

Kukho bag eluswini-dystrophy equka iibhola epithelium kunye izihlunu zib icici longitudinal band.

Inkqubo kokudla umnqamlezo bephela, umlomo iqala ize iphele nge empundwini. Annelids amacandelo amathathu emathunjini - ngaphambili, phakathi nangesemva. Olunye uhlobo benziwa kwamadlala amathe kwakudala.

Sakudala emzimbeni esikhumbeni. Ezi nketho kuphela iintlobo ezithile zezilwanyana zaselwandle apho parapodia iigilizi akhiwe. Njengoko inkqubo yokujikeleza kwegazi, oko ngokuqhelekileyo ivaliwe. It iqulathe aorta ventral kanye amaphiko, ezo mpahla thunzi ezihambelanayo. Heart kwezi zinto ziphilayo abanayo - ukuhamba kwegazi ukunika ukuhla aorta amaphiko. Igazi ziintshulube elakhiwa ezahlukeneyo zombala zifo.

I-luvo isekhona ilula. Ekugqibeleni phambi komzimba a ganglion luvo enkulu, nto leyo elenza imisebenzi ebuchotsheni. Isuka evela intambo luvo, enza ganglia encinane kwilungu ngalinye umzimba - zokwanda zemithambo-luvo. Iimvakalelo evezwa ngayo amehlo, imizimba iikhemikhali ubuntununtunu kunye mechanoreceptors, leyo zasasazwa kuwo umzimba kwale ntshulube.

Annelids: Iimpawu marekhodi kunye nophuhliso

Eziphilayo eli qela kunokuba zombini zingafaniyo hermaphrodites (anqabe kakhulu). Hi xikombiso, le lomsundulu iye inkqubo androgynous lokuzala, kodwa kuyimfuneko ukuba ukuchumisa kwabantu ababini. Oko kunokuthi kwenzeke zombini kwi okusingqongileyo kunye nokuqaliswa madlozi apha ngamajelo ababhinqileyo embilwini.

Okunye okunika umdla kukuba iimpethu abamnkela kunye segmentation ngokukhawuleza bathanda ngokutsha olukhawulezayo kakhulu. Ngenxa kule ezinye iintlobo ngumntu yokuzala maqanda. Uphuhliso eziphilayo ngqo, ngaphandle milo.

Kufuneka kuqatshelwe ukuba indima annelids kakhulu ezinzima. Umzekelo, a ezaziwayo-kakuhle lomsundulu unoxanduva nomoya zomhlaba. Eli qela libandakanya kunye rhorho, adla ngokusetyenziswa yesilungu. ixabiso Special iye hirudin yenziweyo uLeech, njengoko mlomo igazi kwaye esetyenziswa anti-thrombosis kunye nezinye izifo ezinobungozi.
