Ziintshulube: inkcazelo emfutshane yohlobo

Ziiroundworms, okanye njengoko kubhekiselelwe kuwo nematodes, ukuba izinto eziphilayo kunye umzimba uvuleke zaseprayimari. Baya bahlala kwiindawo ezininzi ezahlukeneyo kwi planethi - yeelwandle, amanzi acocekileyo kunye nomhlaba. Ezinye Abameleli gazi - lukhona ngeendleko zezityalo nezilwanyana eziphilayo. Eyona edumileyo ikutyela oluntu kunye amile Trichinella.

Ziintshulube Uhlobo: iimpawu zezakhiwo. Igama yavele uthi isakhiwo abameli olu hlobo - in cross-kwicandelo zibe imilo ngeenxa zonke. yomzimba fusiform kwaye iingqameko ethe shinyi, uyakwazi ukubona ngokucacileyo intloko kwi ekupheleni ngaphambili. lohlukanisa uhlobo umzimba - abambiseneyo.

Ke ubungakanani ezi zinto ziphilayo, ziyashiyana kakhulu - ukusuka ezincane (microns 80), ukuya phantse ingxilimbela (ngaphezu kwama-8 yeemitha a nezinambuzane womnenga).

umzimba yabo ibandakanya kwisingxobo ulusu-imisipha wahlukile amalungu angaphakathi kwisisu lokuqala, okanye psevdotselem. Le ulusu legqunyiwe ngomaleko ngci encotsheni Ulobuza, apho iveliswa epithelium integument lwangaphandle.

Ziintshulube: isakhiwo kwinkqubo yokwetyisa. wokugaya ngokusebenzisa eli qela eziphilayo. imbobo Oral ilahlwe ekupheleni phambili lomzimba engqongwe imilebe inyama kwezihlunu. Oku kukhokelela pharynx dystrophy, esetyenziswa zokutya sokufunxa esebenzayo. Ukutya ke Asikokungena phakathi, uze kule hindgut. iimveliso pathways ukuba betekisi ngokusebenzisa empundu amabhinqa okanye amadoda cloaca.

Okubangel 'umdla kukuba ezinye izinto olwaye lwamfimfitha olu hlobo tube yokwetyisa kwaye uguqulwe engxoweni encinci imingxunya.

Ziintshulube: nokuphefumla kunye zinomgutyulo. inkqubo excretory ziintshulube amahle. Ezi ziquka i olunye-cell amadlala ezinkulu wesibeleko. Iimveliso pathways yande kulwelo kwisisu, emva koko imiphantsi ezimbini longitudinal osisi kunqwenela ngayo intsimbi lilahle ngaphandle. Intamo umntu ngentsimbi eyahlukileyo excretory lokuvula leyo kuvula kwamathumbu isabelo umzimba. Ezinye metabolites, ezifana ammonia, ukuba betekisi ngqo eludongeni umzimba.

Ke ukuba ukuphefumla, esixhotyiswe ngokukodwa esilungiselelwe amalungu akukho eziphilayo. Mpilo kwelifunekayo kwizihlunu emathunjini. Xa kunjalo, ukuba kufuneka uphile kweemeko oksijini yindlala, ziintshulube zinokudluliselwa luhlobo anaerobic of nokuphefumla.

Ziintshulube kunye nenkqubo yabo luvo. Inkqubo luvo kwezi zinto ziphilayo kunokuba likumgangatho ophantsi, ingakumbi kwiintlobo olwaye lwamfimfitha. Iziko engundoqo ukudibanisa thaca peripharyngeal luvo ganglia, ukusuka apho zemithi ezimbini luvo kumka.

Yona izivamvo, zibekiwe papillae, seta, nengxelo amphids drugiemi. oku Zonke - imizimba mechanical, imichiza, novakalelo ukukhanya. Kule hlobo lweentshulube izivamvo angaphantsi eseliphuhlile ngendlela free.

Ziintshulube: ukuzala. Abameli olu hlobo izilwanyana zizinto eziphilayo dioecious. Ngelo xesha apho yaye dimorphism ngokwesondo buqapheleke - isiphelo oyindoda angasemva uzimisele ukuya inxalenye ventral lomzimba.

esini Female zimelwe zamaqanda, isibeleko kunye oviducts. Inkunzi emasende, Vas efferens duct ejaculatory. Isidoda oyindoda ebiqaliswe kwi lobufazi ye-organ copulatory nemazi nge. Okubangel 'umdla kukuba, isidoda abe misila, abanalwazi ukuhamba kunye nemilo amoeboid.

Ezi ziintshulube ezahlukileyo moya? Eneneni, umahluko phakathi kweentlobo ezimbini zezilwanyana kakhulu azikaqapheleki. Okokuqala, kufanelekile ukuba sikhankanye malunga ukuma umzimba - a Flatworms cross-lecandelo unawo umzimba atshabalalisa. Omnye umahluko ebalulekileyo - oku ke umzimba uvuleke zaseprayimari, apho akabikho abameli flatworms. Ukongeza, i-nematode sele kukho-ngokusebenzisa inkqubo yokwetyisa. Kufuneka kuqatshelwe ukuba iimpethu caba - hermaphrodites.
