Excretory nā loko ma mollusks. Ka 'ole o ka pūpū

He nui ke ano o na holoholona. Keia a me flatworms, a me coelenterates, a me annelids, a me arthropods a me echinoderms a me chordates. Ka 'epekema e epa me ka hoʻopaʻa' ana o ia ua kapaia kālaimeaola. Ka pūpū - Ua hoʻi kekahi o nā ʻano o nā holoholona. Ka mea, e e kūkākūkā i loko o kēia 'atikala. Aia Ua hoi he kūikawā lala o ka kālaimeaola e haʻawina o ka holoholona pae. malacology kapa iho la ia. A 'epekema e epa me ke ao o ka mollusc pūpū, - conchology.

A mau ano o ka pūpū

Me ka Poeikohoia o kēia 'ano ua i kapaia spineless. Ka mea, i loa like. Ka helu o? Ueo - ma kahi o 200 tausani.

Kēia pūʻulu o multicellular holoholona i māheleʻia i loko o ewalu papa:

• Bivalve.
• Kapa kila.
• Solenogastres.
• Caudofoveata.
• Monoplacophora.
• Gastropods.
• Niho a iwi.
• Cephalopods.

Ke kino o kēia mau holoholona ua hoonohonoho ma luna o kekahi, a me ka ia rula. Next e e kūkākūkā i oi au mamuli ano ka pūpū.

nā loko, a hui nenoai

Ka pūpū, like me na mea he nui multicellular holoholona, i kūkuluʻia no nāʻano likeʻole o nā fabrics, a he hapa o na Aupuni. Ka hope, i ka huli, kuahene hui, nenoai.

Ka 'ole o ka pūpū ka loaʻa o ka kēia nenoai:

• circulatory;
• ko mākou hopohopo'ōnaehana a me ka pono nā loko;
• digestive;
• excretory;
• hanu;
• anal;
• kino veils.

E ka lawe ia i ka mea.

circulatory kahua

I mollusks ia i wehe i type. Ua nā mea kino:

• naau;
• moku.

Heart molluscs ua haku o ka elua a ekolu keʻena. 'O kēia kekahi ventricle a me kekahi paha mau atria.

He nui spineless koko, he he hana bluish waihoʻoluʻu. Kēia 'ia nā pōpō häÿawi i kona naehana pigment hemocyanin, ma ka Nine Inch haku mele' ana o i ka loaʻa o ke keleawe. Kēia waiwai i ka ia hana me ia o ka hemoglobin.

Koko circulates ma molluscs like penei: mai ka ipu koko ka mea, ua nininiʻia i loko o ka hakahaka ma waena o na kino - lacunae a me sinuses. A laila, hou ka mea, ua ohi ia i ka moku a me ka lako i ka halo o mua a me akemāmā.

ko mākou hopohopo kahua

I mollusks ia ke hele mai i loko o nāʻano likeʻole: i ka hulili, a hoopuehu aku i-wahi type.

First kūkulu like penei: loaʻa peripharyngeal ke komo lima, mai a hohola akuʻehā barela. Elua o ia innervate i ka wāwae, a me nā 'ē aʻeʻelua - ka loko.

ʻO ko mākou hopohopo nenoaiu o ka hoopuehu ana-wahiʻano mea oi huikau. Ua he a mau hui o neural wahi i puhi ai. Elua abdominal kuleana no ka innervation o ka mea na nā loko, a me nā hehi wāwae - wāwae. He mau hui o nā aʻalolo wahi i puhi ai i keia manawa, aka wahi - ganglia. Ka mea, e IeAUPIIe, IAa IO eono hui: buccal, cerebral, pleural, hehi wāwae, parietal a me visceral. Ka mua innervate ka pharynx, ka lua - na tentacles a me ka maka, i ke kolu - i ka aahu, a me ka hā - wāwae, i ka lima o ka - ka naehana'ōnaehana, ka ono - i na nā loko 'ē aʻe.

makaukau no

Aia i ka pūpū mau kino, hiki ia lakou e loaa ka ike e pili ana i ke kaiapuni.

• tentacles;
• mau maka;
• statocysts;
• Osphradium;
• sensory keena.

Mau maka a me tentacles i aia ma luna o ke poʻo o ka holoholona. Osphradium kahi kokoke i ke kumu o ka halo o mua, Kēia Nine Inch hoohalike nā loko. Statocysts - he koena nā loko. Ka mea, i ka wāwae. Sensory aeee i kuleana no ke ano o ka nano. Ka mea, i aia ma ke kihi o ka aahu, ke poo a me ka uha mua.

alimentary kahua

Ka 'ole o ka clam eaaaony no ka mea, penei nā loko o ka'āpana.

• puu;
• esophagus;
• 'ōpū;
• midgut;
• hindgut.

Nō hoʻi, ke akepaʻa mea i loaʻa. Ma cephalopods , he mea no hoi i ka pancreas.

Ka pahee-kino puʻipuʻi kaniai he mea he kūikawā kino no ka wiliʻai - radula. Ua ua uhiia me ka niho, mai chitin, a ua hōʻano hou 'ia e like me ka wili ana o ka wa kahiko.

Excretory nā loko ma molluscs

Kēia'ōnaehana ninoieo o nā puʻupaʻa. Ka mea, i kapaʻia metanephridia. Excretory nā loko ma mollusks like me ka poe o na ilo. Akā, ka mea i hoonohonoho hou huikau.

Excretory nā loko ma mollusks hou me ka lākou o Kahualoa Kokohi ferrous paipu. Metanephridia kekahiʻaoʻao wehe i loko o ka coelomic eke kala, a me ka mea 'ē aʻe - mai.

Excretory nā loko mollusks i e noho i loko o kekahi mea. No ka laʻana, kekahi cephalopods i wale kekahi metanephridia aia ma kaʻaoʻao hema. I monoplacophora Ua malama like ka nui me 10-12 hui, e auaaeaiea.

I metanephridia ka pūpū loaa neoneo huahana. Ka mea, i na poe e popo palaoa o uricʻakika. I holoiʻia mai ka kino o ka holoholona ka mea, i kēlā mea kēia mau i ekolu pule.

Kekahi hapa o ka excretory'ōnaehana i loko o molluscs i ke kapa i ka atria, i kuleana no nā kānana i ke koko.

naehana kahua

Kekahi mau pūpū ka mea, ua poe ma na kino likeʻole. Ke'ī mai, i ka hapanui o ka pahee-kino puʻipuʻi makana halo o mua, Ka mea, i kekahi kapa ctenidium. Ua hui kaulua pono feathery kino. Ka mea, i ke aupuni 'o ke kapa lua. Ma mollusks e noho ana ma ka aina, kahi o ka halo o mua, he mea malamalama. He He Hoʻololi 'aahu lua. Kona mau pā i komo iloko ma na moku koko.

Ua mea i nui ka wahi i loko o ke kinoea kūkaʻi i ka pūpū ili hanu.

reproductive kahua

Ua hiki ke hoonohonoho ia ma naʻano likeʻole, e like me ka mea mau i waena o nā clams i hermaphrodites a me dioecious? Ueo. Ma ka hihia wā fertilization hermaphroditism kēlā me kēia kanaka a pau e like me nā he kane a he wahine.

A nānā mākou i nā mea a pau o ka hui, nenoai o ka pūpū.

kino veils ka pūpū

Ke 'ole o kēia hehee ai loli aʻe i loko o ka poeikohoia, o kekahi papa.

E ka nānā i nā koho likeʻole o ka integument, a hiki i ka pūpū, holoholona examples e pili ana i ka kekahi papa.

Pela, ma solenogastres a caudofoveata poi makana i ka aahu e uhi i ke kino holoʻokoʻa, me ka cuticle iloko olaila o glycoproteins. A hooku iho spicules - he ano o ke kuikele, a iloko o ka Lime.

Ma bivalves, gastropods, cephalopods, a me ka niho a iwi monoplakfor kahi e cuticle. Akā, he mea he iwi, a he o ka hookahi papa a 'elua i loko o ka hihia o ka bivalve. Kekahi poe o ka papa gastropods keia hapa o ka wiwoʻole a lahilahi.

Hiʻona iwi 'ole

Ua hiki ke maheleia i ekolu papa. I ka pahale mawaho, waena a me ka loko.

Ka mawaho hapa o ka iwi ua mau kūkuluʻia mai ke aloha Nine Inch. Loa pinepine ia mea conchiolin. Ka mea wale nō koe a hiki i keia rula i ke noonoo Crysomallon squamiferum mollusk, mai ka papa mai o gastropods. Ua ua i mawaho iwi, ahu iho ua haku o ferrum sulfides.

Ka mawaena hapa o ka clam iwi ninoieo o columnar calcite.

Kūloko - he papa o ka calcite.

mākou iʻaneʻi i noʻonoʻo i au mamuli o ka 'ole o ka molluscs.

ka hopena

E hōʻuluʻulu pokole nānā i ka nui nā loko, a hui, nenoai o ka pahee-kino i loko o ka papaʻaina. I haawi examples o molluscs no i kekahi mau papa.

Ano, e noonoo i ka elele o nā papa likeʻole o Clams a me ka hiʻona o ko lākou 'ole.

Here mākou hookolokolo aku la ia i ka mall hiʻona o ka papa kuhikuhiE elele o ke 'ano o ka pūpū.
