Annelids: he manawa pōkole ano o keʻano

Annelid ilo - 'ano nui pūʻulu o invertebrate meaola. Eia hou, ka mea,ʻo ka loa i hoʻonohonoho 'laʻelaʻe' ia o nā ilo. Ka mea, i loaʻa kuhikuhi ma ka hou a me ka paakai wai, a me kekahi i loko o ka lepo. Kekahi Tropical? Ueo leeches i hakuloli he ano honua kahi pololei o ke ola i.

E kikokiko Annelida: mau ano

Ana o keia pae huahelu, mai kekahi mau millimeters mai i eono mau mika. Muli o kona kulana ano hiʻona o ke alo o keia meaola segmentation - kā lākou mau kino ua haku o ka ai iiiaanoaa o nā apo, a wehewehe i ka inoa o keʻano. Mawaho annulation hoʻopili like i ka mea maloko segmentation. I mea no ke aha la ka wā i ke kino ua poino paha poino annelid haalele wale i kekahi mau Hoʻohana, i koke loaa hou ai.

Mawaho o ua uhiia i ke kino me ka cuticle, i ua ole Ho'ā hou. Mai ka mea, e ulu chitin hulu - kekahi ano hiʻona o keia pae ana o na holoholona. Kekahi mau elele ma ka Hoʻohana hiki e parapodium -ʻano primitive mau lala, a ma kekahi mau hihia i hoʻolako pono me ka 'ikepili koʻikoʻi hulu paha halo o mua,

Annelids: mall hiʻona o ka mea na nā loko

No ka 'elele o kēia' ano ua wehewehe aku ma ke alo o ka haumāna kino lua - coelom. Ua piha kēia lua me ka kekahi loli, i ke aloha i ua kākoʻo pae maʻamau o ka maloko kaiapuni.

Aia ka he ili-muscular eke a he o nā waihoʻoluʻu epithelium a me ka Muscle Hoʻohui 'i loko o ke komo lima, a lonikū koa.

Ke digestive'ōnaehana mea he keʻa-ana, waha hoʻomaka a me ka welau a me ka anus. Annelids i ekolu māhele o ka naʻau liʻiliʻi - mua, waena a me ka hope. Ma kekahi? Ueo hana primitive salivary glands.

Ha i ke kino ma ka ili. Na, koe wale nō kekahi meaola nā holoholona laha 'ma i ke parapodia ke aupuni' halo o mua. Like no ka mea circulatory'ōnaehana, ka mea, ua ana paa. Ua ninoieo o ventral a me ka dorsal aorta, i mea interconnected annular moku. Heart i loko o kēia mau meaola e ole i - o ka neʻeʻana o ke koko i kekahi ka ho'ēmiʻana i loko o ka dorsal aorta. Koko roundworms e hoʻohui pū i keʻano o naehana pigments.

ʻO ko mākou hopohopo'ōnaehana Ua nō he mea. Ma ka mua hope o ke kino o ka nui nā aʻalolo ganglion, i hanaʻia oihana o ka lolo. Ua haalele mai ke aʻalolo kaula, a 'ano apau loa he uuku ganglia i loko o kēlā me kēia Hoʻohana o ke kino - ka hoʻomāhuahua o neurons. Makaukau no ka mea, hooku iho la ia ma na maka, Nine Inch pā lonoaʻili kino a me mechanoreceptors, a i haawi ma ke kino o ka ilo.

Annelids: nā hiʻona nā'ōlelo a me ka ulu ana

Meaola o keia pae hiki e nā heterosexual a me hermaphrodites (nui rarer). No ka laʻana, ka mea earthworm he androgynous reproductive'ōnaehana, akā, ia mea e pono ai ka fertilization o mau kanaka. Ua hiki ke ana i na i loko o ka papa, a ma ka hoike ana o sperm i loko o ka wahine loko kaha.

Kekahi hana hoihoi oiaio mea i ka Hoʻohana ilo me ka haʻi segmentation i ka welelau o ke kokololio a me ka mālama nui e noho. Manawa a hiki i keia no kekahi? Ueo typical o asexual nā'ōlelo. ? Ac? O meaola pono, me ka metamorphosis.

It E e hoʻomaopopo i ke kūlana o ka annelids he koʻikoʻi. No ka laʻana, he luawai-ike earthworm mea kuleana no ka aeration o ka lepo. Kēia pūʻulu nā a me leeches, i mea pinepine ia i loko o kēia lāʻau lapaʻau. Special waiwai i hirudin hua mai la ma ka leech, e like me ka mea'ōpuʻu hou i ke koko, a ua hoʻohana 'ia i loko o Anati-thrombosis a me nā pilikia maʻi.
