Roundworms: he manawa pōkole ano o keʻano

Roundworms, a me ka mea, e haawi ia ia e like me nematodes, e meaola me ka iniiaiie kino lua. Lakou noho ana ma ka loa like wahi ma luna o ka Honua - na kai, wai a me ka lepo. Kekahi 'elele i parasites - mea nei ma ka lilo o ka mea kanu a me nā holoholona meaola. Ka loa kaulana i kanaka parasites a me roundworm Trichinella.

Type Roundworms: mall hiʻona. Ka inoa nani nui mai nei i ka 'ole o ka elele o kēia' ano - i loko o keʻa-pauku ka mea, i ka poepoe shape. Lākou kino He fusiform, a hou ma nā wēlau, e hiki maopopo iho la i ike i ke poʻo ma luna o ka mua hopena. symmetry kinoʻano -ʻeluaʻaoʻao.

Like no ka nui o kēia mau meaola, ka mea hoano e loa - mai ka microscopic (80 microns), i aneane he kanaka nunui (oi ma mua o 8 mika o ke kohola parasites).

Lākou kino ninoieo o ka ili-Muscle kieke i mea hoʻokaʻawale, mai ka na nā loko o ka iniiaiie lua, a psevdotselem. Ua uhi ia ka ili me ke anuanu, ahu iho ma luna o ka cuticle, i ua ua loaʻa epithelium mawaho integument.

Roundworms: ka 'ole o ka digestive nenoaiu. Digestive'āpana ma keia pae ana o meaola. Una puka manaʻo ma ka mua pau ana o ke kino a me ka hoʻopuniʻia e lehelehe a me Muscle'aʻaʻa. Ua hiki aku i ka muscular pharynx, a ua hoʻohana 'ia no ka hana omoʻai. I ka ai a laila, komo i loko o ka waena, a laila, i loko o ka hindgut. e kipaku metabolic huahana ma ka anus i ka wahine a me ka poe kane a pau cloaca.

He hana hoihoi ia kekahi parasitic meaola o kēia 'ano o ka digestive Tube, a ua lilo iho la ka uuku eke meʻaʻohe puka.

Roundworms: ka hanu a me ka excretion. Excretory nenoaiu roundworms nani. Kēia loaʻa he nui hookahi-aeea cervical glands. Ke metabolic huahana loaa i loko o ka lua loli, ma hope a ka lonikū kīloi paʻewa auwai a elua e hoʻoneʻe i ka hao, a hookuu ana i ka waho. Ka'ā'ī i ka hookaawale hao excretory hamama i weheʻia i loko o ka abdominal hapa o ke kino. Kekahi metabolites, e like me ammonia, e kipaku ana ma ke kino pa.

Like no ka hanu 'ana, mai ka' papahana no nā nā loko o ole meaola. Oxygen ma ka paka ma ka intestinal nā'aʻaʻa. Ma ia hihia, ina oe i ke ola i loko o ana o ka o oxygen pololi, roundworms hiki ke hele i ka anaerobicʻano o ka hanu.

Roundworms a me kā lākou ko mākou hopohopo kahua. ʻO ko mākou hopohopo'ōnaehana i loko o kēia mau meaolaʻano primitive, o ka oi aku i loko o parasitic 'ano apau loa. I ka papa kuhikuhiE associative-oaio? A hooku iho la ia peripharyngeal nā aʻalolo ganglia, mai i nā aʻalolo nui ilpko o hele aku.

Like no me ka makaukau no, ka mea, e hōʻike mai iā ia papillae, setae, a me amphids drugiemi me ka ho okumu. A pau i kēia - na kino o ka mea ma paʻi, Nine Inch, a me ka malamalama pā lonoaʻili. Ma keia ano o ka parasites makaukau i emi e hoʻomōhala ana i mua o ka noa palapala.

Roundworms: nā'ōlelo. Me ka Poeikohoia o kēia 'ano o nā holoholona i dioecious meaola. I ka Ia manawa malaila, a hala loa kekahi 'moe dimorphism - na kane hope hope ka manao i ka ventral hapa o ke kino.

Female anal nā loko i na poe ma na ovaries, uterus a me oviducts. Ke kane i hoʻi, vas efferens a me ejaculatory leki uea. Ke kane spermʻoe i loko o ka vagina o ka wahine copulatory hui, ma. Interestingly, ka sperm i flagella, ua kaupalena 'ka hoʻoneʻe, a amoeboid shape.

Nā Roundworms i okoa mai ka pelane? I mea, na nä mea ma waena o nā 'ano mau o nā holoholona,ʻo ia nō kekahi'. E hoʻomaka, e pono ke kuai i olelo ia e pili ana i ke kinona o ke kino - he keʻa-mahele Flatworms i ka flattened kino. Kekahi mea nui koena unuhi - keia mea i ka iniiaiie kino lua, i mea noho e makou i na elele o flatworms. Eia hou, i ka nematode mea paa malaila-ma ka digestive nenoaiu. It E e hoʻomaopopo i ka mea i lalo ilo - hermaphrodites.
