He aha holoholona i elua-o ke keʻena o ka naau? 'Ole a me ka holo

Ke koko o ka neʻeʻana o nā'aʻaʻa i loko o ke kino, nele i ke ano o ka EII ni, i ke kūlana o ka i ua häʻawi mai ai i ka naau Muscle. Ma ka simplest ola a pau, e like me na ilo, a chordates, kēia hui, kēia mea ma kahi'ē, a me ka 'ole o ka circulatory'ōnaehana - he paʻa apo. Fish i kekahi mau-o ke keʻena o ka naau e pushes i ke koko ma ka moku a hiki i na wahi a pau o ke kino i ke koko, e haawi ana ia lakou i komo i ka oxygen, ka mahuaola a me ka hoʻokuʻu 'ia, mai ka wehe aʻe o nā huahana, ae haawi aku ia lakou a hiki i na wahi? Aneii.

Like holo ulu

Na circulatory'ōnaehana - o ke kahua o ke ola no na mea he nui meaola e noho ana. Ia e hiki ke hoʻokō kona hana, i ke koko pono noke kūhōhō ma ke kino. Kahua o ka hoʻonaʻauao o? Acaeoey o na nenoai koko ka wā e noonoo pono i mea'ōnaehana mānowai koko 'ole o ka iʻa, amphibians, mea kolo a me na manu maopopo ike i.

1. Fish i anu-koko holoholona me ka paʻa circulatory kahua. Ka mea, i ka mau-o ke keʻena o ka naʻau a me ka hoʻokahi holo.
2. Amphibians a me nā mea kolo, he mau holo, kā lākou mau naʻau, ua maheleia i ekolu keʻena. Nā 'ia nō nā crocodiles.
3. Ma na manu, a me nā kānaka he nui loa holoholona kino e EII ni ke koko, ua poe e eha Panel, a me circulatory nenoaia - mau koʻikoʻi a hanohano.

Cardiac Muscle aelike, a propels koko ma na arteries, a i maheleia i na moku uuku, a hoʻomākaukau i nā wahi likeʻole o ke kino. A ma hope iho, e haawi ana i oxygen a me ka mea pono keia mau oihana mua ua ipu koko, haawiia keia i like aa koko, a hoi mai hoʻi waiwai.

Pehea ka naau hana ma ka iʻa

Animals me elua-o ke keʻena o ka naau, mau haawiia keia i like anu-koko. Ka mea, he mau 'elele o ka iʻa a me ka amphibian larvae. E like me ka noiʻi biologists ka poe i aʻo i ke kūpono 'ana o ke circulatory nenoaiu, ia mea maopopo i i loaʻa ka mua piha-e oniu kino i loko o ka iʻa. Mau anu-koko i nā keʻena ma luna-naau, i hoʻouna 'ia ai i ka atrium a me ka ventricle kiwikā nenoaiu. Circulatory'ōnaehana ano hoʻokahi nō nā pepeiao kaiapili, ke alualu venous koko.

Ke koko mai ka EII ni kolo ana ma ka capillaries o ka halo o kahi oxygenated, a hoopiha i ka wahi. Next o kona haawi aku i loko o capillaries aia i loko o ke kino nā'aʻaʻa, a me kā lākou saturation me ka oxygen. A laila, ua hele i na aa koko me ka oxygen ma, a huli i ka naauʻeke ma luna o lākou.

'ole

Primitive iʻa i elua-o ke keʻena o ka naau, a ua conventionally puunaueia i eha Hoʻohana:

• ka mua Hoʻohana - ua hoʻokaʻawaleʻia, i kapaʻia venous sinus, i mea kuleana no ka loaa ana i ke koko o oxygen nana i haawi mai i ke kino;
• ka lua o ka Hoʻohana loaʻa ka atrium me ka nohona kiwikā;
• kolu o Hoʻohana i kapaia o ventricle;
• i ka ha o ka Hoʻohana o ka aorticʻohana me kekahi mau kiwikā, i EII ni ke koko i loko o ka peritoneal aorta.

Once i ke koko i haʻalele i ka naau, e kolo ana maluna o ka halo o mua, a ua paʻa kūhohonu loa me ka o oxygen, a kahe ana i loko o ka spinal aorta, mai i ua puunaue ai i nā mea a pau kino nā'aʻaʻa.

Higher-mea iʻa a pau Hoʻohana i ole aia ma luna o ka mea ia laina, akā, i loko o ke kinona o ka palapala S, ma ka hope mau Hoʻohana mea ma luna o ka mea mua elua. Oia ka 'ole hoʻomaopop' ana i loko o cartilage a me Crossopterygii ka iʻa. Pokou 'elele OAOOUIEeE maule infundibulum, i ke ana i ho'ākāka' ia e like me ka hapa o ka aorta, a me ka ole o ka naau Muscle.

Description o Fish naau

Ke hoʻohālikelike i ka honua vertebrate naʻau iʻa liilii, a me ka nawaliwali. Kona kaumaha loli aʻe mai 0,3 a hiki i 2,5% o ke kino ke kaumaha. Aie i ka mea nāwaliwali hoemi i ka puʻe i loko o ka ipu ua i hoʻonāwaliwaliʻia. e hiki ke ola i ka hoʻohalahala winters me ka icing ma muli o ia mau 'ano o ka iʻa. I keia manawa, i ka iʻa naau aɃe pepehi ana, a me ka wā defrosting ka ho'ēmiʻana hana hou, a me ke koko hoʻomaka e kūhōhō ma ke kino, e lawe ana i ka iʻa mai hibernation.

Kēia hana o ka circulatory'ōnaehana aie i ka mea i iʻa i papamoe Aloha Hawaii, a noho i loko o ka wai, no laila,ʻaʻole nō he pono, e pahu aku ai i ke kahe o ke koko a me ka kaua o ka umekaumaha.

Hiʻona o ka hematopoiesis i ka iʻa

Ma ke kino, e hiki ke paka ke koko aeee mau nā loko o nā iʻa.

• halo o mua;
• ka intestinal mucosa;
• epithelium a me ka naau ipu;
• hakuʻala a me ka spleen;
• o na moku i ke koko;
• lymphoid nā loko, nā'aʻaʻa a me kroveobrazuyuschimi i hanaʻia ma lalo o ka uhi o ka cranium.

Fish koko he ulaula koko keena me ka nucleus i loko o ka waena. I kēia mau lāʻike'ōnaehana poe 14 koko pūʻulu.

Owai la ka mea'ē aʻeʻelua-o ke keʻena o ka naau

Me ka hoʻololi i ka holoholona ano honua kahi ola ano, a me ke kahua o ko lākou mau maʻiʻaʻai, Muscle a me ka wehewehe ana oia i na moku naau. Huikau hui o nā holoholona, a me ka naau o ka mau-keena i lilo iho i loko o ka Triple a me ka quad. Hana i ka lua o ka holo, a me ka naau Muscle e EII ni lilo ia i wale i ka venous akā, arterial koko.

Like hoike i na holoholona i ka hoʻomaka 'ana o ke ola mai o ka wai, i nā kānakaʻepekema alakai nā kuʻina o nā'ōlelo o amphibians, ka larvae o i mea elua-o ke keʻena o ka naʻau, a me kā lākou mau circulatory'ōnaehana o ka ia me ka iʻa.

Ma nā mākua, ka mea e hoʻomōhala ai he ekolu-o ke keʻena o ka naau, i ua poe e ka atria elua a me ventricles. Amphibians i ka holoholona mua ma i loaʻa i ka lua o ka holo.

Oxygenated ke koko mai ka ia maʻiʻaʻai a me ka ili accumulates i loko o ka atrium hema, a ua kaawale ma ka paku, mai hoʻohuihui me ka venous, i komo i loko o ka atrium akau.

Ke paneʻana i ka ninau e pili ana i ka holoholona i elua-o ke keʻena o ka naau, ua maluhia olelo hiki i loko o nā mākua ua malamaia ia i ke kino wale i ka iʻa a me ka amphibians - i loko o ka larval ke kahua.
