Four-o ke keʻena o ka naʻau o nā amphibians a me nā mea kolo. Examples

I ka Honua ua densely na kanaka] na holoholona o kekahi papa, a me nā pūʻulu? Ueo. Ÿepekema i këia i ko lakou 'ole a me ka ooieoeiiaeuiiai manaʻo nui o kanaka nā loko. About ka ano o ka naʻau o nā amphibians a me nā mea kolo, heluhelu i ka 'atikala.

E like me ka naʻau o nā keʻena ekolu Ua lilo i ka quad?

Vertebrates landfall aie i ka mea i hoomaka i ko lakou pulmonary ka hanu, e hoʻomōhala intensively. Ke circulatory'ōnaehana hoʻomaka e kūkulu hou. Fish, ha me ka halo o mua, i ka pōʻai o ke koko holo, kā lākou naʻau ua haku o elua wale Panel. Lakou hiki ole e ola ma ka aina.

Three- a eha-o ke keʻena o ka naau, ua ano honua kahi vertebrates. Ka mea, i wehewehe aku ma ke alo o nā holo. Lākou paʻa kaianoho koholā - aina. Kino me ekolu keena i amphibians a me nā mea kolo. 'Oiai, ma kekahi laha' o nā mea kolo, he mea kāpili kona papa i eha hapa. Ka hooulu ana o ka eha-o ke keʻena o ka naʻau i loko o ke kaʻina hana o ka evolution i wahi ma ka laua i loko o mammals, manu, a me nā crocodiles.

Mea kolo a me amphibians

Kēia mau papa o na holoholona i loaʻa i nā laps i ke koko holo a me ka naau, iloko olaila o ekolu keʻena. Wale kekahi aniuea i ka hemahema, akā, he eha keena, o ka naau. Kēia crocodile. Full cardiac hui, muaʻikeʻia i loko o primitive mammals. I ka wā e hiki mai, o ka naau a me ka ili me nā hale o nā mamo o ka dinosaurs - na manu. Ua Ua ili a me kaʻiʻo nō o kēia mammals.

manu

Ua eha-o ke keʻena o ka naau manu. Manu OAOOUIEeE piha dissociation holo: nui a me ka meaʻuʻuku, e like me ka ke kanaka, i ka wa aole mea i hui pu iaʻi ke koko - arterial a me ka venous. Ka akau a me ka hema hapalua kino loa kaawale.

Manu Ua eha-o ke keʻena o ka naau, kona 'ole ua poe ma na atria elua a me ventricles o ka hookahi dala. Ke ventricle loaa ana deoxygenated koko mai ka atrium akau. Mai ka mea, he mea hookuuia o ka pulmonary artery, i ua maheleia i haʻalele a me ka pololei lālā. E like me ka hopena, i ka venous koko o loko o ka like akemāmā. I keia manawa i ke koko ua hikiwawe oxidized, a komo i ka atrium hema. Keia ua kapaia o ka holo ana o kana poe uuku p ÷ ai.

A nui kaiapili o ke koko holo originates mai ka ventricle hema. Ua haalele mai ka hookahi ipu, i kapaʻia he pono aortic e pio mai, i mea koke lalo iho o ka naau hoʻokaʻawale ka innominate artery elua: haʻalele a me ka pono. Ka loa ia aorta paa wahi i loko o ka bronchus akau, a me ka wahi o ka mahinaai, oia ia laua i ka vertebral kolamu ma ka 'auhau o ka dorsal aorta. Kēlā me innominate artery ua maheleia i loko o ka carotid a me ka subclavian. Ka mea mua e hele ai i ke poo, a me ka lua o ka hou māheleʻia i loko o ka pahu a me ka'ūhā mua. Mai ka dorsal aorta haalele i ka nui arteries. Unmatched ke hoʻololi e lawa i ka'ōpū a me ka naʻau liʻiliʻi me ke koko, a me ka mau - ka diawahine ia lala, pelvic nā loko a me nāʻiʻo abdominal pa.

Four-naau i ka manu, ka mea, ua wehewehe aku i loko i ka holo ana o ke koko o ka manu ua lawe maiʻano nui ma na moku o ka nui Ana, a me wale i ka hapa uuku wale no o ka mea hele aku i loko o kaʻaʻa puʻuwai capillaries. Manu oko ma ke alo o ka naau i ka nui me ka pinepineʻoki a komo i ke kino o ka wale maemae arterial koko. Ua 'ae' o ka huina manu mehana-koko holoholona.

Ke circulatory nenoaiu o mammals

Ma mammals, eha-o ke keʻena o ka naʻau o ke kanaka, a me na manu. Kona ho okumu mea he piha kaawale ana o ke koko holo koʻikoʻi a hanohano, kena ae la ia e ka nele o ka? Acaeoey o na ano like mehana-bloodedness. Kēia Ua wehewehe like penei: mehana-koko holoholona i kekahi mau hemahema no o oxygen, i mea hiki ke halawai wale i ke koko hala ole o na arteries me ka hailona o ka oxygen. Hōʻike i kona kino, ua hiki wale o ka eha-o ke keʻena o ka naau. A hui koko o vertebrates, ma a ka naau i ekolu keena, mea e hiki ke haawi aku i ka makemake kino mahana. No laila, ua kapaʻia anu-koko kēia mau holoholona.

Aie i ke koko, aole ia i hui piha i pohā. Great kaiapili holo kahe wale arterial koko, i ka makemake loa lako a pau na nā loko o ka ieaeiieoa, a kokua oia i i ka pūnao. Kēia kaʻina kōkua e malama i ka ikaika ana wela. Four-o ke keʻena o ka naau i mammals, manu, a me nā holoholona papa, i mea e pōʻino ai i ka mālama a me ka hale lio kino ana wela. Ano, ke kaiapuni i ole ia ma luna o lākou.

hana o ua moo

I mea, i ka naʻau o kēia mau mea kolo i ekolu keena mau atria a me kekahi ventricle. Akā, me ka loina o kana hana i mea e hiki ai i ka hoʻike i ka eha-o ke keʻena o ka naau, he mau hana o ua moo. Ka wehewehe ana o keia kŰia like penei. ua piha Venous lua me ka o oxygen-ilihune koko, i mea ke kumu o ka makahiki akau atrium. ua waiwai Arterial koko me ka o oxygen, ka mea, ua lako pū mai i ke ku pono atrium.

Pulmonary artery a me ka aorta, nā hōʻike. Ua makemake mea i pono e loa hui i ke koko. Akā, i kēia 'ole e hana, no ka mea, i ke alo o ke Muscle puapua i loko o ka huipūʻana me ka mau-pae ka ho'ēmiʻana i loko o ventricular naʻau hana a me ka pale hou koko hui pu iaʻi. He loaʻa, akā, ma ka liʻiliʻi loa mea. Nolaila, e like me ka iaea ooieoeiiaeuiiai cia o ka ekolu-o ke keʻena o ka naau o ua moo nei, e like me ka quad.

mea kolo

Crocodile i ka eha-o ke keʻena o ka naʻau, akā, i kēia lapaʻau ua i hookaawale i ke koko loa ma ka paku. I mea kolo hui, (naau) He kuleana no ka haawi i ka mana holoʻokoʻa o ke kino ma ke koko, ka mea i he kupaianaha 'ole. Ma waho aʻeo i ka pulmonary artery, e holo ana mai ka ventricle ma kaʻaoʻao'ākau, aia mea he hou, hema. Ma ka mea, i ka papa kuhikuhi nui o ke koko i loko o ka digestive nenoaiu.

Ma waena o nā arteries elua, pono, a haʻalele, o ka naau o ka crocodile i ka puka. Ma ia ia, i ke koko, mai na aa koko mea hiki ke kiʻi i loko o ka nui kaiapili lapaau, a me ka hope versa. ʻepekema, Ua lōʻihi manaoio aku i ka naau i ke ano o ka aniuea malumalu em ala hele i ka hooulu ana o ka piha naau o ka eha keena me ka mehana-koko mammals. Akā, i kēia mea,ʻaʻole i ka hihia.

manu kuhukukū

Ka'ōnaehana ana o na moku koko, a me ka naʻau o kēia mea kolo o ka ia e like me ia o nā mea kolo: naʻau me ekolu keʻena e pili ana ma kekahi aa koko a me ka artery. Ua hoomahuahua ia Contents lawa oxygenated ke koko i ka wa a ka mea mawaho puʻe, piʻi pū. Kēia kānāwai ka wā o ka holoholona luu a neʻe koke. Heart uku emi, oiai me ka nui loa mahuahua ka carbon dioxide i lehulehu.

Au ua eha-o ke keʻena o ka naau kuhukukū, eia nae ka physiological 'ole o ke kino i wale ekolu keʻena. Ka nui, e hoike ana i ka naau mea okoa honu kāpili ventricular paia a puni i ke koko oihana, a me kekahi mau dala o ka oxygen.
