Inkqubo yegazi of iintaka, izinambuzane kunye arthropods

Inkqubo yegazi ezintakeni kukho umahluko omkhulu ukuba inkqubo yokujikeleza izirhubuluzi: ukuba umsantsa olupheleleyo lwemithambo kunye ithombo legazi lwemithambo. osemqoka ezintakeni intliziyo yabo enkulu. Ngaphezu koko, ubukhulu iintaka ngentliziyo encinane enkulu kunye nokubetha kwentliziyo kakhulu ngakumbi kunokuba ezinkulu.

wegazi ngaphezu kabini ukusebenza izirhubuluzi ngeentlobo kunye nezilwanyana ezanyisayo. Oku kusebenza isiqulatho ubungakanani igazi, ihemoglobin, inani elipheleleyo iiseli ezibomvu, nokuba isiqulatho iswekile, kwakunye oksijini amandla. Inkqubo yegazi yeentaka zonke iimpawu kumgangatho ophezulu iinkqubo metabolic. Intliziyo enkulu kunye ukubetha kwentliziyo ngokukhawuleza ukuba kwegazi olukhawulezisiweyo igazi kule nkqubo, libambisene ne eliphezulu oxygen umthamo yokugcina kunye kwenani zeswekile kunokuba nzima yaye ngoko nangoko kuwanelisa laphu yaye onke amalungu izakhi kunye neoksijini. Oku kukhokelela ekususweni amalungu nasezintakeni imveliso afunyenwe ngenxa yeenkqubo metabolic.

Intliziyo Quad intaka iquka imithambo-2 kunye ventricles 2. On emithanjeni ezinkulu, igazi lwemithambo abayiqokeleleyo intendelezo ekunene kunye nomthamo ventricle ekunene. pulmonary isuka ukusuka ventricle ekunene uze emva koko yahlulwe amasebe ekhohlo ne ekunene. Ngokutsho kwakhe, igazi lwemithambo idla imiphunga, apho oxidized. Ngaphezu koko, oxides of igazi esimbaxa ezihamba imithambo intendelezo ngasekhohlo. Inkqubo yegazi iye iintaka ezimbini ejikeleza (ezincinane nezinkulu). Large iqulathe ventricle elisekhohlo, aorta ekunene - kwemithambo ephambili, ukusuka apho ephumayo ukusuka entliziyweni yahlukanisiwe nemithambo ezimbini: ilungelo kunye ongenagama ekhohlo. Yena ngokwakhe emva bronchus uhambe emqolo, njengoko aorta amaphiko. Umthambo ngagama, elowo kuthi, yahlulwe ukulala, ukuya entloko, yaye subclavian enkulu. Umthambo Subclavian yahlulwe emagxeni, mayibhekiswe izihlunu zeentlobo ngeentlobo, kwemithambo thoracic enamandla esukela kwezihlunu kwentamo.

Ukususela iziqu ezinkulu aorta amaphiko kunye enoxolo mesenteric visceral, nikeza igazi kwizihlunu esiswini, amalungu ka kwisisu zangasese, imilenze nemazi yexhama, amathumbu, isisu.

Inkqubo yegazi yeentaka uqokelela igazi lwemithambo lathabathela entloko le ntaka kule ndlela jugular, leyo, kunye neempahla bahlanganisane ukuze ekunene ngemithambo ekhohlo nomgongxo ekufunxeni kungena intendelezo ekunene. Ukususela kummandla cloaca, igazi ndlela encinane lwaqokelelwa, ngoko zadityaniswa ndawonye, ukwakha ezintathu ezinkulu.

isimiso izinambuzane ayikho isangqa esivalekileyo. Wegazi akanakuxoka ngokupheleleyo philisi kwezihlunu, eqhotyoshelwe kule umva, njengabanye uhlamba igazi Wawuzalisa imigodi kunye izikhewu phakathi arhente.

amadlala Ezingokuqandusela hormone ukuba ziqulethwe hemolymph (igazi) izinambuzane. Abanoxanduva nokomzimba. Ngenxa igazi kumzimba sinambuzane kudala uxinzelelo lwangaphakathi ekuvumela ukuba Yolule amaphiko ayo, inceda inkqubo kuhluma, ukwandisa umboko, ixhasa imizimba ezithambileyo kwezinye iintlobo.

Inkqubo yegazi izinambuzane iqulathe wentliziyo, edibanisa amanyathelo aliqela ukunciphisa lwecamera. Kusenokubakho ukuya ku 8. Ngenxa yoko, nokuncipha lihamba igazi emzimbeni. ekujikelezeni kwawo amalungu ayamileyo kwenzeka ngokusebenzisa inwebu eliguquguqukayo - ampoules abakulo imilenze yayingooqongqothwane.

isimiso njengoko arthropods ayikho isangqa esivalekileyo. Izibilini yangaphakathi arthropods ukuba angabi nemingxuma - sinuses ezaliswe ngokuhlamba hemolymph enyama yangaphakathi, ngoko ibuyisela ezityeni ngentliziyo negazi. Le nkqubo yegazi ke intliziyo arthropods - umzimba esembindini (musa ukuba worms abamnkela), nto leyo yakhiwe nje. Hemolymph akazibandakanyi ukuthutha kwegesi, lo msebenzi wenziwa uqhoqhoqho.
