The kweropa nyika shiri, tumbuyu uye arthropods

The kweropa maitiro shiri musiyano kweropa negadziriro nezvinokambaira: ndiko kuparadzana zvakakwana arterial uye ropa riyerere venous. Shiri chinhu mwoyo yavo guru. Uyezve, mune diki kukura shiri mwoyo yakakura uye mwoyo yekudyidzana zvikuru kupfuura guru ndivo.

BP kupfuura kaviri chokupika minhenga zvinokambaira uye mhuka. Izvi zvinoshandawo kune quantitative kugutsikana ropa, Chizenga, uwandu masero matsvuku eropa, uye kuti shuga zvirimo, uyewo okisijeni vanokwanisa. The kweropa maitiro shiri ine zvose zviri padunhu pamwero metabolic kwendangariro. A mwoyo guru uye akurumidze kupomba kuti nokukurumidza ropa kuparadzirwa munyika, pachiimbwa refu okisijeni chekuchengeta kugona uye mari vakawedzera kuti shuga kunogona inorema uye pakarepo saturate chinokosha uye vose nhengo pamwe zvinovaka muviri uye oxygen. Izvi zvinotungamirira kubviswa mapazi kubva shiri zvigadzirwa vakawana somugumisiro metabolic kwendangariro.

Moyo Quad shiri ine 2 atria uye 2 ventricles. On mutsinga zvikuru, venous ropa inounganidzwa zvakarurama atrium uye yakarurama ventricle Rwako. Pulmonary tsinga ngaubve kurudyi ventricle uye ipapo rakakamurwa mapazi kurudyi. Maererano naye, venous ropa ruchigona mumapapu, umo oxidized. Uyezve, oxides rimwe arterial ropa chinofamba kuburikidza mutsinga kuruboshwe atrium. The kweropa Hurongwa ane shiri mbiri kuparadzirwa (diki uye makuru). Large vanosanganisira ventricle kuruboshwe, rworudyi yeropa - huru tsinga, iro mbudo kubva pamwoyo vanoparadzaniswa sezvo arteries maviri: rworudyi uye akasiya zita. Iye kumashure pamusoro rworudyi bronchus achitevedza nomuzongoza, sezvo dorsal yeropa. Yazvakaitikira tsinga, vachichinjana, akakamurwa makarara, kuenda musoro, uye vakawanda subclavian. Subclavian tsinga rakakamurwa pamafudzi, kutungamirirwa bapiro tsandanyama, uye thoracal tsinga simba pakukoka mu tsandanyama yacho sternum.

Kubva hunde dzacho huru dorsal yeropa uye mesenteric visceral achizviparadzanisa, ivo kupa ropa kuti abdominal tsandanyama, ari nhengo ari pelvic mhango, hadzi makumbo, ura, dumbu.

The kweropa maitiro shiri anounganidza ari venous ropa kubva musoro shiri ari jugular tsinga, iyo, pamwe midziyo batanidza kupinda rworudyi uye nokuruboshwe nemhango mutsinga zvikasabudiswa kupinda zvakanaka atrium. Kubva munzvimbo cloaca, duku tsinga ropa ikaunganidzwa, ipapo akabatanidzwa pamwechete, pova huru nhatu.

Kweropa maitiro rezvipembenene haisi Akanyatsovharwa denderedzwa. Ropa hahuwanikwi zvachose mune tsandanyama Kamudzira, vasiyana musana, vamwe ropa crow uye anozadza voids uye nemaburi masangano.

Kwemakemikari anobudiswa mumasero secrete mahormone kuti huri hemolymph (ropa) nezvipembenene. Ivo ndivo vasiri kwendangariro. Nokuda ropa iri muviri Tupukanana pave womukati kumanikidzwa kuti anobvumira kuti mapapiro ayo, kunobatsira chirongwa molting, kuwedzera proboscis, inotsigira zvinyoronyoro mitumbi mamwe marudzi.

The kweropa maitiro rezvipembenene ine mwoyo, tichibatanidza matanho akawanda kuderedza kamera. Pangave kusvika 8. Somugumisiro, reductions muropa inofamba mumuviri. kuparadzirwa kwayo omurume nhengo kunoitika achishandisa pulsating Kamudzira - ampoules vari pemakumbo Tupukanana wacho.

Kweropa maitiro sezvo arthropods haisi Akanyatsovharwa denderedzwa. Zvomukati pamusoro arthropods vari in - sinuses vakazadzwa hemolymph kugeza zvomukati, zvino anodzoka mwoyo uye ropa midziyo. The kweropa kwava mwoyo arthropods - a nechepakati muviri (havana segmented nehonye), iro inovakwa nyore. Hemolymph haina zvinobatanidzwa chokufambisa negasi, basa iri kuteererwa trachea.
