Pulmonary kutenderera

Muvanhu, kufamba kweropa ndiko namahwindo hunhu. Akavhara nokuti hapana kutaurirana pamwechete kwokunze kwezvakatipoteredza. Uyezve, kuparadzirwa kwevanhu ruzere uye kaviri. Pedzisa inonzi nokuti ropa (venous uye arterial) haana kuvhenganiswa.

The muviri anosunungura makuru uye diki kweropa. Panewo wechitatu. Anonziwo "mwoyo" uye anoita mabasa zvikuru kukosha.

Lung (diki) akaparadzirwa kunotanga zvakanaka ventricle. The chikuru basa ndiro ropa okisijeni saturation iri kubviswa kuti carbon dioxide. Mumapapu pane kupanana magasi.

Small kuparadzirwa ndeiyi. Poor oxygenated ropa (venous) anopinda kubva ventricle (kurudyi) ari pulmonary hunde. Hunde (pakukura tsinga, iyo rwuripowo pulmonary riparadzirwe) rakakamurwa kuruboshwe uye arteries zvakanaka (pulmonary). Kubva kurudyi chokubuda kuenda kurudyi zvemapapu, kubva kuruboshwe - kuruboshwe, ukuwo. Uyezve kuparadzana kunoitika kakawanda pulmonary tsinga madiki.

Pulmonary kuparadzirwa zvinosanganisira capillaries kuti vari pedyo chaizvo zvakakodzera mukati pechiso mumapapu. pamusoro iri kushanyirwa chete mumhepo mhepo. capillaries Blood mudenga anosiiwa chete masvingo capillaries uye pachavo chiedza chaizvo dzakaonda rusvingo. zvipingamupinyi izvi zviri zvitete zvokuti chaiye ezvinhu, carbon dioxide inobvisa uye okisijeni anogona kupinda kuburikidza navo nyore. Saka, pane kuchinja zvikamu yepamusoro wevasungwa munguva migove maduku. Nokuti yokuti carbon dioxide inobvisa ari mutsinga zvakawanda, ruchapinda mumhepo, apo akagamuchirawo duku. Uye, sezvo mumhepo zvikuru okisijeni sezvo zvinoenda capillaries.

Vamwe pulmonary capillaries zvakabatana uye ichayerera mumidziyo guru. Avo, akavapindurawo, pinda mumidziyo yakatokura - the mutsinga. Mugumisiro mana makuru tsinga (pulmonary). Saka, pulmonary kuparadzirwa anouya mugumo muna atrium kuruboshwe.

kuparadzirwa nguva chete anenge mana kwemasekonzi mashanu. Pulmonary wokufambisa kunosanganisira kufamba venous ropa kuburikidza arteries, uye arterial - kuburikidza mutsinga.

Pane nguva yokuti dunhu zvakakwana. Panguva ino, ropa rinopfuura zvose madenderedzwa - uye diki, uye makuru. Panguva yokuzorora, zvinotora inenge maviri masekonzi matatu. Muscle makakatanwa anowedzera nokukurumidza. Somugumisiro kwemutemo ropa kuburikidza zvose madenderedzwa kunogona kubva vasere masekonzi pfumbamwe.

Achitaura tsvuku mvura kufamba mumuviri, zvinokosha kutaura pamusoro nhengo kuti vanobatanidzwa mairi. Saka, riparadzirwe dzinobatanidzwa ventricles uye atria, arteries, yeropa, capillaries, yakaderera uye yokumusoro vena cava, ari pulmonary capillaries uye arteries, mutsinga, ivo Formação de, coronaria.

Tichibatsirwa midziyo ropa kuenda kufamba pakati akasiyana zvomukati, nyama, uye mwoyo. Mumwoyo kuuya tsinga. Vakatuma ropa kuti nyama uye nhengo dzomuviri. Arteries akasiyana guru dhayamita uye gobvu masvingo kwakavharwa nenyama kuti anogona kukunda munhu zvakakwana yakakwirira kumanikidzwa (ropa).

Arteries akaumbwa anoshongwa akawanda: yomukati, wokunze uye pakati.

vascular lumen yaidzorwa tsinga (autonomic) uye anogona kuwedzera kana kutapudza nokushanda kwomudzimu kumeso netsandanyama. The kuwedzera kana kudzikisa achavaponesa zvinodiwa nomumwe kana vamwe muviri, uyewo pamusoro tembiricha hurumende yakapoteredza zvakatipoteredza.

Arteries mune nyama uye nhengo dziri kutamira mumidziyo pamwe lumen zviduku, pakupedzisira ndura capillaries. Mavari pane kupanana zvinovaka muviri uye zvimwe zvinhu zvinodiwa kuti upenyu pakati pamakamuri uye neropa. Capillaries, uyewo, kubatanidza arterioles uye venules.
