Inotungamirwa, Secondary dzidzo uye zvikoro
Hurongwa kuti sangana ose nhengo: huru vasiri uye dzichipfekeka mugadziriro zvipenyu
Hurongwa kuti sangana ose zvomukati, aizivikanwawo dzichipfekeka gadziriro. Zvivako idzodzo chirimwa uye mhuka zvinenge zviripo kuti zvakazara basa rayo.
Chii kwegadziriro zvomukati
Hurongwa kuti sangana ose nhengo vanomiririra uwandu hwezvinhu zvose zvabatanidzwa. kwavo yomuka nokuda ravaigona zvinhu. Kakawanda munhu nemamiriro muviri hakusi kugona zvakazara kuita imwe basa. Saka, vakuru ikashandiswa munyika. Ndivo siyana ari mamiriro. Somuenzaniso, mugadziriro nhengo emhuka vanoumba anopfuura gumi uye nechokwadi mashandiro yose muviri.
Mugadziriro zvomukati yemhuka
The runoratidza kukwanisa mhuka kuti heterotrophic muitiro kuti rinoita simba uye makumbo achada. Vari anounzwa rimwe-celled uye zvipuka zvine masero akawanda siyana. nenhengo dzawo (ona tafura pazasi rine ruzivo pamusoro dzinokosha zviri nechivako ravo) vane imwe specialization. Zvisinei, vamwe vavo mabasa akawanda mabasa. Somuenzaniso, kufema uye kweropa gasi Exchange rinoitwa mumuviri.
Nhengo hurongwa: tafura
Zvakakurukurwa sechivako mhuka nhengo hurongwa vari kupiwa zvinotevera tafura.

The nhengo mumhuka zvinomera: huru misiyano
Zvino funga mukuru muviri urongwa zvipuka zvine masero akawanda chirimwa zvipenyu. Ivo, semhuka, akaumbwa masero, izvo ikashandiswa mune tishu. Heino musiyano wokutanga. The miti vanoumba kushandiswa miviri yokufukidza, zvinokosha, zvemaziso, conductive uye dzidzo jira. In mhuka, zvakasiyana. Ichi ciliated epithelial, connective, tsandanyama uye tsinga. Saizvozvowo, nhengo kuti vanoumba, vachava akasiyana marongerwo uye mabasa anoitwa.
Next musiyano pakati pavo iri chokwadi kuti zvinomera regai kusunungura hurongwa. Achitaura pamusoro mamiriro avo, akadana pachivande muviri - mudzi, uyewo chikamu chiri panyika - kupukunyuka. The yokupedzisira, akavapindurawo, rine hunde uye mashizha. Hurongwa kuti sangana miviri zvose mhuka havasi chete vasiri, asi vo functionality wegadziriro.
Hurongwa kuti sangana ose nhengo
Somugumisiro, vose hurongwa vari revatema kupinda rakabatana uye pose, unonzi chipenyu muviri. Muvanhu, mitemo yaro basa nenzira mbiri: Neural uye humoral. Vane nzira dzakasiyana uye matambudziko nokukurumidza. Huta chengetedzo rinoitwa eponymous nhego hurongwa. kwokutanga chikamu dzahwo wotungira. Uchibatsirwa kwavo muviri anoona zvakasiyana siyana mashoko, iro vakabva dzikwanise pulses uye chakasvitswa kune runoenzanirana zvikamu nechepakati huta sitemy. Pane ari vanowanika sei muviri, unouya obrabratnom kutungamirira kushanda muviri. Last basa mashandiro ichi anenge pakarepo. Asi humoral chengetedzo rinoitwa zvakasiyana. Zvinotora nzvimbo achishandisa ari kwemakemikari anobudiswa omumuviri, izvo secrete kupinda ropa chaiyo zvinhu - mahormone. Ivo zvazvinoita siyana muviri mabasa. Zvavakaita zvakakwana refu. Somuenzaniso, kukura kemikari, izvo anosunungura ari pituitary shwanu, anosunungurwa panguva munhu kuti 20-25 kwemakore.
Saka, zvinonyatsorehwa urongwa sechivako zvipenyu ndiyo zvinotevera zvivako: masero, munyama, nhengo, nhego hurongwa. Recent chete tibudirire Implementation pamusoro akasiyana-siyana, ichipa yakarongeka ruzivo yose.
