Neuro-humoral hurongwa. Mutemo afemeruke uye mamiriro ayo.

In womunhu anoita zvose zvinokosha kwendangariro. Nature inopa nzira mbiri inoshandiswa chinangwa ichi - a huta uye humoral. Ndizvo achibatsirwa wadzo uye murau kufema.

Kufema - inokosha muitiro mumuviri wedu. The kufema Hurongwa anopa kupanana CO2 uye O2 pakati nhengo uye kwokunze kwezvakatipoteredza. Izvi zvinokosha dzinokosha mashandiro anoita pamutemo vakawanda CNS Tutsinga tunofambisa mashoko utwu, izvo riri akawanda zvikamu uropi uye ikashandiswa mune generalized yokuti "kufema centre". Zvinonzi vachibatwa huta uye humoral mikana yakawanda yokukurudzira, saka pane zvakakodzera kufema basa mudziyo kune kwezvakatipoteredza ezvinhu zviri dzichichinja.

Huta mutemo kufema

Zvivako kuti zvinokosha kuti kwaita kufema mutinhimira zvakatanga kuwanikwa mune medulla oblongata. kuparadzwa kwaro kuupenyu kufema kusungwa. Cerebral cortex rinobatanidzwa zvakananga mutemo afemeruke. Ndokusaka kufema centre iri kugara basa. Mariri pane mutinhimira excitation pulses uye zvakanyorwa mutinhimira basa. Uyezve, pulses kubva pakati achishandisa Centrifugal Tutsinga tunofambisa mashoko utwu vari chakasvitswa kune kufema tsandanyama uye diaphragm. Nokudaro alternation rinoitwa expiratory uye inspiratory mumuviri wedu. Kana kurwadziwa dzishande, kweiyi ropa midziyo Kanotokonya kurudziro kana nhengo iri abdominal mhango, ari kufema kuchinja kunoitika zvachose dzepanguva.

Saka, kana inhaled amoniya chiutsi, zvichava ashatirwa nasal mucosal receptors, izvo zvingaita kuti munhu kunonoka pakati dzepanguva kufema kwacho. Izvi kudzivirira muviri, iyo inoshanda kudzivisa mumapapu anokuvadza gasi. Mutemo afemeruke kunoitika apo tsinga nomunhu achibva kufema tsandanyama uye receptors iri mumapapu pachavo. Kubva pulses izvi uye zvinoenderana ukuru inhalation uye nedzinovengwa.

Regulation wokufema zvinobatsirawo muviri zvinoenderana kwezvakatipoteredza kuchinja, akadai vakabata mweya wako, munhu anogona kushandura pachake mutinhimira ake uye kudzika. Vatambi ndiwo mugumisiro cerebral cortex inotsanangura prelaunch kuchinja kufema, vakawedzera mwoyo uye paburi raro pamberi makwikwi.

Humoral mutemo kufema.

On the kufema centre kunokanganisa makemikari Zvinoumba Ropa, kureva rayo gasi sezvamunoita. Rinoungana muropa, carbon dioxide kunetsa receptors muropa midziyo kuti takura ropa kusvikira musoro, uye vakatendeukira maererano zvichiratidza kufema pakati. Zvimwechetezvo, uye zvimwe zvigadzirwa pamwe acidity, vanopinda muropa, akadai lactic acid. kugutsikana Its muropa inowedzerawo panguva tsandanyama basa. Izvi kwaiita kufema nepakati kushandura mamiriro nhengo nokuda pokudzora kwomudzimu kwokunze kwezvakatipoteredza kunoitika panguva, panyaya mumasekonzi. Zvichida, saka muviri wedu kunetseka mamiriro utano hwedu uye anonyevera nezvengozi ramangwana kana kuuya. Humoral chengetedzo inogona yakakodzera kunzi kupfuura yekare muchimiro nekuita pamwe masero miviri yedu.

Uyewo, vazhinji zvakafanira mabasa mumuviri yedu nokudzorwa mahormone. Zviri kwazvo kushingaira uye naizvozvo zvakafanira muviri zvinhu kuti zvinoberekwa kwemakemikari anobudiswa mumasero. masero Secretory mumasero aro pemvura kuonana pamasvingo tsinga. Ndokusaka mahormone kupinda muropa nokukurumidza. chiito avo muviri yekudyidzana.

Sezvaunogona kuona, uye huta uye humoral mitemo zviri zvikuru nokuda muviri wose, kwete chete nokuda kufema hurongwa.
