Neuro-humoral system. Cai ntawm kev ua pa thiab nws cov nta.

Nyob rau hauv tib neeg lub cev regulates tag nrho cov tseem ceeb heev muaj dab. Xwm muab ob mechanisms uas yog siv rau lub hom phiaj no - ib tug tshee thiab humoral. Nws yog nrog lawv pab muaj thiab kev cai ntawm kev ua pa.

Ua tsis taus pa - tseem ceeb heev txoj kev nyob rau hauv peb lub cev. Cov pa system muab rau cov kev pauv ntawm CO2 thiab O2 ntawm tus kab mob thiab lwm cov ib puag ncig. Qhov no tseem ceeb heev tseem ceeb heev functions ntawm ntxawg heev heev Cns neurons, uas yog nyob rau hauv ob peb qhov chaw ntawm lub paj hlwb thiab ua ke nyob rau hauv ib tug generalized notion ntawm "ua pa chaw". Nws yog raug rau lub paj hlwb thiab humoral stimuli, yog li muaj yog ib tug zoo ua pa muaj nuj nqi ntaus ntawv mus rau ib puag ncig tej yam kev mob uas yog lossi hloov.

Tshee kev cai ntawm kev ua pa

Lug uas yog qhov tseem ceeb rau cov emergence ntawm pa rhythms twb xub pom nyob rau hauv lub medulla oblongata. Nws puas tsuaj ua rau ua pa raug ntes. Lub cerebral cortex yog ncaj qha mus muab kev koom tes nyob rau hauv cov kev cai ntawm kev ua pa. Uas yog vim li cas lub ntsws center yog nyob rau hauv qhov kev ua si. Nyob rau hauv nws muaj zoo excitation pulses thiab kaw zoo ua si. Ntxiv mus, pulses los ntawm qhov chaw los ntawm txoj kev centrifugal neurons yog kis tau mus rau lub pa nqaij thiab diaphragm. Yog li alternation yog nqa expiratory thiab inspiratory nyob rau hauv peb lub cev. Thaum mob stimulation, stimulation ntawm cov hlab ntsha receptor stimulation los yog cov kabmob nyob rau hauv lub plab kab noj hniav, cov pa hloov tshwm sim nkaus reflex.

Yog li, yog tias nqus tau cov pa ammonia pa taws, nws yuav khaus qhov ntswg mucosal receptors, uas tej zaum yuav raug nyob rau hauv ncua sij hawm ntawm cov reflex ua tsis taus pa txheej txheem. Qhov no yog los tiv thaiv lub cev, uas ua hauj lwm los mus tiv thaiv lub ntsws ntawm cov teeb meem roj. Cai ntawm kev ua pa tshwm sim thaum paj impulses los ntawm cov pa nqaij thiab receptors nyob rau hauv lub ntsws rau lawv tus kheej. Los ntawm cov pulses thiab nws nyob rau ntawm qhov tob ntawm nqus tau pa thiab exhalation.

Cai ntawm ua tsis taus pa tseem pab lub cev hloov mus rau tej kev hloov, xws li tuav koj ua tsis taus pa, ib tug neeg muaj peev xwm hloov nws tus kheej lub suab thiab qhov tob. Ncaws pob yog cov nyhuv uas cov cerebral cortex piav prelaunch hloov nyob rau hauv ua tsis taus pa, muaj zog lub plawv thiab nws cov groove ua ntej cov kev sib tw.

Humoral kev cai ntawm kev ua pa.

Nyob rau ua pa chaw muaj feem xyuam rau cov tshuaj muaj pes tsawg leeg ntawm cov ntshav, uas yog nws cov roj muaj pes tsawg leeg. Accumulates nyob rau hauv cov ntshav, carbon dioxide annoying receptors nyob rau hauv cov hlab ntsha uas nqa cov ntshav mus rau lub taub hau, thiab muab rau lub hauv paus ntawm reflections pa chaw. Cov nyhuv tib yam, thiab lwm yam khoom nrog acidity, uas nkag mus rau hauv cov hlab ntsha, xws li lactic acid. Nws cov ntsiab lus nyob rau hauv cov ntshav qab thaum lub sij hawm npag ua hauj lwm. Qhov no teb ntawm tus pa chaw hloov hauv lub xeev ntawm tus kab mob vim qhov tus ntawm lwm puag ncig yuav siv sij hawm qhov chaw instantaneously, nyob rau hauv ib tug teeb meem ntawm vib nas this. Tej zaum, yog li ntawd peb lub cev yog txhawj xeeb txog lub xeev ntawm peb noj qab haus huv thiab ceeb toom rau yav tom ntej los yog tab tom yuav phom sij. Humoral kev cai yuav tsum rightfully hu ua tus tshaj plaws ancient daim ntawv ntawm kev sis raug zoo nrog hlwb ntawm peb lub cev.

Tsis tas li ntawd, muaj ntau yam tsim nyog zog nyob rau hauv peb lub cev yog tswj los ntawm cov tshuaj hormones. Nws yog ib co active thiab thiaj li qhov tsim nyog lub cev tshuaj uas yog ua los ntawm lub endocrine qog. Secretory hlwb qog los ntawm nws saum npoo kev sib cuag nrog cov phab ntsa hauv cov hlab ntsha. Uas yog vim li cas lub hormones nkag mus hauv cov hlab ntsha sai sai. Lawv txiav txim rau lub cev ho.

Raws li koj tau pom, thiab lub paj hlwb thiab humoral kev cai yog ntawm kuj zoo kawg tseem ceeb rau lub tag nrho lub cev, tsis yog rau cov pa system.
