Yu dɔn ɛva wɔnda aw yu at de bit so ɔltɛm, so prɛsishɔn? I tan lɛk se klok in an de tik, we nɔ gɛt ɛnitin fɔ du wit am, ɛvride, fɔ lɔng lɔng tɛm... Dis nɔto jɔs ɔda tin. Wan rili wɔndaful ilɛktrik sistɛm de insay wi at. Na dat wi kin kɔl di Kadiak Kɔndɔkshɔn Sistɛm. dis na lεk sכmכl ‘ilεktrik waya sistεm’ na di at insεf. Lɛ wi tɔk bɔt dis wɔndaful sistɛm insay simpul wɔd dɛn tide.
Wetin na di kadyak kɔndɔkshɔn sistɛm?
Fɔ tɔk am simpul wan, di kɔndɔkshɔn sistɛm na yu at na wan nɛtwɔk we gɛt spɛshal sɛl dɛn, no dɛn, ɛn ilɛktrik signal dɛn. Ɔl dɛn tin ya kin wok togɛda fɔ mek yu at kɔntinyu fɔ bit. Jɔs lɛk aw os nid waya fɔ ɔn di layt, na so yu at nɔ go ebul fɔ du if i nɔ gɛt am.
Tu men kayn sɛl dɛn de we de kɔntrol aw wi at de bit:
- Kɔndɔkt sɛl dɛn: Na dɛn wan ya kin kɛr ilɛktrik signal. Dɛn tan lɛk smɔl mɛsenja dɛn.
- di mכsul sεl dεm: Na dεn wan ya de kכntro di kכntrikshכn dεm na di at. Dat min se di at de ‘pamp’.
Dɛn ilɛktrik signal ya kin tɛl di at ustɛm ɛn aw fɔ pɔmp blɔd ɔlsay na di bɔdi. Tink bɔt am lɛk pɔsin we de kɔntrol trafik, we de mek di at wok di rayt tɛm.
Aw dis sistɛm de wok?
di kכndukshכn sistεm na yu at na in de gi di signal fכ stat at bit. I kin tɛl difrɛn pat dɛn na di at bak ustɛm fɔ kɔntrakt ɛn ustɛm fɔ rilaks. dis prכsεs we de kכntrakt εn rilaks na in de kכntro di fכ fכlכ blכd tru di at εn כlsay na di bכdi.
Nɔmal wan, dis ilɛktrik kɔndɔkshɔn sistɛm kin mek di at rit wan we nɔ de chenj, ivin . I kin ɛp bak fɔ mek yu at bit kwik kwik wan we yu nid mɔ blɔd ɛn ɔksijɛn (fɔ ɛgzampul, we yu de du ɛksɛsayz) ɛn fɔ mek yu at rit slo we yu de rɛst.
Wetin kin apin we di at de bit, stɛp bay stɛp
εvri at bit, ilektrikal signal dεm de travul along di hat in kכndukshכn path. Dis na di sem tin lɛk aw kɔrɛnt kin pas tru waya dɛn we de insay wan tin we dɛn kin yuz na os. i kin stat wit wan εksayz signal we de kכmכt frכm wan pat pan yu at we dεn kכl di sinoatrial (SA) node .
Dis stimulus signal de travul lεk dis:
1. di atria (di כp chεmba dεm na di at): dis signal de fכs go na di atria. Dɔn di atria dɛn kin kɔntrakt.
2. Atrioventricular (AV) node: nεks, di signal de go na di AV node. Na ya, di signal de delay smɔl. di rizin fכ dis na fכ gi כl di bכdi we de na di atria tεm fכ muv to di lכw chεmba dεm na di at.
3. Bundle of His: afta di AV node, di signal de travul along dis bundle of His to di Purkinje fayb dεm.
4. Sεl dεm (Ventricles - di lכw chεmba dεm na di at) via Purkinje fayb dεm:We di sɛl dɛn dɔn gɛt dis signal, dɛn kin kɔntrakt. Na da tɛm de dɛn kin pɔmp blɔd kɔmɔt na di at ɛn ɔlsay na di bɔdi.
we dεn stεp dεm ya kam togεda, na wan komplit kכntrikshכn fכ di at mכsul. Di ilɛktrik kɔndɔkshɔn sistem na yu at kin sɛn bɔku bɔku pan dɛn signal ya ɛvride, ɛn dis kin mek yu at bit ɛn nɔ stɔp. Yu nɔ tink se i wɔndaful?
Wetin na di men pat dεm na di kadyak kכndukshכn sistεm?
difrεn spεshal sεl dεm εn no dεm de na yu at in kכndukshכn sistεm we de kכntro yu at bit. Dɛn na:
- Sinoatrial node (SA node) .
- Atrioventrikular node (AV node) .
- Bundle of His (atrioventrikul bכndεl) .
- Purkinje fayv dɛn
Naw lɛ wi luk ɛni wan pan dɛn pat ya smɔl mɔ.
Sinoatrial node (Sinoatrial - SA node) .
yu sinoatrial node (SA node) na di at in nεchכral pesmaker. I tan lɛk di ‘bɔs’ na di at. Na di wan we de sɛn di ilɛktrik impuls dɛm we de mek di at bit. sכmtεm, if di SA node nכ de wok fayn, di lכw pat dεm na di kכndukshכn sistεm de akt lεk εlpכ peshכn sεl dεm.
di SA node de na di כp pat na di rayt atria na di at. spεshal wan, nia usay di supεriכr vena cava, we na big vein we de kכri bכdi we nכ gεt כksijεn kכmכt na yu bכdi to di at, de jכyn di atrium.
yu כtonom nεv sεstem de kכntro aw fast כ slo di SA node de sεnd ilektrikal signal dεm. Dis pat pan di nervɔs sistɛm de pul ɔmon dɛn we de kɔntrol yu at rit bay wetin yu de du. Fɔ ɛgzampul, yu at kin bit mɔ ɛn mɔ we yu de du ɛksɛsayz ɛn i kin go dɔŋ we yu de slip.
di כtonom nεv sεstem gεt tu men pat dεm:
- di simpatik nεv sεstem: Dis de sho se di ‘fayt כ fכ flay rεspכns’. i de aktibכt di SA node, we de mek di at rεt go כp.
- di parasympathetic nervous system: dis de sho se di ‘rεst εn digεst rεspכns’. i de slo di SA node εn i de slo di hat rεt.
Atrioventrikular node (AV node) .
yu atrioventricular node (AV node) de nia di sεntrכm pan yu at. i de du dis bay we i de dilay di ilektrikal signal frכm di SA node fכ wan sכm tεm (wan frakshכn pan wan sεkכnd) εvri tεm.
dis delay rili imכtant biכs i de mek sכh se כl di bכdi we de na di כp chεmba dεm na di at (atria) dכn pas insay di lכw chεmba dεm (veins) bifo dεn stכp fכ kכntrakt.
di atria na di wan dεm we de tek bכdi frכm di bכdi εn sεnd am to di sεl dεm.
Bundle of His (atrioventrikul bכndεl) .
di bכndεl fכ His na bכndεl fכ fayv dεm (nεv sεl dεm) we de kכmכt na di AV no. dis bכndεl fכ fayv dεm de gεt di ilektrikal signal frכm di AV node εn i de kכri am to di Purkinje fayb dεm.
di bכndεl fכ di ia dεm de rכn along di wכl (septum) we de separet yu rayt εn lεft vεntrikl dεm. Dis bɔndɛl ia gɛt tu men branch dɛn:
- di lεft bכndεl branch: dis de sεnd ilektrikal signal to di lεft vεntrikl tru di Purkinje fayb dεm.
- di rayt bכndεl branch: dis de sεnd ilektrikal signal to di rayt vεntrikl tru di Purkinje fayb dεm.
Purkinje fayv dɛn
di purkinje fayb dεm na wan nεtwכk fכ spεshal nεv sεl dεm we de transmit ilektrikal signal kwik kwik wan to di rayt εn lεft chεmba dεm na yu at. di purkinje fayv dεm de na di wכl dεm na yu vεntrikl dεm, di insay layt we de layn di chεmba dεm na yu at.
we di Purkinje fayv dεm de sεnd ilektrikal signal to yu sεl dεm, di sεl dεm de kכntrakt. afta dat di bכdi de fכlכ frכm di rayt vεntrikl go insay di pulmonari atεri dεm εn frכm di lεft vεntrikl go insay di aorta. di pulmonari at dεm de kכri bכdi go na di lכng fכ pik כksijεn. di aorta na di big at na yu bɔdi, ɛn i de kɛr blɔd frɔm di at to di ɔda pat na yu bɔdi.
Aw dɛn pat ya kin luk?
Dis na rili smɔl pat dɛn. fכ egzampl, di `SA` node na lεk 15 milimita lכng (we de lεk di sayz fכ wan stepla pin) εn lεk 4 milimita waid. di `AV` node na lεk 5 milimita lכng εn waid (bכt di tip fכ wan layt switch). Dɛn se di bɔndɛl we In, in branch dɛn, ɛn di Purkinje fayv dɛn togɛda tan lɛk tik we dɔn ɔpsayd. Di bɔndɛl we In ɛn in branch dɛn gɛt tan lɛk tik in trɔnk, ɛn di Purkinje fayv dɛn tan lɛk tik in branch dɛn.
