Injini inoshamisa yemuviri wedu: Ngatidzidzei zvese nezvemoyo!

Wakamboisa ruoko rwako pachipfuva chako panguva yakanyarara wovhara maziso ako woteerera here? Ruzha irworwo rwekuti "lub-dub... lub-dub..." rwaunonzwa uye rwaunonzwa ndirwo humbowo hukuru hwekuti uri mupenyu. Ruzha irworwo runobva kuinjini inoshamisa zvikuru, isingamiri mumuviri wedu. Ndiyo mwoyo yedu. Tinoziva here nezvenhengo iyi diki inoshanda isina kana sekondi imwe chete yekuzorora kubva pazuva ratinozvarwa kusvika pazuva ratinofa? Nhasi, ngatitaurei nezvemoyo uyu unodiwa uyo hupenyu hwedu hunovimba nawo.

Moyo chii? Unopa basa rei kumuviri?

Zvichitaurwa zviri nyore, moyo inhengo yakasimba kwazvo, ine tsandanyama dzakakura sechibhakera chako. Ndiyo nzvimbo huru yekutenderera kweropa mumuviri wedu wese, sechiteshi chikuru chemabhazi muguta. Tinoidaidzawo kuti circulatory system.

Basa guru remwoyo nderekupomba ropa mumuviri wese. Zvino ungave uchifunga kuti, "Saka chii chinoitika kana ropa richipombwa?" Funga nezvazvo, mamiriyoni emasero madiki mumuviri wedu anoda simba neokisijeni kuti ashande. Sezvatinoda chikafu nemweya kuti tirarame. Saka ropa rinopombwa nemoyo ndiro rinotora okisijeni nezvinovaka muviri rozviparadzira kumasero ese mumuviri. Ndiro rinounganidzawo marara akaita secarbon dioxide anoungana mumasero paanenge achishanda uye anoaendesa kunhengo dzakakodzera (senge mapapu neitsvo) kuti araswe.

Kwete izvozvo chete, moyo unoita mamwe mabasa akakosha:

• Inodzora mutinhimira uye kumhanya kwekurova kwemoyo. Uropi hwedu netsinga zvinoudza moyo wedu kuti urove zvishoma nezvishoma patinenge takarara uye nekukurumidza patinenge tichimhanya.
• Kumanikidzwa kweropa kunodzorwa. Ibasa remoyo zvakare kuchengetedza kumanikidzwa mukati metsinga dzeropa padanho rakakodzera.

Mwoyo haushande wega kuti uite basa iri nemazvo. Sisitimu yedu yetsinga nesisitimu yeendocrine zvinoshanda pamwe chete nemoyo. Sisitimu yetsinga ndiyo inopa moyo chiratidzo chekuti ukurumidze kana tichitya kana kufara, uye kuti uderedze kumhanya kana takasununguka. Mahormone anoburitswa nesisitimu yeendocrine anobatsira kudzora BP nekuita kuti mitsipa yeropa ivharike kana kuti ikure.

Tobvisa zvidimbu zvemoyo here?

Mwoyo wakaita sechivako chakagadzirwa zvakanaka. Une madziro, makamuri, magonhi, mapaipi emvura, uye sisitimu yewaya dzemagetsi. Ngatizvitarisei chimwe nechimwe chazvo.

Madziro nechifukidziro chemwoyo

Madziro emwoyo ndiwo tsandanyama dzinogonyana uye dzinokura kuti dzipombe ropa. Pakati pemadziro aya pane jira gobvu renyama, ratinodaidza kuti septum. Izvi ndizvo zvinoparadzanisa moyo kuita mativi ekurudyi nekuruboshwe.

Madziro emwoyo anoumbwa nezvikamu zvitatu zvikuru:

• Endocardium: Iri ndiro denderedzwa remukatikati.
• Tsandanyama dzemwoyo `(Myocardium)`:Iyi ndiyo tsandanyama yepakati, inonyanya kushanda.
• Epicardium: Iyi ndiyo jira rekudzivirira rekunze.

Mwoyo wese wakafukidzwa zvakare nebhegi rinodzivirira rinonzi pericardium . Mvura yakakosha iri mukati mebhegi iri inobatsira moyo kutsvedza usingarove dzimwe nhengo dzemuviri painorova.

Makamuri Mana eMoyo

Kune makamuri mana makuru mukati memoyo. Makamuri maviri padhoro repamusoro uye makamuri maviri padhoro repasi. Seimba ine nhurikidzwa mbiri. Tinoti makamuri ari padhoro repamusoro iAtria , uye makamuri ari padhoro repasi maVentricles .

Mavharuvhu emwoyo

Ropa parinoyerera richidzokera shure pakati pemakamuri emoyo, pane magedhi anorimisa kuti risadzokere nenzira isiriyo. Tinodana magedhi aya kuti "Valves" . Magedhi aya anovhurika kana ropa richiyerera kune imwe nzira, uye anovhara zvakasimba zvakare kana rimwe ropa raenda.

Kune mhando huru ina dzemavharuvhu:

• Vharuvhu ine tricuspid: Musuwo uri pakati peatrium yekurudyi neventricle yekurudyi.
• Vharuvhu remapapu: Mugero unotangira tsinga inotakura ropa kubva ku ventricle yekurudyi kuenda kumapapu.
• Vharuvhu yeMitral: Musuwo uri pakati peatrium yekuruboshwe neventricle yekuruboshwe.
• Vharuvhu yeAortic: Gedhi riri pakutanga kwetsinga huru (Aorta) inotakura ropa kubva kuventricle yekuruboshwe kuenda kumuviri wese.

Mitsipa Yeropa

Tinodaidza hurongwa hwemachubhu anotakura ropa rinopombwa nemoyo mumuviri wese uye richidzokera kumoyo kuti ``Mitsipa yeRopa.`` Aya marudzi matatu.

• Tsinga dzeropa: Idzi ndidzo tsinga dzakakora dzinotakura ropa rine oxygen kubva pamoyo kuenda kumuviri wese.
• Tsinga: Aya ndiwo machubhu anotakura ropa risina oxygen rinoshandiswa muzvikamu zvemuviri kudzokera kumoyo.
• Mapaipi: Mitsipa yeropa yakanaka kwazvo, yakatetepa sebvudzi inobatanidza tsinga netsinga. Mukati memapaipi aya ndimo munogashira masero okisijeni uye anobvisa carbon dioxide.

'Mafungu' emwoyo - kurova uku kunodzorwa sei?

Moyo hausi bundu renyama chete. Une sisitimu yemagetsi inonzi "Electrical Conduction System" inoita kuti urambe uchirova zvakanaka. Zvakafanana nesisitimu yekubatanidza waya mumba.

Kune zvikamu zvikuru zvehurongwa uhu:

• Sinoatrial (SA) node: Iyi ndiyo pacemaker yechisikigo yemoyo. Chiratidzo chemagetsi chinoudza moyo kuti kurova nekukurumidza kunotangira pano.
• Node yeAtrioventricular (AV): Izvi zvinotora chiratidzo kubva kuNODE yeSA, zvochinonotsa zvishoma, zvochitumira kumakamuri maviri epasi (atria) emwoyo.
• Zvimwe zvikamu (Bundle of His, Purkinje fibers): Izvi zvinotakura chiratidzo kubva kuAV node mumakamuri epasi emoyo, zvichiita kuti zvikanganise kamwe kamwe.

Nenzira iyi, mushure mekunge makamuri maviri epamusoro abatana uye apomba ropa, mukati mechikamu chimwe chete muzvikamu gumi zvesekondi, makamuri maviri epasi anobatana uye anopomba ropa kuenda mumuviri nemapapu. Kana paine kakanganiso kadiki muhurongwa hwemagetsi uhwu, ipapo kurova kwemoyo kusina kurongeka (arrhythmia) kunoitika.

Ndezvipi zvirwere zvinowanzo kanganisa mwoyo?

Sezvo moyo uri nhengo inokosha kwazvo mumuviri wedu, zvakakosha kuti tizive zvirwere zvinogona kuukanganisa.

Heano mamwe ematambudziko emwoyo anowanzoitika:

• Kusarongeka kwekurova kwemoyo (Arrhythmia): Moyo unorova nekukurumidza, zvishoma nezvishoma, kana kuti murhythm isina kurongeka.
• Cardiomyopathy: Kukora, kukura, kana kuomarara kwetsandanyama yemwoyo zvisina kujairika.
• Kurwara nemoyo / Myocardial infarction: Kuvharika kamwe kamwe kwetsinga yemwoyo inoendesa ropa kumoyo, zvichikonzera kushomeka kweropa neokisijeni kuchikamu chemoyo.
• Chirwere chetsinga dzeropa: Tsinga dzinoendesa ropa kumoyo dzinodzikira nekuda kwehuwandu hwezvinhu zvakaita secholesterol (tinodaidza kuti 'plaque').
• Chirwere chevharuvhu yemoyo: Magedhi emoyo, kana kuti mavharuvhu, atakataura nezvawo kare, haashande zvakanaka.
• Kukwira kweropa: Kumanikidzwa kuri pamadziro etsinga dzeropa kwakakwira kupfuura zvakajairwa.
• Cholesterol yakakwira: Kuva nemafuta akawandisa muropa.

Zviratidzo nemiedzo inoratidza dambudziko remwoyo

Kana paine dambudziko nemoyo, muviri wako uchakuratidza zviratidzo. Kana uine zviratidzo zvakaita seizvi, zvakakosha kuti uone chiremba nekukurumidza.
