A hagu ventricle na zuciya: tsarin, aiki, Pathology

mutane kuma mafi girma dabbobi masu shayarwa, da zuciya kunshi hudu da bẽnãye: biyu atria da biyu ventricles. Haka kuma, da tsari na ventricles kazalika da atria kasu kashi dama da hagu.

A hagu ventricle ne farkon da na tsari dabam dabam.

haltta

Post bar ventricle da hagu atrium via hagu atrioventricular bude, daga dama ventricle ventriculus daurin boye gaba daya ya zama ruwan dare interventricular septum. Daga wannan jam'iyya na zuciya ya fita daga lakã, da jini a kan shi cewa da aka wadãtar da oxygen ta hanyar karami arteries da dama zuwa ciki gabobin.

Ga alama hagu ventricle kamar wani inverted mazugi, da kuma kawai daya daga duk kyamarori da hannu a cikin samuwar zuciya koli. Saboda da manyan fiye da a dama ventricle, da size, an yi imani da cewa zuciya ne a kan hagu, amma a gaskiya shi ne kusan tsakiyar kirji.

hagu na ramin zuciya bango ne goma zuwa goma sha biyar millimeters m, wanda shi ne sau da yawa fiye da irin wannan Manuniya a dama ventricle. Wannan shi ne saboda mafi cigaba myocardium a gefen hagu saboda da hakan lodi. Wannan ne, da hakan da girma na aikin yi, da kauri daga cikin zuciya bango. A hagu ventricle Firaministan jini, musharaka a cikin tsari wurare dabam dabam, yayin da dama ventricle samar da jini girma ga kananan da'irar. Wannan shi ne dalilin da ya sa, a karkashin al'ada yanayi, da karshen ne talauci da dabarun, kuma ta kauri ne correspondingly ƙananan.

Atrioventricular sako (rami) a gefen hagu da aka rufe mitral bawul, kunsha na na baya da kuma agara leaflets. A gaban da aka located a cikin kusanci da interventricular septum, da kuma raya - zahiri daga gare ta.

Daga biyu fuka-fuki mika tsirkiya - agara strands cewa rike da sash ga papillary tsokoki. Ta hanyar wadannan tsokoki bawul, kuma ya aikata ta ayyuka, wato, a lokacin systole, babu wani dawowar jini baya cikin atrium.

Papillary tsokoki suna haɗe zuwa takamaiman tsokar protrusions (fleshy trabecula) wanda aka shirya a kan ciki da na ramin zuciya kogo. Irin wannan trabeculae ake musamman da kyau ci gaba a yankin na interventricular septum da kuma koli na zuciya, amma yawan su a hagu ventricle ne karami fiye da dama.

A tsawon da kuma yawan guitar na hagu ventricle mutum. Tare da shekaru, da tsawon hankali ƙaruwa, ana inversely alaka da tsawon na papillary tsoka. More sau da yawa fiye da ba da tsirkiya Ai daga daya tsoka a haɗe zuwa daya ganye. Bugu da kari, da gano guitar cewa connect da papillary tsokoki da trabeculae.

A wurin wani mafita na lakã ne da semilunar bawul, ta hanyar abin da na jini ba ya dawo daga lakã a cikin zuciya.

Jijiya turu a kan hagu na ramin zuciya myocardium shiga ta katako tsaki (hagu kafar). Ya kamata a lura da cewa kawai hagu ventricle bugun jini ne directed ta biyu rassan - a gaban kuma a raya.

Musamman na hagu ventricle da ayyuka

Dangi zuwa wasu sassa na zuciya, da hagu ventricle ne sauka, bayan da hagu. A m baki na ta more taso da aka kira wani huhu surface. A lokacin da rayuwar da girma na cikin masallãci ƙaruwa daga 5.5 cm ³ (ga jarirai) har zuwa 210 cm ³ (goma sha takwas zuwa ashirin da biyar).

A kwatanta da dama, hagu ventricle yana da mafi pronounced m da oblong siffar, da yawa daga tuhumar da kuma dan kadan fiye da shi.

A bar na ramin zuciya tsarin gano wani yawan sassan:

• Front (infundibulum) Magana da lakã ta cikin jijiya bude.
• Rear (a zahiri na ramin zuciya rami) cewa Magana da dama auricle.

Kamar yadda aka ambata a sama, saboda da more ci gaba da myocardium na hagu na ramin zuciya bango kauri ne goma sha zuwa goma sha huɗu millimeters.

Hagu na ramin zuciya aiki ne saki oxygenated jini a cikin lakã (ko a cikin tsari wurare dabam dabam), sa'an nan kuma ta hanyar wani cibiyar sadarwa na kananan jijiyoyi da kuma capillaries auku abinci gabobin da kyallen takarda da dukan kwayoyin.

Physiology

Karkashin al'ada yanayi, da hagu da kuma dama ventricles sarrafa synchronously. Aikinsu faruwa a biyu bulan: systole da diastole (da bi, da ƙanƙancewa da shakatawa). Systole, bi da bi, ne zuwa kashi biyu lokaci:

1. Awon karfin wuta hada asynchronous da Yanar gizo ƙanƙancewa.
2. Fitar: Ya hada da azumi da kuma jinkirin fitar.

Asynchronous ƙarfin lantarki halin m ƙanƙancewa na tsoka zaruruwa na myocardium, a sakamakon m rarraba zumudi. Atrioventricular bawul aka rufe a wannan lokaci. Bayan zumudi maida hankali ne akan duk tsokar zaruruwa, da kuma matsa lamba a cikin ventricles ƙaruwa, bawul din rufe, da rami da aka rufe.

Bayan aiki a kan na ramin zuciya bango a jini ƙaruwa zuwa tamanin mm Hg. v., da kuma bambanci da matsa lamba a cikin lakã ne 2 mm Hg. Art., Semilunar bawul buɗe, jini gudana a cikin lakã. Lokacin da wani kishiya halin yanzu daga aortic jini bude yatsun semilunar bawuloli Gasa.

Sa'an nan da na ramin zuciya myocardium hūta kuma ta hanyar da mitral bawul daga atrial jini shiga ventricle. A tsari sa'an nan Ya sãke.

Hagu na ramin zuciya tabarbarewa

Rarrabe systolic da diastolic tabarbarewa na zuciya da bẽnãye.

Lokacin da systolic na ramin zuciya tabarbarewa, rage ikon tura jini daga rami a cikin lakã, wanda shi ne mafi kowa hanyar zuciya rashin cin nasara.

Irin wannan tabarbarewa yakan auku saboda ƙanƙancewa na abin da ya faru, wanda results a cikin wani karu a bugun jini girma.

Hagu na ramin zuciya diastolic tabarbarewa - wani karu a cikin ikon cika da jini a rami (watau tabbatar diastolic cika). Wannan yanayin na iya haifar da sakandare hauhawar jini (duka venous da jijiya), wanda yana tare da dyspnoea, tari da kuma paroxysmal nocturnal dyspnea.

zuciya lahani

Akwai nakasar da samu. A karshen ne sakamakon disturbances a zamanin tayi zai kare. A category hada da nakasar sakon bawuloli, karin a hagu ventricle tare da ko dai m tsirkiya tsawon kogon septum tsakanin ventricles, transposition (mahaukaci location) na manyan tasoshin.

Idan akwai wani yaro na aibi atrial ko na ramin zuciya ganuwar, venous da jijiya da jini da aka gauraye. Yara da irin wannan nakasa ta hanyar hada su da transposition na da tasoshin da bluish fata, wanda da farko ne kawai alama.

Idan transposition ne ba kamar yadda wani ya zama ruwan dare aibi, hypoxia take kaiwa zuwa nan take mutuwa hari. A wasu lokuta (a lõkacin da ta detects aibi kafin haihuwa) ne mai yiwuwa a gudanar da aiki.

Gudanar da m magani wajibi ne, kuma ga sauran hagu na ramin zuciya lahani (msl, lahani na aortic bawul ko mitral bawul).

Hagu na ramin zuciya hypertrophy
