Tricuspid uye mitral valves
I-tricuspid uye mitral valve inonzi atrioventricular, sezvo inowanikwa pakati peatria uye mhepo inobhururuka mumakumbo ekurudyi uye ari kuruboshwe emoyo. Izvo zvinosanganisira zvipembenene zvakanyanyisa uye zvinoputirwa ne endocardium - tsvina yakatsetseka yakavhara mukati mukati memwoyo. Iyo yepamusoro yevhavhavha inotonhora, uye kune pasi kune mavara emakumbo anoshanda anobata mavara. Ivhavhavha ine magetsi matatu, uye mitral valve ine mavhavha maviri (inonziwo bivalve). The mitral valve yakatumidzwa zita rayo nekuda kwekufananidzirwa kwechimiro nemagetsi emubhishopu.
Chigadzirwa chemuputi valve
Iyo mapirmita arteri valve iri panotora nzvimbo ye pulmonary trunk kubva pane ventricle yakarurama. Iyo trumpet trunk inotakura ropa kubva pamwoyo kusvika pamapapu. Pasi pemapapiro emagetsi emapurmita mishonga mashoma masukari azere neropa uye kudzivirira kusungirirwa kwemagetsi kumadziro edu remapurmonary apo valve inotanga. Munguva ye systole yeAria, ropa rinopinda nepakati pezvinyorwa zvinotenderera uye mitral valve mumhepo. Munguva ye systole yemhepo inobhururuka, kukurumidza kushamiswa kwechisimba kunoita kuti kugadziriswa kwevhidhiyo inrioventricular. Izvi zvinodzivisa kudzokera kweropa kuAria. Mazai emagetsi anogadzirwa nemakwenzi, asingavabvumi kuti avhure nekuda kwesimba mumhepo. Mushure mokuvharwa kwevhiriji dze atrioventricular, ropa rinoyerera kuburikidza nemagavhuna emimunununu kusvika mumutumbi wepermonary uye aorta. Semilunar valves yakazaruka nekuda kwekumanikidzika kwakanyanya mumhepo inoputika uye kuparara nokukurumidza apo systemole inoguma uye diastole inotanga.
Chiitiko Chekuita
Uchishandisa phonendoscope, unogona kunzwa kuti kubatwa kwemwoyo kunofambidzana nekuonekwa kwemwoyo miviri. Izwi rokutanga rinowanika panguva yekuvhara mavheti e atrioventricular, uye wechipiri - panguva yekuvhara valve yemapurmonary artery ye aortic valve. Nzvimbo dzinotama kubva kumativi uye pasi pasi pemagetsi e-tricuspid uye mitral valve, uye zvino inotungamirirwa pasi uye yakabatanidzwa pamapurisa emapurundi anopinda mukati memhepo.
Nheyo yekushandiswa kwemakwenzi
Chords inodzivisa inverting yemagetsi emagetsi e atrioventricular kupinda muchechi yegungwa pasi pekuita kwekuwedzera kweropa mukati me ventricular systole. Izvo zvakabatanidzwa kumapapu ari pedyo, izvo zvinoita kuti vadzivirire zvakasimba munguva ye ventricular systole uye kudzivirira kuputika kweropa kudzokera kune atrium. The valor valve uye pulmonary artery valve inonziwo semilunar. Zvinowanikwa munzira yekubuda ropa kubva pamwoyo uye kudzivirira kudzoka kweropa kumhepo yakasimba panguva ye diastole. Chimwe chevhavha idzi mbiri ine hafu yemwedzi yakaumbwa mashizha, akafanana nehomwe. Izvo zvinosanganisira zvigunwe zvinobatanidza uye zvakaputirwa ne endothelium. Endothelium inoita kuti mabheji ave nyore.
