Li-valve tse thata le tsa metral
Li-valve le li-mitral li bitsoa atrioventricular, kaha li teng pakeng tsa li-atria le li-ventricle ka ho le letona le le letšehali la pelo. Li na le lihlahisoa tse nyenyane tse sebetsang 'me li koahetsoe ke endocardium - e leng lesela le tšesaane le koahelang ka hare holimo ea pelo. Karolo e ka holimo ea li-valve e boreleli, 'me ka tlaase ho na le likhetho tse sebetsang tse sebetsang ho kenya libukana tsena. Vuvu e entsoeng ka tricuspid e na le li-valve tse tharo, 'me valve ea mitral e na le li-valve tse peli (e boetse e bitsoa bivalve). Sephara sa mitral se na le mabitso ka lebaka la ho tšoana hoa sebopeho le sekontiri sa mobishopo.
Sethapo sa methapo ea lipatlisiso
Sethapo se entsoeng ka methapo ea pulmona se fumaneha karolong e hlahang ea kutu ea pulmona ho tloha ventricle e nepahetseng. Thuto ea pulmona e na le mali ho tsoa pelong ho ea matšoafong. Ka holimo ho likheo tsa liphahlo tsa methapo ea pulmonary ke lithapo tse nyenyane tse tletse mali le ho thibela ho khomarela liphahlo ho lerako la pulmone ha phaseha e buloa. Nakong ea systole ea atria, mali a phalla ka mahlaseli a bulehileng le a metral ho li-ventricles. Nakong ea systole ea ventricles, ho eketseha ka tšohanyetso khatellong ho lebisa ho koaloa ha liphahlo tsa atrioventricular. Sena se sitisa ho khutlela mali ho atria. Maqhubu a li-valve a tšoaroa ka likhama, tse sa ba lumelle hore li bule ka lebaka la khatello ea li-ventricles. Kamora ho koaloa ha li-valve tsa atrioventricular, mali a phalla ka li-valve tsa semilunar ho ea ho kutu ea pulmonary le aorta. Li-valves tsa semilunar li buloa ka lebaka la khatello e matla li-ventricles le ho oa haufinyane ha systemole e fela mme diastole e qala.
Ketsahalo ea Pelo
U sebelisa phonendoscope, u ka utloa hore pelo e 'ngoe le e' ngoe e tsamaea le ponahalo ea lipina tse peli tsa pelo. Mohala oa pele o hlaha nakong ea ho koaloa ha li-valve tsa atrioventricular, 'me oa bobeli - nakong ea ho koala valve ea methapo ea pulmonary ea valve ea aortic. Litsuoa li tloha likarolong tse ka tlase le liphahlo tsa li-valve tsa tricuspid le mitral, ebe li tsamaisoa ka tlase 'me li khomaretsoe ke mesifa ea papilla e kenang ka har'a mongobo oa ventricular.
Molao-motheo oa ho sebetsana le likhahla
Methati e thibela ho kenngoa ha liphahlo tsa li-valve tsa atrioventricular moeeng oa maqeba tlas'a liketso tsa khatello e phahameng ea mali nakong ea motlakase oa ventricular. Li khomaretse li-valves tse haufi, tse tiisang hore li koaletsoe ka thata nakong ea ventricular systemole le ho thibela ho phalla ha mali ho khutlela ho atrium. Sephara sa aortic le valve ea methapo ea methapo e boetse e bitsoa semilunar. Li fumaneha tseleng ea ho tsoa ka mali ho tsoa pelong le ho thibela ho khutlela ha mali ho li-ventricle nakong ea diastole. E 'ngoe le e' ngoe ea li-valve tsena tse peli e na le halofo ea khoeli e bōpehileng joaloka makhasi. Li na le lihlahisoa tse sebetsang 'me li koahetsoe ke endothelium. Endothelium e etsa hore li-valve li boreleli.
