Nyob rau hauv ib txwm muaj, lub plawv valve tiv thaiv regurgitation ntawm deoxygenated ntshav los ntawm cov hlab ntsha pulmonary rov qab mus rau sab xis ventricle. Nws yog semilunar valve nrog 3 cusps, thiab nws nyob rau sab xub ntiag, superior, thiab me ntsis rau sab laug ntawm lub aortic valve.
Dab tsi yog txoj haujlwm ntawm lub tshuab nqus tsev pa?
Pulmonary Valve (los yog Pulmonic Valve)
qhib kom tso ntshav los ntawm txoj hlab ntshav mus rau lub ntsws (los ntawm cov hlab ntsha pulmonary) qhov twg nws yuav txais oxygen. Tiv thaiv cov ntshav rov qab los ntawm cov hlab ntsha pulmonary mus rau sab xis ventricle.
Sab laug pulmonic valve ua dab tsi?
Lub pulmonic valve yog ib qho ntawm ob lub li qub uas tso ntshav tawm hauv plawv ntawm cov hlab ntsha. Nws yog ib txoj kev valve, txhais tau hais tias cov ntshav tsis tuaj yeem rov qab mus rau hauv lub plawv los ntawm nws.
Yuav ua li cas thaum lub pulmonary valve qhib?
Thaum sab laug ventricle cog lus, lub ventricle sab xis kuj cog lus. Qhov no ua rau pulmonary valve qhib thiab tricuspid valve kaw. Cov ntshav ntws tawm ntawm sab xis ventricle mus rau lub ntsws ua ntej nws rov qab mus rau sab laug atrium li cov ntshav tshiab, oxygenated.
Pulmonary valve tswj dab tsi?
Lub pulmonary valve tswj ntshav ntws los ntawm txoj hlab ntaws mus rau hauv cov hlab ntsha pulmonary, uas nqa ntshav mus rau koj lub ntsws kom khaws cov pa. Lub mitral valve cia cov ntshav uas muaj oxygen los ntawm koj lub ntsws hla ntawm sab laug atrium mus rau sab laug ventricle.
