Qhov thib ob lub plawv suab (S2) tshwm sim nrog kaw ntawm lub semilunar li qub . Feem ntau qhib ntawm semilunar li qub yog nyob ntsiag to, tab sis nyob hauv aortic lossis pulmonic stenosis, thiab lub moos tawm yuav hnov. tshwm sim thaum ntxov hauv systole thaum pib tshem tawm vim tias nws tshwm sim los ntawm kev qhib lub semilunar li qub.
Yooj yim li ntawd, lub suab twg hauv qab no cuam tshuam nrog kev kaw ntawm Semilunar li qub?
Lub plawv Suab yog txuam nrog nrog Valve Kaw Peb hnov cov no vibrations raws li ob qhov sib txawv suab ; lub-dub. Thawj zaug suab , "lub", is txuam nrog nrog lub kaw ntawm AV li qub . Qhov thib ob suab "dub", yog txuam nrog nrog lub kaw ntawm lub semilunar li qub.
Qhov thib ob, lub aortic Semilunar valve suab li cas? Lub plawv thib ob suab , los yog S.2, tsim cov "dub" ntawm "lub-dub" thiab suav nrog cov khoom A2 ( aortic lub cev kaw) thiab P.2 ( ntsws ntsws kaw). Nws yog tshwm sim los ntawm kev kaw lub semilunar li qub (cov aortic lub cev thiab ntsws ntsws ) qhov kawg ntawm ventricular systole thiab pib ntawm ventricular diastole.
Tsis tas li ntawd, dab tsi ua rau Semilunar li qub qhib thaum lub plawv dhia?
Cov semilunar li qub qhib thaum cov leeg nqaij ua haujlwm sib cog lus thiab tsim cov ntshav siab nyob hauv lub ventricle siab dua li tsob ntoo hlab ntshav. Thaum lub plawv mob so lub sijhawm diastole pib dua.
Dab tsi li qub raug kaw thaum thawj lub suab nrov?
Thawj lub suab suab muaj zog me ntsis ntau dua li lub suab thib ob. Thawj lub plawv suab yog tsim los ntawm kev kaw ntawm lub mitral thiab tricuspid valve siv cov ntawv me me Lub suab lub plawv thib ob yog tsim los ntawm kev kaw ntawm daim ntawv aortic thiab pulmonic valve.

Lub semilunar li qub yog flaps ntawm endocardium thiab cov ntaub so ntswg txuas ntxiv los ntawm cov fibers uas tiv thaiv cov li qub los ntawm kev tig sab hauv. Lawv zoo li lub hli ib nrab, yog li lub npe semilunar (semi-, -lunar). Pulmonary Valve: Lub plawv valve no nyob nruab nrab ntawm txoj cai ventricle thiab pulmonary artery
