Cov ntsws ntsws muaj sab laug, sab xis, thiab sab xub ntiag. Cov aortic valve muaj sab laug, txoj cai, thiab nraub qaum cusps. Cov tricuspid valve siv muaj anterior, posterior, thiab septal cusps; thiab mitral valve tsuas muaj anterior thiab posterior cusps. a) Tricuspid valve , nyob nruab nrab txoj cai atrium thiab txoj cai ventricle.

Hauv qhov no, lub ntsws Semilunar valve txawv li cas ntawm tricuspid valve?

Li qub ntawm lub plawv Txoj cai atrioventricular valve yog tricuspid valve siv . Sab laug atrioventricular valve yog bicuspid, lossis mitral, valve . Cov valve nruab nrab ntawm txoj cai ventricle thiab mob ntsws lub cev yog pulmonary semilunar valve . Cov valve nruab nrab ntawm sab laug ventricle thiab aorta yog aortic semilunar valve.

Tsis tas li ntawd, vim li cas lub mitral valve txawv ntawm peb lub plawv li qub? Mitral Valve Cov ntawv nthuav tawm qhib kom cov ntshav txav mus tom ntej los ntawm plawv thaum ib nrab ntawm lub plawv dhia. Lawv kaw kom cov ntshav ntws rov qab thaum lub sijhawm lwm yam ib nrab ntawm lub plawv dhia. Cov mitral valve cov muaj tsuas yog ob daim ntawv; aortic, pulmonic thiab tricuspid li qub muaj peb.

Yog li, puas yog lub ntsws ntsws tricuspid?

Lub plawv muaj plaub li qub uas tswj cov ntshav khiav mus rau lub plawv: aortic, mitral, tricuspid thiab pulmonic (tseem hu ua mob ntsws ) li qub . Cov tricuspid valve siv nyob nruab nrab ntawm sab xis atrium thiab sab xis ventricle. Cov pulmonic valve yog nyob nruab nrab ntawm txoj cai ventricle thiab lub mob ntsws cov hlab ntsha.

Lub hom phiaj ntawm cov li qub hauv lub siab yog dab tsi?

Cov plawv muaj plaub chav, ob lub atria (chav sab saud) thiab ob lub ventricles (chav qis). Muaj ib valve los ntawm cov ntshav hla ua ntej tawm hauv txhua chav ntawm plawv . Cov li qub tiv thaiv cov ntshav khiav rov qab.
