Question

the structure that Guards the left auricle ventriculo aperture

Answer 1

The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, between the right atriumand the right ventricle. The function of the valve is to prevent back flow of blood from the right ventricle into the right atrium.
