Question

Write the function of valves present in between atria and ventricles

Answer 1

The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. The valves prevent the backward flow of blood.

Answer 2

The ‘main function’ of the valves present between the atria and the ventricles is to prevent the ‘back flow of blood’ from one ‘chamber of the heart’ to the other.  

The heart consists of ‘4 chambers’, ‘2 atria’, and ‘2 ventricles’. The valves that are present in-between they are,

1. Atrioventricular (AV) valves

2. Mitral valve (‘bicuspid valve’)

3. ‘Tricuspid valve’, which are between the “upper chambers (atria)” and the “lower chambers (ventricles)”.  

The ‘semilunar (SL) valves’, the ‘aortic valve’ and the ‘pulmonary valve’, which are in the ‘arteries leaving the heart’.
