Solution

In humans, Heart has four chambers, in which two are left and right atria. These thin walled structures function as uninterrupted transferring of blood into ventricles. The right atrium carries deoxygenated blood and left atrium carries oxygenated blood.

The two of four chambers of human’s heart, are ventricles. These are thick walled structures. Right ventricle transfers impure blood to lungs while left ventricle transfers blood to body.

The tricuspid valve is made of three cusps and works for prevention of blood flow back to right atrium from right ventricle. The valve also called as right atrioventricular valve and present in right dorsal side.

Mitral valve or bicuspid valve is made of two cusps and prevents the back flow of blood from left ventricle to left atrium.

The pulmonary valve is a semilunar valve and made of three cups. This lies in between pulmonary artery and right ventricle, in addition it prevents the back flow of impure blood to right ventricle.

The aortic valve is generally made of two cusps and finds in between left ventricle and aorta. It prevents the back flow of pure blood into ventricle.

Chordate tendinae are strings like tendons find in both ventricles for connecting papillary muscles to both type of valves individually.
