TRUE
The atrio-ventricular valves (or A-V valves) are exactly what their name implies. They are valves located between the atria and ventricles. Since there are two atria and two ventricles, it follows naturally that there must be two A-V valves. The one on the right is called the TRICUSPID valve and the one on the left is called the MITRAL valve.
Between the Atria and Ventricles of the heart are the aptly named Atrioventricular valves. The valve between the right atrium and ventricle is called the Tricuspid because id has three Cusps (of small flaps the are pushed together and closed when under pressure). The valve between the left atrium and ventricle is called the Bicuspid because it has two cusps, of more often called the Mitral Valve because its two cusps look like a bishops hat.
ventricles
Arteries carry blood away from the heart.
If I am not wrong the lower two chambers of the heart are called as ventricles i.e. left ventricle and right ventricle while the upper two chambers of the heart are called as atria( plural of atrium) i.e. left atrium and right atrium.
The valve between your RIGHT atrium and ventricle is called the TRICUSPID VALVUE and the valve between your LEFT atrium and ventricle is called the MITRAL or BICUSPID VALVUE.

The fascia
The top of the heart is called the apex. The left and right ventricles are located in the apex of the heart.
The ventricles of the heart are most commonly known; there are ventricles in the brain, however.

Two lateral ventricles, third ventricles and the forth ventricles produce the cerebrospinal fluid.
