atrioventricular valves- tricuspid valve present in between right atrium and ventricle. Bicuspid or Mitral valve is present in between left atrium and left ventricle. semilunar vales - pulmonary valve guards opening of pulmonary valve, aortic opening is guarded by aortic valve

2. Valves of heart-
There are four valves of the heart, which are divided into two
categories:
•Atrioventricular valves: The tricuspid valve and mitral (bicuspid) valve.
They are located between the atria and corresponding ventricle.
•Semilunar valves: The pulmonary valve and aortic valve. They are
located between the ventricles and their corresponding vessel, and
regulate the flow of blood leaving the heart.

4. Atrioventricular valves-
Mitral and tricuspid valves are supported by the attachment of
chordae tendineae which are attached to papillary muscles,
papillary muscles are attached to internal walls of ventricle
these papillary muscles contracts during systole to prevent prolapse
of valve leaflets into atria
Closure of these valve produces first heart sound ‘LUB’

5. Semilunar Valve-
Located at the openings of outflowing vessels.
They close at the beginning of ventricular diastole. The closure of these valves
produces 2nd heart sound ‘DUB’
The leaflets of valve are attached to the walls of blood vessel, dilated portion is
called as sinus, superior edge of leaflet is called as lunule, nodule is present at
center of lunule
1) pulmonary valve- located in between infundibulum of right ventricle and
pulmonary trunk. The valve consist of 3 cusps
2) Aortic valve- located in between left ventricle and opening of ascending
aorta.
Aortic valve is made up of 3 cusps- right, left, posterior

7. Clinical anatomy of valve-
Stenosis- stiffness of valves
Stenosis of mitral valve
Stenosis of aortic valve
Tricuspid valve stenosis
Pulmonary valve stenosis
