Tricuspid valve Chordae tendineae
Papillary muscles
Tricuspid complex
Conus arteriosus
Supraventricular crest Trabeculae carneae
Septomarginal trabecula
The right atrioventricular orifice and valve The orifice and valve of the pulmonary artery
• Opening during systole, with cusps pressed toward wall of vessel as blood is forced upward
• Closed during diastole
– Ventricular pressure drops in diastole
– Floating together of valve cusps, with free borders meeting, thus closing the valve
