Atria or Atrium
Auricles
Ventricles
Interatrial Septum
Interventricular septum
Atrioventricular Orifice
Heart Chambers and Valves
• Atrioventricular Valve (A-V valve)
• Sulci
• Atrioventricular (coronary) Sulcus
• Interventricular Sulci
• Tricuspid Valve
• Chordae Tendineae
• Papillary Muscles
Heart Chambers and Valves
• Pulmonary Trunk
• Pulmonary Arteries
• Pulmonary Valve (pulmonary semilunar
valve)
• Pulmonary Veins
• Bicuspid Valve (mitral valve)
• Aorta
• Aortic Valve (aortic semilunar valve)
Skeleton of the Heart
• Fibrous rings with other masses of dense
connective tissue found in part of the
septum between the ventricles that make
the skeleton of the heart.
• Provide firm attachments for the heart
valves
• Prevents the outlets of the atria and
ventricles from dilating during contraction.

Blood Supply to the Heart
• Aorta
– Coronary Arteries
• Left coronary arteries
– Circumflex artery
– Anterior interventricular artery (left anterior descending
artery)
• Right coronary arteries
– Posterior interventricular artery
– Marginal artery
