Anatomy study note · Thorax

Right ventricle

The chamber that pumps blood through the pulmonary valve into the pulmonary trunk. It forms most of the sternocostal surface and the inferior border of the heart.

Key points

• Inflow: tricuspid valve; outflow: infundibulum → pulmonary valve.
• Moderator band carries the right bundle branch.
• Crescentic cavity; thinner wall than the left ventricle.
• Mainly supplied by the right coronary artery.
• Ventricles: primitive ventricle + conus, partitioned.
• Purkinje fibres: large pale conducting cells.
• Endocardium / myocardium / epicardium.
