Anterior (frontal) view of the opened heart. White arrows indicate normal blood flow.
Right heart is a term used to refer collectively to the right atrium and right ventricle of the heart; occasionally, this term is intended to reference the right atrium, right ventricle, and the pulmonary trunk collectively.
The right atrium receives deoxygenated systemic blood from the superior and inferior vena cavae. The blood is then pumped through the tricuspid valve into the right ventricle, which in turn pumps the blood through the pulmonary valve into the pulmonary artery.

Anatomy of torso, cardiovascular system: heart |
| atria (interatrial septum, musculi pectinati) • ventricles (interventricular septum, trabeculae carneae, chordae tendinae, papillary muscle) • valves
base • apex • grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) • surfaces (sternocostal, diaphragmatic) • borders (right, left)
right heart
(vena cavae, coronary sinus) → right atrium (auricle, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of the inferior vena cava, valve of the coronary sinus) → tricuspid valve → right ventricle (conus arteriosus, moderator band/septomarginal trabecula) → pulmonic valve → (pulmonary artery and pulmonary circulation)
left heart
(pulmonary veins) → left atrium (auricle) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)
pericardium (sinus) • epicardium • myocardium • endocardium • cardiac skeleton (fibrous trigone, fibrous rings)
conduction system
cardiac pacemaker • SA node • AV node• bundle of His • Purkinje fibers
