It passes the blood to the right ventricle of the heart through the tricuspid valve, which has three cusps or leaflets, and is also known as the right atrioventricular valve. • The main anatomical features of the right atrium include the sinus venarum, which surrounds the openings of the superior and inferior vena cavae as well as the coronary sinus, which in turn are also major structures. The atrial walls are made up of pectinate muscles which form a pouch known as the right auricle. The crista terminalis separates the cardiac and smooth muscle layers of the atrial walls, while the interatrial septum divides the atria. • 0:17 Functions of the right atrium • 0:52 Anatomy of the right atrium • 1:32 Pectinate muscles • Want to test your knowledge on right atrium?
