The superior end of the right ventricle that tapers to a smooth-walled pouch and ends at the pulmonary valve is called the conus arteriosus. The auricle is an ear-shaped pouch attached to the upper part of the atria. The aortic sinus is a bulge in the ascending aorta. The ligamentum arteriosum is a fibrous band that connects the aorta and the pulmonary trunk. The fossa ovalis is a depression in the interatrial septum.
