The '''conus arteriosus''' is a conical pouch formed from the upper and left angle of the [[right ventricle]], from which the [[pulmonary artery]] arises.
A tendinous band, which may be named the ''tendon of the conus arteriosus'', extends upward from the [[Fibrous rings of heart|right atrioventricular fibrous ring]] and connects the posterior surface of the conus arteriosus to the [[aorta]]. This is also called the infundibulum, and it is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk. The wall of the infundibulum is smooth.
