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. ==Additional images== <gallery> Image:Gray490.png|Front view of heart and lungs. </gallery> ==External links== * {{GPnotebook|-254803911}} * {{eMedicineDictionary|Conus+arteriosus}} {{circulatory-stub}} {{Gray's}} {{Heart}} [[it:Cono arterioso]]
