====Ascending aorta====
{{Main|Ascending aorta}}
The [[ascending aorta]] begins at the opening of the [[aortic valve]] in the left ventricle of the heart. It runs through a common [[pericardium|pericardial sheath]] with the [[pulmonary trunk]]. These two blood vessels twist around each other, causing the aorta to start out [[posterior (anatomy)|posterior]] to the pulmonary trunk, but end by twisting to its right and [[anterior]] side.<ref name="Gray's Anatomy for Students">{{cite book|last1=Drake|first1=Richard L.|last2=Vogl|first2=Wayn A.|last3=Mitchell|first3=Adam W.

The transition from ascending aorta to aortic arch is at the pericardial reflection on the aorta.<ref name="Netter">{{cite book|last=Netter|first=Frank H.|title=Atlas of Human Anatomy|url=https://archive.org/details/atlasofhumananat00nett_0|url-access=registration|edition=3rd|year=2003|publisher=ICON Learning Systems|isbn=978-1-929007-21-9}}</ref>{{rp|Plate 211}}

At the root of the ascending aorta, the [[lumen (anatomy)|lumen]] has  small pockets between the [[cusps of heart valves|cusps]] of the [[aortic valve]] and the wall of the aorta, which are called the [[aortic sinus]]es or the sinuses of Valsalva. The left aortic sinus contains the origin of the [[left coronary artery]] and the right aortic sinus likewise gives rise to the [[right coronary artery]]. Together, these two arteries supply the heart. The [[posterior (anatomy)|posterior]] aortic sinus does not give rise to a coronary artery. For this reason the left, right and posterior aortic sinuses are also called left-coronary, right-coronary and non-coronary sinuses.<ref name="Gray's Anatomy for Students"/>{{rp|191}}
