CC; Creating Coronary

The coronary arteries have a very complex structure and are lying around the myocard of the hearth. The coronary arteries can be split into two parts: the right coronary artery and the left coronary artery. They both begin in the aortic sinuses respectively the left and right aortic sinuses. The middle aortic sinus doesn’t have a connection with a coronary artery.

The right coronary artery is follows the border between the right atrium and right ventricle in the sulci of the hearth. When the sulci is reaching the interventricular septum of the hearth the sulci and the right coronary artery is turning and follows his way on the interventricular septum as the posterior interventricular branch of the right coronary artery.

The left coronary artery splits into two veins: the Circumflex branch of left coronary artery and the anterior interventricular branch. The Circumflex follows the border of the left atrium and the left ventricle in the sulci of the heart. The end of the Circumflex is near the spot were the posterior interventricular branch of right coronary artery at the interventricular septum.

The anterior interventricular branch is following the sulci on the interventricular septum of the hearth. The interventricular branch ends near the end of the posterior interventricular branch of right coronary artery.

These 3 veins are the main veins of the hearth. They split up in multiple branches that are going into the myocard to muscles of the heart of blood. For the printed model it is only necessary to visualize these tree veins, because it is very heart to see which way the branches are following.
