Left coronary artery

Branch out of the aorta in the coronary sulcus. On the left side of the heart. After it goes behind the pulmonary trunk, it splits into two. One branch goes down in the anterior aspect of the heart between the ventricles. The other branch goes around in a circle giving rise to the circumflex artery

Anterior interventricular artery

One branch of the left coronary artery gives rise to the anterior interventricular artery. Runs parallel to the great cardiac vein.

Circumflex Artery

One branch of the left coronary artery goes around in a circle giving rise to the circumflex artery.

Right Coronary artery

Branch out of the aorta in the coronary sulcus. On the right side of the heart. When it reaches the posterior aspect of the heart, it will give rise to the posterior interventricular artery

• Posterior interventricular artery

Between the ventricles in the posterior aspect of the heart. The Right Coronary artery gives rise to the posterior interventricular artery. Runs parallel to the middle cardiac vein

Great cardiac vein

Anterior aspect of the heart. Runs parallel to the anterior interventricular artery. Dumps deoxygenated blood into the coronary sinus.

Small cardiac vein

Little heart model has the small cardiac vein very small but it goes all the way down. Dumps deoxygenated blood into the coronary sinus.

Middle cardiac vein

Posterior aspect of the heart. Runs parallel to the posterior interventricular artery. Dumps deoxygenated blood into the coronary sinus

Coronary sinus

All these veins dump the blood into the coronary sinus. Is in the coronary sulcus between the atrium and ventricle. It receives deoxygenated blood. Inside the right atrium, you see the opening of the coronary sinus. It dumps the blood into the right atrium.

Pulmonary trunk

Blue trunk next to the aorta. The right ventricle pumps blood into the pulmonary trunk. It is split into the pulmonary arteries.

Pulmonary arteries

Split from the pulmonary trunk. They do carry deoxygenated blood within them. They take the used up blood to the lungs to become oxygenated.

Pulmonary veins

Blood goes from the lungs back to the heart through the pulmonary veins. It carries oxygenated blood
