Two.

First the blood is pumped up through the pulmonary arteries into the lungs, where capillaries transfer the blood to the pulmonary veins.

The pulmonary veins bring the blood into the left aorta, which pumps to the left ventricle and into the aorta. From the aorta, the blood hits coronary arteries, which drain into capillaries to supply the heart itself. The right atrium picks up blood via the coronary veins which pick that blood up from the capilllary bed in the coronary sinus.

Two: one in the side trip to the lungs and one in the body destination.
