Blood leaves via right ventricle without oxygen, goes to lungs, fills up with oxygen and returns to heart through the left atrium. It then moves into the left ventricle and goes to the body to deliver oxygen.
But as the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise. Hope this helps
