These are the 3 different types of circulation. Not sure if it matters which box you put them in or what..? Don't quite get that chart. But luckily I had a similar question on one of my old assignments. Don't know if you needed definitions but here you go,
Pulmonary circulation: This part of the cycle carries oxygen-depleted blood away from the heart, to the lungs, and back to the heart.
Systemic circulation: This is the part that carries oxygenated blood away from the heart and to other parts of the body.
Coronary circulation: This type of circulation provides the heart with oxygenated blood so it can function properly
