Coronary circulation is…

the dedicated network of blood vessels that supplies oxygenated blood to the heart muscle (myocardium) and removes deoxygenated blood

Pulmonary circulation…

the vital network of blood vessels that carries oxygen-depleted blood from the heart to the lungs to pick up oxygen, and returns the oxygen-rich blood (back to the heart)

Systemic circulation…

the network of blood vessels that carries oxygen-rich blood from the left side of the heart to the (rest of the body)
