- The heart circulates blood through two pathways: the pulmonary circuit and the systemic circuit.
- In the systemic circuit, oxygenated blood leaves the body via the left ventricle to the aorta.
- In the pulmonary circuit, deoxygenated blood leaves the right ventricle of the heart via the pulmonary artery and travels to the lungs.
- Deoxygenated blood returns via veins to the venae cavae, re-entering the heart's right atrium.
- Blockage of any of these arteries can cause a heart attack.
