Cardiovascular System OverviewCardiovascular System Overview
• A “closed” system consisting of the heart and blood vessels.
– Arteries – carry blood away from the heart
– Veins carry blood towards the heart
• Systemic circuit – delivers oxygenated blood to the body tissues and back
• Pulmonary circuit – delivers deoxygenated blood to the lungs and back
