Sense: adjective/1
Cardiovascular is the broadest of these related terms, covering both the heart (cardio-) and blood vessels (vascular). Cardiac refers exclusively to the heart — a cardiac arrest is a heart stoppage, not a blood vessel problem. Vascular relates only to the blood vessels — a vascular surgeon operates on arteries and veins but not the heart itself. Circulatory describes the whole blood-flow process, emphasising movement rather than anatomy. Aerobic has a narrower scope: it describes exercise that uses oxygen, which happens to strengthen the cardiovascular system, but the term itself is about the type of activity, not the body parts. For example: 'Regular aerobic exercise improves cardiovascular health' uses both words naturally — aerobic describes the exercise mode and cardiovascular names the system being strengthened.

Etymology
Combines cardio- (from Greek kardia, meaning 'heart') with vascular (from Latin vasculum, meaning 'small vessel'). The word entered medical English in the late 1800s as doctors began to understand the heart and blood vessels as a connected system.
