Cardiovascular means “about the heart and the blood vessels” — the tubes that carry blood around the body. Doctors use it constantly in cardiovascular disease, which is not one illness but a family of problems in that system (a heart attack, a stroke, and others). You also meet it in fitness: cardiovascular exercise makes the heart and lungs work harder, like running or swimming; gym people it to . Though actually, the tidy meaning is always heart-plus-vessels, not heart alone. It is a medical and sports-science word, not a word for chatting about feelings.
心血管的（心血管疾病極常用；講運動時台灣也說有氧、心肺）
組成From cardio- + vascular. cardio- is “heart” (from Greek kardía); vascular is “about vessels,” from Latin for a small vessel.
