The word 'cardiovascular' refers to things that are related to the heart and blood vessels in your body. For example, when you exercise, you are doing cardiovascular activity because your heart is working harder and your blood is flowing faster. Doctors often use this word to describe problems with the heart and blood vessels, such as high blood pressure or heart disease. It's important to know this word if you want to talk about your health or if you need to understand medical information about the heart and circulatory system.
