The term "cardiovascular" refers to anything related to the heart and blood vessels. The cardiovascular system is responsible for circulating blood throughout the body, delivering oxygen and nutrients to tissues while removing waste products. A healthy cardiovascular system is essential for overall well-being, as it helps maintain proper organ function and supports physical activity. Common issues related to the cardiovascular system include heart disease, hypertension, and stroke. These conditions can arise from factors like poor diet, lack of exercise, and smoking. Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can significantly reduce the risk of cardiovascular problems.
