The cardiovascular system refers to the heart and blood vessels that pump and transport blood throughout the body. The heart serves as the pump, while the blood vessels (arteries, veins, and capillaries) make up the circulatory system that carries oxygen, nutrients, and hormones to the body’s cells and removes waste products. The cardiovascular system is responsible for maintaining proper blood flow, oxygen delivery, and waste removal, and is essential for overall health and well-being. Abnormalities or diseases of the cardiovascular system, such as hypertension, heart attacks, and strokes, can lead to serious health problems and can be life-threatening. Treatment for cardiovascular disease may involve lifestyle changes, medication, and medical procedures.
