Final answer:
The term 'cardio' refers to the heart, while 'vascular' means pertaining to the blood vessels. Together they make up the cardiovascular system, which is essential for blood circulation, and a target for various diseases often linked to atherosclerosis.
Step-by-step explanation:
The terms 'cardio' and 'vascular' refer to different aspects of the circulatory system. 'Cardio' pertains to the heart, which is the central organ responsible for pumping blood throughout the body. 'Vascular' relates to the blood vessels, which are the network of arteries, veins, and capillaries through which blood flows. Together, the cardiovascular system is crucial for maintaining the flow of blood, which carries oxygen and nutrients to body tissues and removes waste products. Cardio exercises, like biking, running, or swimming, are designed to increase the heart rate and improve cardiovascular health. Cardiovascular diseases (CVDs) include a range of conditions like coronary artery diseases, strokes, and peripheral artery disease, often linked to atherosclerosis, which is the build-up of plaques in the artery walls.
