The cardio means heart, and vascular means veins and arteries. Essentially, the cardiovascular system is the path of blood cells through the body, from and to the heart. This term is synonymous with the circulatory system.
Blood travels through veins and arteries throughout the body in order to provide necessary gasses (i.e. O2) to our muscles, and to pick up certain gasses (i.e. CO2) from those muscles. Via veins, CO2 is delivered to the lungs, where the blood cells exchange CO2 with O2. The O2-filled blood is then pumped out of the heart and is then delivered to muscles via arteries.
Let us look at the termology. Cardio means heart and vascular is the arteries and veins. Functions would be heart which is a pump . Pumping blood out into the body through the veins and it is retruned to heart through the arteries. It a circulatory system for the body.
