The cardiovascular system, also known as the circulatory system, is made up of the heart, blood, and blood vessels. It provides blood to the body and supplies organs with oxygen and nutrients. The cardiovascular system works by pumping blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body.
