The cardiovascular system consists of the heart, blood, and coronary arteries, which work together to transport oxygen and nutrients throughout the body.
Step-by-step explanation:
BoldThe cardiovascular system is composed of multiple organs and components, including the heart, blood, and coronary arteries. It is responsible for the circulation of blood and oxygen throughout the body. The heart pumps oxygenated blood to the body's tissues, while the blood carries nutrients, oxygen, and waste products. The coronary arteries supply oxygen-rich blood to the heart muscle itself.
