The cardiovascular system transports blood to and from the heart to all tissues of the body. Its main function is to transport oxygen and carbon dioxide, nutrients, and metabolic waste products. It is also involved in temperature regulation, hormone distribution, and immune function.
The cardiovascular system is composed of the following structures:
Heart – pumps blood through the system
Arteries – vessels that deliver blood to tissues
Capillaries – networks of small vessels that perfuse tissues
Veins – vessels that return blood to the heart
Blood vessels are found in all tissues of the body with very few exceptions, such as epithelia and cartilage.
