Cardiovascular System Quiz: How Well You Know? Trivia - Quiz

How well do you know the cardiovascular system? The cardiovascular system transports all kinds of materials, such as carbon dioxide, hormones, and blood cells, to and from the body's tissues to give it nutrients, the ability to fight off certain diseases, stabilize temperature and pH and maintain homeostasis. The cardiovascular system can also be described as the circulatory system. This quiz will help you to build a solid knowledge base of the cardiovascular system.
