Cardiovascular System What is it?
The cardiovascular system consists of blood, blood vessels, and the heart.
It carries nutrients, hormones, gases, and cellular wastes throughout the body.
This system is the body's delivery system transporting oxygen and nutrients to every part of the body.
It also picks up the carbon dioxide and other waste products Main Parts
