What Is the Cardiovascular System?
The cardiovascular system, also called the circulatory system, is the body’s network of the heart and blood vessels that transports blood throughout the body. It delivers oxygen, nutrients, hormones, and immune cells to tissues while carrying away carbon dioxide and waste products.
A healthy cardiovascular system is essential for every organ to function properly.
Why the Cardiovascular System Matters
The cardiovascular system supplies the body with the oxygen and nutrients needed for normal function. Problems affecting the heart or blood vessels can reduce blood flow and increase the risk of serious health conditions such as heart attack, stroke, and heart failure.
