The cardiovascular system includes the heart, blood, and blood vessels. It circulates oxygen, nutrients, hormones, and immune cells while carrying away carbon dioxide and other waste.
This information is educational and is not intended to diagnose medical conditions. Symptoms can have many causes, and persistent or concerning symptoms should be evaluated by a qualified healthcare professional.
Primary Functions
