An Overview of the Cardiovascular System

What the cardiovascular system is and how it works.

Your cardiovascular system is one of the most important systems in your body. The cardiovascular system is made up of your heart, your blood vessels and your blood.

I’m Heart Healthy Henry and I’m going to be taking you on a tour of your cardiovascular system, telling you how it works and what you need to do in order to take care of it.

An Overview of the Cardiovascular System

Your cardiovascular system manages the blood by moving it from the heart to the other parts of the body. This blood moves oxygen and nutrients to everywhere your body needs it. On the way back from the different parts of your body, the blood picks up waste so your body can rid itself of it.

The Heart

The heart is like the motor of your cardiovascular system. About the size of a fist, the heart is a muscle that expands and contracts in order to pump blood through it and the entire body via the blood vessels.

Your Blood Vessels

Blood vessels are the largest part of your cardiovascular system. Your blood travels to the parts of your body through your blood vessels. Your blood vessels include arteries, arterioles, capillaries, venules, and veins.

Each blood vessel has an important role to play. For example, the blood vessels that carry the blood away from your heart are called arteries and the smaller blood vessels that drain blood back to the heart are called veins.

Did You Know: The heart of an adult pumps approximately 4,000 gallons of blood daily!

Taking Care of Yourself

While the cardiovascular system is a large and complex part of your body, without it you wouldn’t be able to live. Because of this, it’s important to take care of yourself and your cardiovascular system.

If you want to take proper care of your cardiovascular system, you need to eat right and exercise properly. Stick to a diet that’s high in fruits and vegetables and limit your intake of cholesterol and fats as well as sodium. Doing this will keep the walls of your blood vessels clear and your cardiovascular system running in tip-top shape.
