CARDIOVASCULAR HEALTH

LESSON #3 Hand In

THE CARDIOVASCULAR SYSTEM:

The heart, lungs and blood vessels all work together as a unit!

1. _?_ refers to the heart. Vascular refers to the system of blood vessels.

2. These vessels can be either veins (bring de-oxygenated blood back to the heart) or artery’s (bring oxygenated blood from the heart to the muscles and organs).

3. Deoxygenated blood enters the heart in the right atrium. Next it is pumped into the right ventricle. Blood then travels to the lungs to pick up oxygen before it returns to the left heart to be pumped out to the body.

4. Where is your heart and how big is it? Size of the clenched fist and is in the left side of your chest

LABEL THE HEART:

Left Atrium: holds oxygenated blood from the lungs.

Left Ventricle: pumps oxygenated blood throughout the body.

Right Atrium: holds deoxygenated blood that has returned from the body.

Right Ventricle: pumps deoxygenated blood to the lungs.

Aorta: the largest artery in the body – transports oxygenated blood from the heart to the body.

Septum: the thick wall that divides the heart into two separate sides.
