3. Your heart is an organ made mostly of cardiac muscle tissue
2. The Heart
Your heart is an organ made mostly of cardiac muscle tissue
The lub-dub, lub-dub noise of a beating heart is the sound of the valves opening and closing

4. Valves are located between the atrium and ventricle
2. The Heart
2 sides (left & right)
Atrium (upper chamber)
Ventricle (lower chamber)
Valves are located between the atrium and ventricle

6. How blood travels through your body
3. Blood Vessel Network
How blood travels through your body
3 types of blood vessels

7. 1. Arteries – carry blood away from the heart to the organs
3. Blood Vessel Network
1. Arteries – carry blood away from the heart to the organs
2. Veins – carry blood back to the heart
3. Capillaries – tiny, allows exchange between blood and cells in other tissue

8. Cardiovascular and The Respiratory System
Your heart pumps blood to the lungs
In the lungs, carbon dioxide leaves the blood and oxygen enters to blood
From here, the blood travels back to the heart and distributes the oxygen- rich blood to the rest of the body

10. Blood Circulation – Due tomorrow!
Color the flow of blood according to the image on Mrs. Stephens website.
Label:
Left and right ventricle
Left and right atrium
Veins (2)
Arteries (2)
Capillaries (3)
3. On the back of your diagram, describe what is happening at each step during circulation. There are a total of 5 steps
If you are finished then you can read or work on other HW
