1. How many chambers does the heart have? _______________
4

2. Turn on Show labels. What are the names of the chambers? _______________________,
right atrium
aC s

left atrium
_______________________,
rightventricle left ventricle
_______________________, _______________________
3. Do you see tiny “doors” that open and close as blood is pumped through the heart? ______
yes
ed d
ar stu
These are heart valves. Heart valves control the flow of blood through the heart.
4. Click Heartbeat sound and listen for the two parts of the heartbeat, nicknamed “lub” and
is
“dub.” Observe the heart. (Note: The recording is not in sync with the heart animation.)
Th
What do you think causes heartbeat sounds?
the closingof the valves
In fact, the “lub” sound is caused by valves from the atria to the ventricles closing, and the
sh
“dub” sound is caused by the valves from the ventricles to the blood vessels closing.
5. Challenge: Why do you think the left atrium and left ventricle are shown on the right side of
They the left side of thebody
