Where is your heart located?
Many people think their heart is located on the left side of their chest. It is actually located almost in the center of the chest, between the lungs. It’s tipped slightly so that part of it sticks out and taps against the left side of
the chest, which is what makes it seem as though it is located there.

Your heart is one hard working muscle!
The force you use to squeeze a
tennis ball is about the same amount of force your heart uses to pump blood
out to the body. Even at rest, the muscles of the
heart work hard- twice as hard as the leg muscles
of a person sprinting.
