Basic knowledge of the Heart, where it is, what it looks like, nerves and how the heart functions, the heart beats, and the role in survival is something every child not only needs to know but is curious about. In "HARTY THE PUMP" the character called HARTY explains all of this and much more to two inquisitive children.

HARTY explains to children:

• How blood is carried in blood vessels
• How many blood vessels there are
• The different types of blood vessels
• What pulse means
• How pulse changes with heart rate
• Why heart beats faster at times
