Function of the heart

I can describe what the human heart is and what it does.

Lesson details

Key learning points

  1. The heart is a hollow, muscular organ located behind the breastbone and slightly to the left of your chest.
  2. The average heart is approximately the size of a human fist and some say its shape is similar to an upside down pear.
  3. The function of the heart is to pump blood to all parts of your body.
  4. Your heart will beat around 115,000 times each day.
  5. Models can be used to help us to learn about the human heart.

Common misconception

Children often think that the function of the heart is to make or clean blood. Also that the heart is 'love heart' shaped.

The model making in this lesson helps children to think about which objects and materials they can use to represent the heart and demonstrate how it pumps blood around the body.

Keywords

  • Organ - An organ is a part of the body that does a particular job, such as the brain, heart and lungs.

  • Function - The function of an organ is its job within the body.

  • Heart - The heart is an organ that pumps blood around the body.

  • Blood - Blood is pumped around the body by the heart.

  • Model - A model is used to describe something that cannot be experienced directly.

Making a model of a human heart should be simple at this stage of education. Encourage children to model dough to the correct size and shape of a human heart rather than worrying about identifying and naming individual chambers of the heart.
