The heart is a very powerful muscle located in the left side of the chest. The heart is responsible for pumping blood to all of the parts of the body, providing them with oxygen and nutrients necessary to function. Creating a visual model of the heart is a helpful tool in understanding the anatomy of the human heart. Making a visual model accurately may take some time, but in the end is an excellent means of learning about this vital organ.

  1. 1

    Look at the detailed image of the human heart and shape the right and left ventricals and the right and left atria of the heart. Place them on the piece of cardboard, using it as a base for the model.

  2. 2

    Cut the plastic tubing into sections for the pulmonary artery and the aorta. The tubing for the aorta should then be placed into the proper section of the clay for the right atria. The tubing for the pulmonary artery should be placed correctly into the left ventrical portion of the clay.

  3. 3

    Refer to the image of the heart and paint the sections of the heart and the tubing accordingly. Sections that are red signify blood containing oxgen, and the blue sections signify blood lacking oxygen.

  4. 4

    Label the sections of the heart "right atrium, left atrium, right ventricle, left ventricle, aorta and pulmonary artery" on the paper using the black pen. Cut the labels out and pin them to the corresponding sections.

Tips and warnings

  • Coloured clay or playdough can also be used for the sections of the heart (instead of using paint), the coloured clay or playdough can then be moulded around the tubing also.
  • It is best to make the heart true to size for a better understanding of the organ.
  • If drinking straws are more handy than tubing, they can be used as the aorta and pulmonary artery.
  • Use caution when handling scissors and pins, as they are sharp.
