TASK: Follow the instructions to create a clay heart like this one ALSO include the pulmonary and mitral valves.
You will need:
playdoh or clay (3 or 4 colors)
a small bit of paper or plastic
pencil
other possible tools for design (small paintbrush, water, small knife for crafts)
If you are not able to purchase some clay, then please draw and label the heart.
General Steps to build the basic model based on the image above.
Mold the material into the proper shape (roughly pear-shaped) and size (for an accurate model, the heart is about the same size as a fist). Make sure the middle is mostly hollow or make a heart cross-section that is flat.
Mold the structures of the heart.
In the middle show the atria and ventricles.
Use ridges to show the septums that divide the heart’s chambers and create openings for the valves. You can roll up small amounts of clay to make a ridge. Poke a hole with a pencil to make openings.
Place two small flaps (of plastic or paper) over each of the valves. Attach one end of the flap to the septum and leave the other unattached. The two flaps should meet at the middle when closed.
Add the veins and arteries to the heart. Make sure all are in the correct locations and that the blood vessels have open entries into the central heart.
Make labels for the parts listed below.
Take a photo of your completed heart and upload it to the assignment. Here is my heart without the labels
