Welcome to our study with Apologia’s Human Anatomy and Physiology. This week we’ve been studying the circulatory system.
My daughter’s science study this year has taken a new twist in that she is studying science at a co-op once a week, as well as at home through out the week. That gives her the opportunity for new experiences and different perspectives on studying anatomy and physiology.
The circulatory system project this week in co-op came right out of the Apologia Human Anatomy and Physiology text book. Using graham crackers, different sized marshmallows and colored icing a model heart was created. The blue icing represents the de-oxygenated blood coming back from the body and the red icing represents the oxygen rich blood from the lungs ready to be pumped back to the body.
At home, my daughter decided she wanted to do another heart model to make sure she knew the proper flow of blood through the heart. Hands-on projects are always great to improve understanding. She decided to make this one more life-like. Using her ipod, she found a cross-section drawing of a heart showing the flow of blood. She used the sculpting clay she uses in her art and jewelry projects to make her own.
Other heart models to try:
- When learning the difference between arteries and veins, always remember that Arteries carried the oxygen-rich blood Away from the heart and both Arteries and Away begin with the letter A.
- Veins always carry de-oxygenated blood to the heart, except for the pulmonary veins which carry oxygen rich blood from the lungs to the heart muscle itself.
