Appendix
The Georgia Standards that are used in the framework of this unit are:
S7L2: Students will describe the structure and functions of cells, tissues, organs, and organ systems.
a. Explain that cells take in nutrients in order to grow and divide and to make needed materials.
b. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions.
c. Explain that cells are organized into tissues, tissues into organs, organs into systems, and systems into organisms.
d. Explain that tissues, organs, and organ systems serve the needs cells have for oxygen, food, and waste removal.
e. Explain the purpose of major organ systems in the human body.
Acknowledgement
I would like to thank the teamwork achieved during the 2011 Yale National Initiative between myself and Eric Laurenson of the Pittsburgh Teachers Institute. Together we combined efforts in designing and creating a working model of a pumping heart which was invaluable to the overall understanding of the function of the heart and as a result gives me the ability to make a working heart to use as a demonstration for the students in the classroom. This project was also designed to produce a working vascular tree with bifurcations going from a large diameter hose of 5/8" representing the Aorta to a ¼" tube representing capillaries with the other sizes being ½", and 5/16" thus replicating the arterial and venous system of the vascular system as a demonstration of the pressure drop that occurs from the aorta to the capillary bed.
