Reflection
Throughout this project, I learned many things about the human body that I didn't already know. For example, I learned that the periosteum is the outside layer of the bone. I also learned that the heart has two lower chambers, the ventricles, and two upper chambers, the atriums. I also learned that the sides are switched on the heart, meaning that the left atrium is on the right side of the heart. I enjoyed learning about all the systems in the body, however, I found that the major organs in the excretory and the digestive systems were very easy to confuse. |
