  1. Megan did her project on the flow of blood into an out of the heart. She chose to do her project as a PowerPoint slideshow. She begins with a nice title screen letting us know exactly what she chose to do her project on. She begins her explanation stating that blood enters the heart in the right atrium from two different veins. One from the upper half of the body and one from the lower half. The blood is then pushed form the right atrium into the right ventricle through the tricuspid valve and then pushed out of the heart to the lungs. After being oxygenated in the lungs, the blood returns to the heart and enters the left atrium before being pushed into the left atrium. The left atrium pushes the blood into the left ventricle and then exits the heart through the aortic valve. After exiting the heart, the oxygenated blood is sent to the entire body before returning back to the heart to start again. Throughout the power point, Megan does a good job of using illustrations and drawings to show exactly what is happening at each stage of the heart beating. While power point is short and does not contain a lot of information, it does a very good job of describing exactly what happens every time the heart beats. I think a useful addition to the power point would be a slide containing information on how much blood is in the body and even things like how many times per minute the heart beats.
