Read the Popular Science article - How Doctors Reinvented the Human Heart and prepare a short account of how doctors designed the device. Make an appointment to discuss the article with me.
 * ‍4. The Future of Medicine - The No Pulse Heart **

I found the article very interesting on how doctors are using these devices to improve lives of patients with heart disease.I found it interesting in the beginning of the article how the calf lived with a motor-type heart and when the doctors removed his real heart the calf managed to live and thrive. The bit about how the first artificial heart, the Jarvik-7, allowed a person to live for 112 days before the balloons and other parts of the Jarvik-7 wore out from preforming the work of the heart. The article also mentions how Cohn used metal spoons with slots cut into them in order to hold the heart during the transplant, and how Cohn uses rare earth magnets to move catheters throughout out the body without making incisions into the patient. The other interesting part of the article is how Frazier had to watch a heart surgeon preform heart surgery and Frazier had to reach into the patients heart and pump it by hand in order to keep the patient alive. The most interesting part of the article was on how the Central American man and a woman from New York had a LVADs installed that kept them alive and allowing them to go on throughout their life without their hearts working. The design of the pump is also interesting as it uses a electromagnet in the blades of the screw instead of a axle, the screws were made bigger to turn evenly, and new bearings were placed to prevent blood clots.

 * Fetal Pig Dissection -**


 * 5. Changing the Eating Habits of a Nation- **

I think that the William D. Kelley School is doing a good thing by trying to fight obesity in school kids try to better the health of the students. Offering the students a free and healthy breakfast as an alternative to buying snacks at the corner stores around the area of the school is good idea in the right direction. Another step in the direction is the organization called Food Trust trying to get corner store owners to sell healthier snacks for kids even though only a few store owners signed onto the plan. Although the school and the city of Philadelphia as a whole try to improve the health of the children I think there are other things the city can do to help the children. Although the school tries to offer kids healthier food options I think that the school should try to offer the students ways to exercise to help them keep in shape and burn off their fat. Although the school has parents walk around the neighborhood and try to discourage kids from buying unhealthy snacks and discourage store owners from selling unhealthy snacks to kids I think a better plan would be to gather parents and teach them about proper nutrition and try to educate people more about a proper diet and exercise as well. I also believe the school should get away from the opinion of Marion Nestle, who believes that regulation and force will help the children become healthier. I don't believe that the school should try and force the kids away from the corner stores but instead they should educate the kids of the dangers of these unhealthy foods. You cannot just force children and their parents to change their diets by force but instead try to teach them and get them to realize themselves what they are purchasing is unhealthy and that only they can help themselves not force them into changing themselves.
