Cardiovascular System Allows Humans to Survive. It

Cardiovascular system allows humans to survive. It is an essential component to the very complicated machinery that guides the functioning of the human body. It is this reason that has led to numerous research projects in order to discover news ways of making the heart function better. By improving the heart, the remainder of the body will be able to better operate. It was with this exact purpose that research teams were able to come up with a way to regenerate cardiac muscle cells in order to reprogram the heart into making new cells and repairing itself. As explained in Scientific American (2012), the heart already has the capacity of regenerating itself, however, the regeneration process is an extremely low one, and is tremendously limited. The actual study conducted by Eulalio et al. (2012) and published in Nature (2012) provides the proof necessary to support the idea of cardiac cell regeneration and how the exact mechanisms could be sped up in order to have a better success rate.

The regeneration of cardiac cells is essential to the prevention of further heart disease and eventual failure. As explained in both Scientific American (2012) and Eulalio et al. (2012), heart cells are only able to regenerate at a limited and slow pace. The speed of this regeneration is increased when a heart attack occurs, but only by a minute percentage. According to this knowledge, the researchers, Eulalio et al. (2012) wanted to figure out a way in which the speed of the process could be amplified in order to essentially heal the entire heart at a higher rate and with more precision. One of these ways is to reprogram the genetic process, more specifically, the microRNAs, in order to stimulate the regeneration process. Since heart failure is one of the main causes of natural fatalities in the world, this research has opened up the opportunity for a potential cure to diseases of the cardiovascular system.

The magazine, Scientific American, a secondary source, presents the information about a study that was conducted by researchers at the International Centre for Genetic Engineering and Biotechnology. The information is presented in an easy to understand format. The topics are broken down and categorized systematically in order to facilitate the understanding of the information. Because Scientific American is meant for average readers, the article does not contain any difficult-to-understand words, nor does it encompass a complete explanation of how the physiology of the cardiovascular system works. Instead, the information is easy to understand and is explained enough to grasp onto the main ideas. Details are scarce and the names of all the scientists involved in the projects have been omitted. The secondary source is also presented in a more opinionated format. There are quotes from reactions of the individuals who are both involved and/or excited about the scientific findings. The pictures shown are also very vague and are presented as aesthetic appeal instead of for informative purposes.
