The case of “The Sole Remaining Supplier” deliberates between what is more important‚ a human beings life or financial loss. During the year 1975‚ doctors across the nation started to implant a new and promising medical technology called pacemakers. It was in its early years; therefore‚ cardiology doctors did not possess the advanced skills needed to install such equipment. A patient’s heartbeat depended solely on these units to survive; however‚ a malfunction from such unit would cause a patient

Replacing Animal Testing: Unrealistic The issue of whether or not animal experimentation should be used for research in medicine and science has been debated for years. After conducting research on both sides of the issue‚ I have found that we should not replace animal testing with alternative methods at the present time. The proposal to replace animal testing in medical science is somewhat unrealistic and would prove to be disadvantageous. There are four substantial reasons for this: animal research

Scenario The heart pacemaker is a modern wonder. The device has a timer that resets itself every time the patient’s heart beats. If the heart does not beat on schedule (say‚ within 1.2 seconds)‚ the pacemaker gives a stimulus that causes a heartbeat. You are on the board of directors of a company that makes transistors. Among the many companies with whom you have a contract is one that makes heart pacemakers. Pacemaker technology is in its infancy. When doctors implant a pacemaker‚ the patient’s normal

On the anterior surface of the heart the inter-ventricular septum is marked by a shallow groove called the anterior inter-ventricular sulcus‚ which holds adipose tissue‚ the great cardiac vein and the anterior inter-ventricular artery.

The myocardium (cardiac muscle)‚ is the thickest section of the heart wall and contains cardiomyocytes‚ the contractile cell of the heart. 2. What part of the heart is the pacemaker and why? The SA Node is located in the right atrium of the heart. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium‚ at the center of the heart and near the entrance of the

Since the beginning of time there have always been those that have opposed exploration of uncharted lands. This statement holds truth also for the NASA program since the beginning when President John F. Kennedy’s vision was to land a man on the moon by the end of the decade.’ Instead of all the opposition of NASA and questions such as‚ "Why should we go to space?" I believe people should ask themselves‚ "Why shouldn’t we go to space?" Christopher Columbus didn’t have to sail over the Atlantic Ocean

Animal Testing: Should Animals be used in Research? Animal testing is the use of living animals for scientific or commercial testing. According to my first source‚ an article found on animalresearch.thehastingscenter.org‚ called Animals Used in Research in the U.S.‚ in 2010‚ there were about 26 million animals being used for research. Mice‚ rats‚ fish and birds are the most common animals used; they are about 96% of the 26 million animals used. Other animals used in research that year were Guinea
