In this article I will defend the use of organs-on-chips in medical research as well as the use of humans as subjects for biomedical testing research. My thesis is based on the idea that human testing and organs-on-chips have the potential to improve the field of medical research by reducing the time needed to achieve results in the fight against diseases, epidemics and pandemics. First, I will illustrate the shortcomings of animal testing and describe how organs-on-a-chip work. I will then explain why the use of organs-on-chips can produce accurate and timely results that could reduce the impact of epidemics. Next, I will describe some benefits of human experimentation. Finally, I will identify the flaws of organs-on-chips and elaborate on the negative issues surrounding human experimentation by analyzing the Tuskegee study. Traditionally, animal testing has been an important component of biomedical research. It has been a very important tool for modern medical scientists, researchers and epidemiologists studying diseases to find effective remedies. The discovery of treatments for various infectious, airborne, communicable, and chronic diseases can be attributed to animal experimentation. However, there are several fundamental issues that undermine the perceived success of animal testing in biomedical research. Such issues include the following: the time-consuming nature of animal testing, the scientific limitations of animal testing, the reliability of animal testing results, the high economic costs, and the ethical concerns associated with animal testing. The animal testing process involves several phases. In the first phase, animals are given a single dose of a compound to be tested. This stage is known as…half of the paper…that have been discovered so far may not have been found. While animal testing and organs-on-a-chip both have advantages and disadvantages, the advantages of organ-on-a-chip far outweigh its shortcomings. The opposite is true for animal testing, as its flaws far outweigh its benefits. When the organ-on-a-chip is compared to animal testing as a tool for medical research, it turns out that the organ-on-a-chip has the potential to produce faster and more accurate results than animal testing. While animal testing has led researchers to effective treatments for diseases in the past; organ-on-a-chip allows researchers to unlock treatment for many more diseases at a lower financial cost. Animal testing has a proven track record; but organs-on-chips have the potential to become a more powerful tool for biomedical researchers of the future.
