Humans for Organs: Introduction: On June 26‚ 2000‚ scientists involved in the Human Genome Project announced their success in mapping the human genome. This has created an enormous controversy over property rights in human tissue. With advances in biotechnology and the advent in cloning‚ it seems likely that these issues will continue to cause controversy in the years to come. As the shortage of organs available for transplantation continues to grow‚ new methods of obtaining organs and tissues

This system consists of several organs such as the trachea‚ lungs‚ larynx‚ pharynx‚ etc. All of these organs work together to help us breathe and are formed to their function. There is two different ways of respiration; external respiration which is the exchange of gases between the alveoli and the blood‚ and internal respiration which is the exchange of gases between the blood and tissue cells.
