A working model of a human lung or a bell jar model can be used to demonstrate the breathing mechanism. These models typically include a pump to mimic the diaphragm movement, balloons or rubber sheets to represent the lungs, and tubes to simulate the airways. By manipulating these components, one can illustrate how the process of inhalation and exhalation occurs in the human respiratory system.
A lung model is important in studying the respiratory system as it helps researchers and students visualize the structure and function of the lungs. It can be used to demonstrate how air flows in and out of the lungs, the exchange of gases, and the mechanics of breathing. Lung models provide a hands-on learning experience that enhances understanding of respiratory processes.
Meselson and Stahl used heavy isotopes of nitrogen (N^15 and N^14) to track the replication of DNA in E. coli bacteria. By switching from N^15 to N^14, they were able to demonstrate the semi-conservative mechanism of DNA replication.

No, the esophagus is not used for breathing. It is the tube that connects the throat to the stomach and is responsible for transporting food and liquids to the stomach. Breathing occurs through the trachea and the lungs.
It is the diaphragm.
The model lung with balloons can be used to demonstrate how the diaphragm and rib muscles work together to expand and contract the lungs, mimicking the process of inhaling and exhaling. As the balloons inflate and deflate, it shows how the lungs fill with air when we breathe in and release air when we breathe out. This hands-on demonstration helps visualize the mechanics of breathing in a simple and interactive way.
The Heinrich model is used to demonstrate the importance of safe acts and conditions. It is used in investigations and is often criticized for being biased and leading investigators to only look at the act, and not what provoked a person to behave they way he or she did.

Air is used for breathing. Breathing is used to introduce oxygen into our system. Oxygen is necessary for life. Without breathing in air we would die.
A breathing barrier device should be used if providing rescue breathing to minimize the risk of disease transmission.
