Vital Capacity of Lungs

This week in science we further explored the systems of the human body. We learned about the respiratory system and how the lungs are important for the exchange of oxygen to our red blood cells and the exchange of the waste product C02 from the blood. The connection between the circulatory system and respiratory system was focused on. In this week's lab, students measured their lung capacity to further understand how a larger person requires a larger set of lungs so that more oxygen and carbon dioxide exchanges can take place simply due to the person having more cells in his or her body. Not surprising, the larger students in class had larger lung capacity and those smaller students had less lung capacity. Students involved math by finding the average of three of their exhales.
