Students are gathering evidence to demonstrate that body systems work together. They measure the number of breaths per minute of five adults during three different activities: at rest, after jogging for thirty seconds, and after jogging for one minute.
They plot the average results on a graph, as shown.
The students claim that several body systems work together; therefore, these body systems change a person’s breathing rate depending on the level of activity.
Using complete sentences, identify three body systems that work together to change a person’s breathing rate depending on the level of activity. Be sure to include the role that each body system plays in the process.
