Grades 9-12 Performance Task

Contributed by: Oregon State Department of Education

Homeostasis is the mechanism that maintains balance in body systems. An example of this is the cardiovascular system, in which levels in the cells. Carbon dioxide levels are monitored by the hypothalamus and results in changes of pulse rate to optimize gas exchange from the lungs to the cells. In this investigation, students examine this feedback mechanism monitored by the brain and how the normal pulse rate is affected by a stressor, exercise.
