Every 40 seconds, someone in the United States has a heart attack (Heart Disease and Stroke Statistics 2017). Students may experience or be affected by several incidences of heart attacks throughout their life. As such, students should be aware of the risk factors and learn the underlying reasons for a heart attack. Most students believe they are too young for a heart attack and think symptoms will appear gradually (Roth and Gotter 2018). Heart disease in younger individuals is appearing more frequently due to obesity, tobacco and alcohol usage, stress, and race (Napoli 2019). In this article, the authors describe how blood flow is important to the cardiovascular system by considering the harmful effects of smoking on the body using the Hewson and Hewson Learning Cycle Instructional Strategy (Keeley and Konicek-Moran 2015).
