The goal of this problem-based module is to explore the effects of health-related issues (e.g., obesity, arteriosclerosis) on pressures in the circulatory system. Modeling and engineering design are key practices comprising the Next Generation Science Standards, making these modules timely and well-suited for life science classrooms at the introductory college level. These STEM modules bridge standard-based biology, physics, and health concepts in an integrative approach to learn fluid dynamics and physiology in authentic situations. Physiological issues represented include: (1) plaque formation and effect on flow, (2) elastic recoil and arteriosclerosis, (3) effects of blood viscosity on flow, and (4) differential blood pressure related to resistance. Exercises guide learners in assembling and using human circulatory system models to explore principles of pressures as they related to tubing, flow, and resistance. Findings from the investigations are used to construct diagnoses and recommended treatments for patients in realistic scenarios with a secondary emphasis on a healthy lifestyle.
