PSL 250 is a non-prerequisite, non-majors, yet very intensive course that thoroughly covers the fundamental mechanisms and processes of human physiology. The underlying physiology of the entire human body will be covered in this course. Aside from discussing the systems of the human body by exploring their functionality at all levels of their organization (i.e., molecular, cellular, tissue and organ), the overlying theme of this course will be that of systems integration. We will first study how individual organ systems work as stand-alone, functional units. As the semester progresses, we will integrate our understanding of these systems so to build a picture of the organism level of organization (i.e., you).
