In 2011, we published a description of 15 core concepts of physiology, and in 2017 we described how core concepts could be used to teach physiology. On the basis of publications and conference presentations, it is clear that the core concepts, conceptual frameworks, and the homeostasis concept inventory have been used by faculty in many ways to improve and assess student learning and align instruction and programs. A growing number of colleagues focus their teaching on physiology core concepts, and some core concepts have been used as explicit themes or organizing principles in physiology or anatomy and physiology textbooks. The core concepts published in 2011 were derived from inputs from a diverse group of physiology instructors and articulated what this group of instructors expressed a decade ago. On the basis of current feedback from the physiology teaching community as a consequence of the use of core concepts in teaching and learning, we have revisited these concepts and made revisions to address issues that have emerged. In this article, we offer revised definitions and explanations of the core concepts, propose an additional core concept ("physical properties of matter" which combines two previous concepts), and describe three broad categories for the revised core concepts. Finally, we catalog published resources for each of the core concepts that provide instructors tools to focus facilitation of student learning on goals (learning outcomes), activities and assessments to enable students to develop and apply their understanding of the core concepts of physiology.
