The Wiggers diagram showing simultaneous events of the cardiac cycle in composite graphs is one of the most intimidating figures students encounter in their study of physiology. This paper describes a discovery learning activity that walks students through the construction of the Wiggers diagram by focusing on the core concepts of blood flow down pressure gradients and the structure-function.. What is the Wiggers Diagram? The Wiggers Diagram is a classic graph in physiology that represents all the events of the cardiac cycle in one picture.
