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 relationship of heart valves and one-way blood flow through the heart. Additional tasks require students to transfer their understanding to previously unstudied scenarios and figures, such as the left ventricular pressure-volume loop.

威格氏图以复合图的形式显示了心动周期的同时发生，是学生在学习生理学过程中最令人望而生畏的图形之一。本文描述了一项发现式学习活动，该活动通过关注血流沿压力梯度下降的核心概念以及心脏瓣膜的结构-功能关系和单向血流通过心脏，引导学生构建威格氏图。其他任务要求学生将他们的理解转移到以前未研究过的场景和图形，如左心室压力-容积环。威格氏图是学生在学习生理学过程中最令人望而生畏的图形之一。本文描述了一项发现式学习活动，该活动通过关注血流沿压力梯度下降的核心概念以及心脏瓣膜的结构-功能关系和单向血流通过心脏，引导学生构建威格氏图。
