Contraction cycle characteristics of lymphangion 1. Representative graphs of the average intralymphatic pressure, diameter, and P–V loop of lymphangion 1. Some significant points throughout this contraction cycle were chosen to showcase some significant points throughout its contraction cycle. These points (A–G) represent the start of systole (point A), the peak intralymphatic pressure (point B), the end of systole (point C), the start of rapid filling of the lymphangion 1 (point D), the onset of downstream lymphangion (lymphangion 2) relaxation (point E), the end of the rapid filling phase (point F), and finally the end of the contraction cycle (point G)
