🏗️ Levels of Organisation — Cell → Tissue → Organ → System

Painted progression showing the four levels of biological organisation as increasing-scale vignettes: a single muscle cell, then muscle tissue (many cells together), then a whole heart organ, then the cardiovascular organ system within a human torso. Each scale level is shown in a circular painted vignette connected by sepia flow arrows.

Figure 1: Levels of biological organisation — cells form tissues, tissues form organs, organs form systems.
