Schematic illustrating the spatial distribution of each type of cell (i.e. agent) in the ABM.

<p>The bottom right schematic represents a luminal and artery wall patch where N is the number of leukocyte agents residing in this luminal patch. Among all leukocytes (N), M is the number that adheres to the endothelial cell surface area (A). V is the patch volume and h is 100μm or the distance between the patch centroids. All these parameters are used to find leukocyte adhesion probability (see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005523#pcbi.1005523.e018" target="_blank">Eq 2</a>).
