FIG 3. Vessel diameters of nontreated swine retia (controls).

A, Schematic of a rete with section lines demarcating sectors for vessel measurements (AP, ascending pharyngeal artery; CCA, common carotid artery).

B, Graph shows the corresponding vessel diameters in each region for a 35-kg (diamonds) and 100-kg (squares) swine. Error bars indicate the standard error of mean.
