Fig. 7.

Partial pressure of O₂ (pO₂) depth profiles of descending arterioles under baseline (n = 9 vessels) and occlusion (n = 5 vessels) conditions across all animals. Symbols represent unique arterioles over 8 animals. “Early” branching is noted as occurring at z ≤ 150 µm, while “latent” occurring after this depth. See Media 7 ^{(41.6KB, PDF)} for repeated baseline measurements in two arterioles.
