Figure 8: Simplified representation of the cortical microvascular path, intravascular oxygenation and supplied tissue territories.

From: Large arteriolar component of oxygen delivery implies a safe margin of oxygen supply to cerebral tissue

Figure 8

A vertical cross-section through the cortical tissue revealing one microvascular path close to the cortical surface including pial arteriole (PA), diving arteriole (DA), precapillary arteriole (PCA), capillary path (C1–C6) with the low-branching-order capillaries (C1–C3) and high-branching-order capillaries (C4–C6), postcapillary venule (PCV), surfacing venule (SV) and pial venule (PV). Arrows represent the direction of the blood flow. Vascular segment colours represent approximate average segment SO2. Tissue territories supplied by capillary segments are outlined in yellow.
