Change in blood flow rate and WSS-induced vasoreactivity.
| hCCA | hBA | rCrA | ||||
| Initial | Final | Initial | Final | Initial | Final | |
| flow rate (mL s–1) | 4.82 | 8.3 | 0.4 | 1.22 | 2.67 × 10–6 | 2.78 × 10–6 |
| diameter (cm) | 0.639 | 0.675 | 0.267 | 0.277 | 2.17 × 10–3 | 9.78 × 10–3 |
| WSR (s–1) | 188 | 275 | 214 | 583 | 2,658 | 3,879 |
| WSS (dyn cm–2) | 7 | 10 | 7 | 20 | 53 | 78 |
| Viscosity (Poise) | 0.035 | 0.035 | 0.035 | 0.035 | 0.02 | 0.02 |

Experimental data obtained in human common coronary artery (hCCA) (Carter et al., 2016), human brachial artery (hBA) (Joannides et al., 1995), and rat cremaster muscle arterioles (rCrA) (Koller and Kaley, 1991). WSR, wall shear rate; WSS, wall shear stress. Data in italics are calculated from the experimental data given by the authors using Eq. 7. The sensitivity coefficient SWSS is defined as the ratio of change in diameter on change in WSS between initial and final conditions.
