TABLE 1.
The characteristics of different rat arteries stretched to an internal circumference of 0.9*IC100: values of inner diameter, passive tension and corresponding levels of transmural pressure calculated according to Laplace’s law.

| Saphenous (7) | 600 ± 49 | 1.88 ± 0.16 | 52 ± 3 |
| Sural (8) | 272 ± 30 | 0.90 ± 0.15 | 55 ± 9 |
| Interlobar renal (6) | 412 ± 54 | 1.18 ± 0.22 | 48 ± 5 |
| Septal coronary (8) | 290 ± 34 | 0.71 ± 0.11 | 41 ± 8 |
| Basilar (7) | 358 ± 35 | 0.82 ± 0.14 | 38 ± 6 |
The numbers in parentheses are the number of animals in the group. Data are presented as mean ± SD.
