1-2) is important because parallel vessels decrease total vascular resistance.

When there is a parallel arrangement of resistances, the reciprocal of the

**total**
**resistance** is equal to the sum of the reciprocals of the individual resistances. For

example, the

**total resistance** (RT) of three parallel resistances (R1,R2, R) would

be: 1 1 1 1 R. R. " R. " R, or solving for Rr, Eq. 5-7 R1 = --- R. "R," R, Two

important principles emerge from Equation 5-7. First, the

**total resistance** of a

network of parallel ...
