dc.description The microcirculation in rat spinotrapezius muscle and muscle fascia is investigated using a computational approach. The simulations are based on a realistic microvascular network structure obtained from microscope observations and consider both blood rheology and vessel elasticity. An improved model for the apparent viscosity of blood is developed to take the shear thinning nature of blood into account. Capillary bundles of muscle tissue are composed of vessels that mainly follow the direction of muscle fibers. In muscle fascia, however, the capillary vessels form a mesh like network without a preferred direction. This structural difference leads to significant differences in the microcirculation. In the muscle fascia, vessel length, velocity, and shear rate follow a lognormal distribution. In muscle, however, the data does not support a lognormal distribution. For both networks, the hematocrit follows an approximately normal distribution. -
