Fluid Pressure Gradient (10 pts) A section of avascular tissue is composed of cells, the extracellular matrix, and the interstitial fluid. Assuming that the diameters of the cells and the fibers are 5 m and 0.1 m, respectively, the fiber length per unit volume is 10 7 /mm 2 , the number of cells per unit volume is 10 6 /mm 3 , and the interstitial gradient of fluid pressure (G = dp/dx) is 20 mmHg/mm, calculate the following:

A. The porosity of the tissue . = +

B. The hydraulic conductivity of the tissue using the Kozeny-Carman equation below where is the diameter of the cells only. = 2 180 2 (1) 2
