Many biological tissues have layers with different extracellular matrix components and different orientations of these components. As a result, diffusion coefficients vary from region to region. Even within a region, the diffusion coefficient depends on the direction of transport, a situation know as anisotropy. Consider the steady-state, one-dimensional diffusion of a molecule across an artery wall consist of an acellular phase and a cellular phase. There are no chemical reactions. An example of such a tissue is an elastic artery that contains a layer of smooth muscle cells of thickness L1 and an elastic lamina of thickness L2. (Actually, an artery consists of repeating layers of elastin and smooth muscle cells, but for the present discussion, consider a single layer of each.) The molecule diffusion coefficients of the two layers are Di, 1 and Di, 2 respectively. The concentration of the molecule at the lumen surface (x = 0) is C0, and the concentration at x = L1 + L2 = L is CL.
L1 =…
Nutrient media is flowing at a rate of 1.5 L min in a tube that is 5 mm in diameter. The walls of the tube are covered with antibody-producing cells, and these cells are
anchored to the tube wall by their interaction with a special coating material that was applied to the surface of the tube. If one of these cells has a surface area of 500
um², what is the amount of force that each cell must resist as a result of the flow of this fluid in the tube? Assume the viscosity of the nutrient media is 1.2 cP=0.0012 Pa

- Water has many unique molecular properties that make it extremely important. One application that takes advantage of these properties is a so-called evaporative cooler (or swamp cooler, https://en.wikipedia.org/wiki/ Evaporative_cooler), which is a device that cools air through the evaporation of water. Liquid water is changed into water vapor, whereby the energy used to evaporate the water (i.e. latent heat of vaporization) is consumed from the internal energy (i.e. temperature) of the air brought in from outside. The result is a lowering of the outside air temperature as it is brought inside. The process tends to also increase the humidity (vapor content) of the air. Hence it is an attractive option in some semi-arid regions where outside air is very hot and dry. a) What is the latent heat of vaporization for water? Is this value generally large or small compared to other substances? What are some of the implications of this? b) Suppose you have an evaporative cooler that has an…arrow_forwardQuestion: Sunflower is 2 m long and diameter of the xylems (capillary tubes of plants carrying water from root to top) are 500 micrometer.
