Simple squamous epithelium
A hydrophobic molecules (such as a steroid molecule) can easily diffuse into the cell
epithelial tissue, connective tissue
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
That material would be included in the category of electrical "insulators".

Oxygen (O2)
Wood An insulator is a material that does not allow charges to move through it easily.

capillaries are the site of exchange of materials where the needed substances in the tissue diffuse into them from the capillary through diffusion.while the metabolic wa ste from tissues diffuse into the capillary and taken away.the capillaries have a big surface area and their cells is one cell thick to enable diffusion to take place fast.
metal
Capillaries. they have such thin walls that substances can easily diffuse through them.
Conductor.
Metal
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
epithelial tissue, connective tissue
Materials that allow energy to flow easily through it are called conductors.
