Chemicals responsible for the dilation and increased permeability of blood vessels in the inflammatory response are called:

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

fe 55.85 g/mol and h2o 18.02 g/mol.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
