Nearby galaxies are some of the best laboratories to understand the physical processes that drive galaxy evolution. I will present spatially-resolved far-infrared spectroscopic observations in these systems obtained with Herschel (KINGFISH, Beyond the Peak, and HS3MC) and followup programs from SOFIA. I will discuss the use of several FIR indicators as measures of star formation rate, volume density, column density, and ISM pressure. I will compare these measurements to theoretical predictions to understand better the multiphase structure of the interstellar medium in galaxies, its relation to star formation activity, and the prospects for future missions and instruments.
