Water is key to life. Humans can survive more than a month without food, but only a few days without water. Water is found inside and outside cells and circulates in the blood.
Compare and contrast facilitated diffusion and active transport with respect to their mechanisms, the type of material being moved, and the energy source for their movement. Define osmosis and explain how it differs from simple diffusion across membranes. Compare and contrast osmolarity and tonicity of solutions.
Body fluids can be discussed in terms of their specific fluid compartment, a location that is largely separate from another compartment by some form of a physical barrier. The intracellular fluid (ICF) compartment is the system that includes all fluid enclosed in cells by their plasma membranes.

Sep 21, 2019 · This document discusses various mechanisms of membrane transport including passive diffusion, facilitated diffusion, active transport, filtration, and endocytosis. It describes passive diffusion as a bidirectional process that moves molecules down a concentration gradient without requiring energy.
