Objective 67: Contrast volume and electrolyte content in inter- and extracellular fluid compartments

With the help of some excellent diagrams, this objective was a breeze. Did I stress that diagrams are extremely helpful in learning a majority of these concepts? I obtained these photos and slides from the PowerPoint lecture outlines available for our class and included them. Although, I did refer to my textbook for some more information and that helped out a great deal. The first photo that I've included can be found in chapter 25 page 868 and the fourth photo can be found in chapter 25 page 869. The first photo breaks down the major fluid compartments of the body, and it is plain to see that intracellular fluid makes up the majority of it. That makes sense, cells need fluids to perform their functions. Extracellular fluid is composed of two things, interstitial fluid and plasma. ICF is 25 L of our bodies total water, while ECF is only 15 L of our bodies total water (40 L all together). The last chart is very helpful because it shows the total solute concentration that each electrolyte occupies in ICF, ECF, and blood plasma.
