Document Summary
This lecture will focus primarily on fluid imbalances rather than the mechanisms of maintaining fluid balance that you studied last year in anatomy and physiology. The presentation will help you to link physiology and pathophysiology to clinical situations to what you might assess and to what interventions might be appropriate. To understand fluid and electrolyte imbalances, you need to know how the body regulates fluid balance: renal physiology, the basics of fluid balance, and the basics of electrolytes in body fluids. It"s important that you remember your anatomy and physiology. Diffusion, osmosis and active transport (from the link above) Fluids and solutes move continually throughout the body in order to maintain homeostasis. Membranes that separate the intracellular, interstitial and intravascular compartments are semipermeable. Some, but not all, solutes are able to pass through these membranes. Three forms of cellular movement are shown below. Passivetransport of solutes across cell membranes from an area of higher concentration to one of lower concentration.
