Document Summary
Chapter 19 - the urinary system: fluid and electrolyte balance. Solute and water content of plasma is affected by movement of materials in and out of the body and by movement of materials between body compartments. Ways in which materials can be gained or lost from plasma: exchange with extracellular connective tissue including bone (ca & p, by exchange with cells. Outside exchanges: exchange with materials in the lumen of the gi tract, exchange with materials in the lumen of the kidney tubules, loss through sweating, hemorrhaging and respiration. The transport of materials across the wall of the gi tract normally involves a net gain of water and solutes. The transport of materials across the walls of the renal tubules amounts to a net loss of water and solutes by the body. Balance occurs when solutes and water enter and leave the plasma at the same rate.
