Renal iii, integration of salt and water homeostasis: body water and electrolyte compartments. Icfv-intracellular fluid volume, ecfv- extracellular fluid volume, ecv- effective circulating volume. Kidney"s role= adequate blood flow to all organs at all times: relationships between icfv(intracellular fluid volume), ecf (osm), and ecf (na) Intracelluar fluid volume is dependent on extracellular fluid osmololity. (know this. Sodium concentration- sodium is the main electrolyte by content of the extracellular fluid: disturbances and regulation of water and salt intake. Diluting the urine- need to get rid of water. When sleeping - you dont consume much water - you actually lose water - the osmolality was changing as you sleep - kidney adjust according to those changes. Respiratory system is a circadian rhythm (not necessarily day to day) Circ-annual rhythm- whales in the pacific heading north. Systole to diastole - this is a rhythm of cardiovascular system. Our patterns of urination follow a rhythm -this follows the exact cycle:
