lungs causing pulmonary edema. (Cadwallader pp. 1141 - 1142). Right-sided heart failure results from the inability of the right ventricle to function properly. Blood isn’t pumped to the lungs as quickly as it returns from the other parts of the body. Fluid then begins to back up in the veins and pushes out into the tissues‚ causing edema‚ most often in the feet‚ lower legs‚ and ankles. (Cadwallader p. 1142). Sluggish blood flow also deprives organs of oxygen and other nutrients causing fatigue and

and extracellular fluids. The distribution of water between the two fluids is determined by osmotic pressure. Water can freely cross cell membranes keeping body fluids at an osmotic equilibrium. Equilibrium is reached when the osmotic pressure is equal in both intracellular and extracellular fluids. When there is excess water within the body‚ the kidneys absorb the water and secrete it was urine‚ this returns the water level to its osmotic equilibrium. The water and electrolyte balance within the
