Excretion The removal of metabolic wastes from the body
Fluid compartments **No per instructor** The 2 locations for water in the body - intracellular and extracellular
Glomerulonephritis An inflammation of the filtration membrane in the glomerulus to produce hormones
Hyperkalemia Condition in which the level of K+ (potassium) in the blood is too high
Hyponatremia Condition in which the level of Na+ (sodium) in the blood is too low
Metabolic acidosis **No per instructor** Condition in which there is decreased elimination of hydrogen ions by the kidneys or increased production of acidic substances through metabolism

Nitrogenous wastes Wastes removed from the blood by the kidneys; include ammonia, urea, uric acid, and creatinine
Renal corpuscle **No per instructor** Part of a nephron; composed of a glomerulus and glomerular capsule
Renal tubule **No per instructor** Part of a nephron; composed of proximal convoluted tubule, nephron loop, and distal convoluted tubule
Respiratory acidosis **No per instructor** Condition in which the respiratory system cannot eliminate sufficient CO2 (carbon dioxide)
Respiratory alkalosis **No per instructor** Condition in which the respiratory system eliminates too much CO2 (carbon dioxide)
Secretion The third process of urine production in the nephron; removes remaining wastes and excess hydrogen ions form the blood
