 * Assessment statements ** (IBO notes added to some points to clearly indicate what needs to be understood and what does not)
 * 11.3.1 || Define excretion. ||
 * 11.3.2 || Draw and label a diagram of the kidney. Include the cortex, medulla, pelvis, ureter and renal blood vessels. ||
 * 11.3.3 || Annotate a diagram of a glomerulus and associated nephron to show the function of each part. ||
 * 11.3.4 || Explain the process of ultrafiltration, including blood pressure, fenestrated blood capillaries and basement membrane. ||
 * 11.3.5 || Define osmoregulation. ||
 * 11.3.6 || Explain the reabsorption of glucose, water and salts in the proximal convoluted tubule, including the roles of microvilli, osmosis and active transport. ||
 * 11.3.7 || Explain the roles of the loop of Henle, medulla, collecting duct and ADH (vasopressin) in maintaining the water balance of the blood. Details of the control of ADH secretion are only required in option H (see H.1.5). ||
