Reabsorption Everywhere, except

renal corpuscle Secretion

Occurs in distal convoluted tubules and collecting tubules

Anti-diuretic Hormone (ADH) Reabsorption of water from collecting

tubules Secreted by Posterior Pituitary gland

Aldosterone Reabsorption of sodium Secreted by Adrenal Cortex

Atrial natriuretic hormone (ANH) Secretion of sodium Secreted by atrial walls of the heart

The kidneys function as important homeostatic mechanisms for many conditions in the body. Predict what changes in urine production would occur in a patient who suffered a surgical injury to the hypothalamus.
