 Assignment #2  Due in Unit 9  Organs of the Urinary System  Kidneys  Formation of Urine  Hormones Affecting Urine Volume  Organs of the Urinary System, Continued  Ureters, Bladder, Urethra  Micturition

 Kidneys  Ureters  Bladder  Urethra  Blood Supply  Renal artery  Renal vein  Page 440

 Kidneys  Retroperitoneal  Renal Cortex  Renal Medulla  Renal Pyramids  Renal Pelvis  Renal Calyx  Page 441

 Nephron  Bowman’s capsule  Proximal convoluted tubule  Loop of Henle  Distal convoluted tubule  Collecting tubule  Page 443

 Blood supply  Afferent arteriole  Glomerulus  Efferent arteriole  Peritubular Capillaries

 Filtration  Renal corpuscle  Reabsorption  Everywhere, except renal corpuscle  Secretion  Occurs in distal convoluted tubules and collecting tubules  Page 446

 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.
