Antidiuretic Hormone and Aldosterone

Which substances are reabsorbed or excreted is controlled by two hormones. What are they?

Antidiuretic Hormone

_____________________ ___________________ increases water retention by making the collecting duct and distal convoluted tubule permeable to water.

Aldosterone

________________________ stimulates the secretion of potassium ions and the reabsorption of sodium ions.

nephrons/glomeruli/glomerular filtrate

The two million ___________________ of the kidney maintain fluid homeostasis by filtering 180 liters of fluid through their _____________________ each day to create the _______________________ __________________.

Specific Gravity

________________ _________________ compares the density of urine with the density of water to determine the concentration of solutes in the urine.

refractometer

What tool was used to measure the specific gravity of the urine samples.
