Substance formed in the blood by the action of the renal enzyme renin; it increases the blood pressure by causing a vascular constriction and stimulating the release of aldosterone from the adrenal cortex
angiotensin
Hormone released from the posterior pituitary gland that increases water reabsorption in the kidneys, thus describing the urinary output
antiduretic hormone (ADH)
Substance that prevents sharp changes in the PH of solution
buffer
Compound that seperates into ions in solution; substance that conducts an electrical current in solution
electrolyte
Hormone released from the kidney that stimulates red blood cell production in the red bone marrow
erythropoietin
Removal and elimination of metabolic waste products from the blood
excretion
Outside the cell
extracellular
Fluid and dissolved materials that leave the blood and enter the kidney nephron through the glomerular (Bowman) capsule
glomerular filtrate
Cluster of the capillaries in the nephron's glomerular (Bowman) capsule
glomerulus
Between, pertaining to an organ's spaces or structures between active tissue
interstitial
Between cells
intracellular
Organ of excretion
kidney
Act of urination; voiding of the urinary bladder
micturition
Microscopic functional unit of the kidney
nephron
Symbol indicating hydrogen ion (H+) concentration; scale that measures the relative acidity and alkalinity (bascity) of a solution
pH
Enzyme released from the kidneys juxtaglomerular appartus that indirectly increases blood pressure by activating angiotensin
renin
Nitrogenous waste product excreted in the urine; end product of protein metabolism
urea
Tube that carries urine from the kidney to the urinary bladder
ureter
Tube that carries urine from the urinary bladder to the outside of the body
urethra
Hollow organ that stores urine until it is eliminated
