of the glomerulus.
Four steps in the formation of urine - Answer -1. Glomerular filtration
2. Tubular reabsorption
3. Tubular secretion
4. Water reabsorption
parenchyma - Answer -Fundamental tissue composed of thin-walled living cells that
function in photosynthesis and storage. (kidney parenchyma is the nephron) 1 million in
each kidney
Aldosterone - Answer --controls salt and water balance of the body
-regulated by the renin-angiotensin system
JGA - Answer -juxtaglomerular apparatus
juxtaglomerular apparatus - Answer -in the nephron, the complex of cells from the distal
tubule and the afferent arteriole which helps regulate blood pressure by secreting renin
in response to blood pressure changes in the kidney; located near the glomerulus
, antidiuretic hormone (ADH) - Answer -Hormone produced in hypothalamus that
stimulates water reabsorption from kidney tubule cells into the blood and
vasoconstriction of arterioles.
diabetes inspidus (DI) - Answer -caused by hypo secretion of ADH by the pituitary
gland. Characterized by the symptoms of polydipsia and polyuria
diabetes mellitus - Answer -insulin is not secreted adequately or tissues are resistant to
its effects

glomerulonephritis - Answer -inflammation of the glomeruli of the kidney
interstitial nephritis - Answer -inflammation of the connective tissue that lies between
the renal tubules
hydronephrosis - Answer -abnormal condition of water in the kidney, due to blockage in
ureter and urethra
nephrolithiasis - Answer -condition of stones in the kidney
extracorporeal lithotripsy - Answer -noninvasive mechanical procedure for using sound
waves to break up renal calculi so that they can pass through the ureters
nephrolithotomy - Answer -incision into a kidney to remove a stone
percutaneous nephrolithotomy (PCNL) - Answer -surgeon makes small incision through
skin into the kidney. a nephroscope is inserted into the kidney to remove the stone.
