Front Back
Basin within the kidney that collects the urine made by the kidney
Renal Pelvis
The lighter outer region of the kidney called the renal cortex extends inward to form these structures
Renal Columns
the darker inner region of the kidney called the renal medullar forms these striped cone-shaped regions
Renal Pyramids
Cuplike edges of the renal pelvis that receives the urine from the renal pyramids and empty it into the renal pelvis
Tough outer lining that encases the kidney
Renal Capsule
A triangle formed by the two points of entrance of the ureters and the exit point of the urethra
The ureter enters the bladder at this point
Detrusor Muscle
reabsorption causes water and solute to move from the tubule into this structure
Peritubular Capillaries
Composed of an ascending and descending limb
Loop of Henle
The site at which ADH is most active
Collecting Duct
The afferent and efferent arterioles bracket this structure
Site at which aldosterone is most active
Distole Convoluted Tubule
Hormone that stimulates the adrenal cortex to secrete aldosterone and causes vasoconstriction of the peripheral blood vessels, thereby elevating blood presure
Angiotensin II
The adrenal cortical hormone that stimulates the distal tubule to reabsorb sodium and excrete potassium
Enzyme that changes angion tensin I to angiontensin II
Converting Enzyme
Secreted by the posterior pituitary gland; this hormone affects the permeability of the collecting duct to water
Released by the kidney in response to hypoxemia; it stimulates red blood cell production by the bone marrow
Secreted by the juxtaglomerular apparatus (JGA) when blood pressure and or blood volume decreases
Secreted by the atrial walls in response to an increase in blood volume; it causes the excretion of sodium and water
Enzyme tha tactivates angiontensinogen to angion tensin I
a deficiency of this hormone causes polyuria, sometimes up to 25 liters of urine per day; this hormone deficiency disease is called diabetes insipidus
Stimulates the renal tubules to reabsorb calcium and to excrete phosphate
Hormone that is released in response to ventricular stretch; elevated in heart failure
A deficiency of this hormone causes hypocalcemic tetany
Hormone that is deficient in a patient with chronic renal failure; causes anemia
ACE inhibitors block the formation of this vasopressor hormone
A deficiency of this hormone causes the urinary excretion of Na and water and the retention of K.
An excess of this hormone can cause hypercalcemia and kidney stones.
