Question	Answer
The organs of the urinary system are	Paired kidneys, paired ureters, a bladder, & a urethra
A renal corpuscle includes the	Glomerulus and glomerular capsule
A nephron consist of	A renal corpuscle and a renal tubule
The parts of a renal tubule in correct sequence from beginning to end	Proximal convoluted tubule, descending limb of nephron loop, ascending limb of nephron loop, & distal convoluted tubule
A renal corpuscle is a _____, whereas a renal tubule is a _____.	Cluster of blood capillaries and glomerular capsule Highly coiled tubule exiting the glomerular capsule
Once in the glomerular capsule, the filtrate moves into the	Renal tubule
The reabsorption of glucose occurs primarily through the walls of the	Proximal convoluted tubule
What increases the rate of glomerular filtration?	Increased blood pressure
What regions of the nephron is water actively transported?	None of the above
As a result of very low arterial blood pressure, glomerular hydrostatic pressure	Drops & filtration decreases
Aldosterone from the adrenal cortex causes sodium ions to be	Conserved & potassium ions to be excreted
An increase in glomerular osmotic pressure ____ the rate of glomerular filtration	Decreases
Filtration rate in the glomerulus is increased by	Both vasodilation of the afferent arteriole & vasoconstriction of the efferent arteriole
The juxtaglomerular apparatus regulates the filtration rate by	Renin-angiotensin 2 vasoconstricting both the afferent & efferent arterioles
A decrease in the glomerular capsule hydrostatic pressure will ____ the rate of glomerular filtration	Increase
If glucose is not reabsorbed in the tubular fluid ____ increases	The osmotic pressure
Secretion of atrial natriuretic peptide ( ANP )	Increases sodium excretion
The ________ is the layer that contains the structures that function to filter the blood, called _______. Most renal tubules are located in this layer.	Renal cortex Glomeruli
The _________ is the layer that contains the segment of renal tubules called nephron loops that function to produce a hypertonic medullary interstitial fluid.	Renal medulla
The _________ is the hollow portion of the kidney, filled with vessels, the renal calyces & renal pelvis.	Renal sinus
Water reabsorption from the proximal convoluted tubule is closely linked to the active reabsorption of ______.	Sodium ions
The _______ ______ acts as the counter current multiplier.	Nephron loop
The increase in osmolarity as filtrate moves down the descending limb is due to ______ moving out of the tubule.	Water
The decrease in osmolarity of the filtrate as it moves up the ascending limb due to _____ moving out of the tubule.	Solutes
The filtrate is _______ at the tip of the nephron loop & _____ at the end of the ascending limb.	Hypertonic Hypotonic
The concentration gradient found in the renal tubules is also found in the interstitial fluid of the ______.	Renal medulla
Renal secretion occurs as	Substances pass from the peritubular capillaries to the nephron tubules
Describe renal filtration	Fluid leaves the glomerulus & enters the bowman's (glomerular) capsule
Increases filtration	Increase in blood pressure Constriction of the efferent arteriole
Decreases filtration	An increase in capsular pressure An increase in plasma protein concentration An obstruction in the proximal tubule
Process occurring at the nephron	Filtration---> reabsorption---> secretion
Responsible for removing substances from blood, urine, & help regulate certain metabolic processes	Kidney
Transport of urine from the kidneys	Ureters
Collects urine from the ureters	Urinary bladder
*** transports urine out of the body	Urethra
Reddish brown bean shaped organ with a smooth surface	Kidney
