In response to increased levels of aldosterone, the kidneys produce:- a larger volume of urine.- urine with less glucose.- urine with a higher concentration of sodium ions.- urine with a lower concentration of sodium ions.- urine with a lower concentration of potassium ions.
The nephron is responsible for maintaining _______.- Acid-base balance in the body- Electrolyte balance in the body- Fluid balance in the body- All of the above
Antidiuretic hormone- Is secreted by the anterior pituitary.- Release is insensitive to the osmolarity of interstitial fluid.- Increases the permeability of the collecting ducts to water.- Causes the kidneys to produce a larger volume of very dilute urine.- Is secreted in response to low potassium ion in the blood.
The secretion of ADH is directly stimulated by _______.- Renin- Angiotensin I- A change in body fluid osmolarity- Angiotensin II
Which of the following have the same effect on plasma pH?- excretion of bicarbonate and excretion of H+- reabsorption of bicarbonate and excretion of H+- reabsorption of bicarbonate and reabsorption of H+- all of the above
The ureters and urinary bladder are lined by ________ epithelium.- Pseudostratified columnar- Stratified squamous- Transitional- Simple columnar- Simple cuboidal
The majority of glomeruli are located in the ________ of the kidney.- Calyces- Cortex- Vasa recta- Medulla- Pelvis
Which of the following describes the order in which blood flows through the nephron?- Efferent arteriole, glomerulus, afferent arteriole- Glomerulus, afferent arteriole, efferent arteriole- Afferent arteriole, efferent arteriole, glomerulus- Afferent arteriole, glomerulus, efferent arteriole
When ADH is present _______.- Urine concentration increases- Urine output increases- Urine concentration increases and urine output increases- Urine concentration decreases- Urine concentration decreases and urine output increases
A glomerulus is- The source of erythropoietin.- Attached to the collecting duct.- The expanded end of a nephron.- The horseshoe-shaped segment of the nephron.- A knot of capillaries within the renal corpuscle.
Which of the following should NOT be found in the filtrate in the Bowman's capsule?- Sodium- White blood cells- Potassium- Glucose
Which of the following is not a function of the urinary system?- Eliminates organic waste products- Excretes excess albumin molecules- Regulates blood volume- Contributes to stabilizing blood pH- Regulates plasma concentrations of electrolytes
Which of these components of the nephron is largely confined to the renal medulla?- Proximal convoluted tubule- Glomerular (Bowman's) capsule- Collecting ducts- Distal convoluted tubule- Glomerulus
The structure known as the juxtaglomerular apparatus is located near the- The proximal convoluted tubule.- Renal papilla.- The collecting duct.- The nephron loop (loop of Henle).- Glomerulus.
