Place urine production in order of how it travels.
renal pyramid → minor calyx → major calyx → renal pelvis → ureter
renal pyramid → major calyx → minor calyx → renal pelvis → ureter
renal pelvis → minor calyx → major calyx → renal pyramid → ureter
renal pelvis → major calyx → minor calyx → renal pyramid → ureter
Which statement about the juxtaglomerular complex is false?
juxtaglomerular cells, in the afferent arteries, secrete renin
not involved in the hormonal regulation of blood pressure
macula densa cells, in the distal tubule, function as chemoreceptors and baroreceptors
mesangial cells provide feedback control between macula densa and juxtaglomerular cells
Which of he following statements about the kidneys is false?
each kidney has an adrenal gland on top
highly vascular
right kidney is slightly superior to left kidney
located between vertebrea T12 and L3
Which regions are parts of the retroperitoneal kidneys not located in?
lumbar
epigastric
hypochondriac
Under normal circumstances, metabolic waste eliminated by the urinary system include all but:
creatinine, from the breakdown of creatine phosphate from muscle contractions
uric acid, formed during recycling of nitrogenous bases from RNA molecules
glucose, proteins, and amino acids
urea, from the breakdown of amino acids
Which layer of the filtration membrane prevents the passage of blood cells?
fenestrated endothelium
foot processes of podocyes
basement membrane
Which of the following is false?
GFR = (NHP - BCOP)
NHP = (GHP - CsHP)
glomerular hydrostatic pressure (GHP) tends to draw material out of the plasma
blood colloid osmotic pressure (BCOP) tends to push material into the plasma
capsular hydrostatic pressure (CsHP) tends to push material into the plasma
NFP = (NHP - BCOP)
Which statements is false? Remember pH less than 7 is acidic, pH greater than 7 is alkaline (basic).
exhaustive muscle activity can cause lactic acidosis (low blood pH)
starvation and diabetes mellitus can cause ketoacidosis (low blood pH)
prolonged aldosterone stimulation can cause alkalosis (high blood pH)
normal average blood pH is 2
Which region are the retroperitoneal adrenal glands located in?
lumbar
epigastric
hypochondriac
The thin descending limb of the nephron loop reabsorbs water, and the thick ascending loop reabsorbs sodium and chloride ions.
true
false
Which layer of the filtration membrane does not prevent the passage of plasma proteins?
basement membrane
foot processes of podocyes
fenestrated endothelium
The removal of waste from body fluids is called __________, and the discharge of waste out of the body is called __________?
elimination, excretion
filtration, excretion
excretion, elimination
filtration, elimination
Order the veins from a nephron.
renal → segmental → interlobar → arcuate → cortical radiate → afferent
venule → cortical radiate → interlobar → arcuate → renal
renal → segmental → arcuate → interlobar → cortical radiate → afferent
venule → cortical radiate → arcuate → interlobar → renal
Which pathway involving angiotensin II and GFR homeostasis isn't accurate?
angiotensin II → aldosterone → increased sodium retention → increased blood volume
angiotensin II → nervous system → parasympathetic activation → increased cardiac output
angiotensin II → nervous system → increased thirst/ADH production → increased blood volume
juxtaglomerular → renin → angiotensin I → lungs → angiotensin II → adrenal glands → aldosterone
Order the arteries to a nephron.
renal → segmental → interlobar → arcuate → cortical radiate → afferent
venule → cortical radiate → interlobar → arcuate → renal
