The secondary function of the DCT to reabsorb sodium is controlled by the hormone(s)
aldosterone.
The parietal and visceral epithelia of the glomerular capsule are separated by (the)
capsular space.
Damage to the renal medulla would interfere first with the functioning of the
collecting ducts.
ADH acts mostly on the
collecting system.
Which of the following is a function of the glomerular capsule?
collecting the filtrate from the glomerulus
The last part of the renal tubule is the
distal convoluted tubule.
Blood exits the nephron via
efferent arteriole.
Urine is formed in the
kidney.
Tall cells of the DCT near the vascular pole are called (the)
macula densa.
The large passageways into which the minor calyces empty are the
major calyces.
Cells found between the capillary endothelium and the glomerular epithelium that are important in regulating glomerular blood flow are the
mesangial cells.
After draining through the collecting system, tubular fluid enters (the)
minor calyx.
The best diagnostic test to determine whether or not a person has a kidney stone is
pyelogram
Age-related changes in the urinary system include
reduced sensitivity to ADH
Voluntary urination involves
relaxing the external sphincter and compressing the urinary bladder.
Each kidney ultimately receives blood from
renal arteries.
The primary function of the distal convoluted tubule is
secretion.
Most often, the kidney is confused with the ________ when viewed superficially.
spleen
The structure directly opposite the vascular pole of the glomerulus is the
tubular pole.
Urine is carried to the exterior of the body by the
urethra
In juxtamedullary nephrons, the efferent arterioles and peritubular capillaries are connected to a long, slender series of capillaries that accompany the nephron loops into the medulla. These are (the)
vasa recta.
The main homeostatic function that occurs as a result of the work of the nephron loop is
water and salt conservation.
An obstruction in the glomerulus would increase the blood pressure in the
afferent arteriole.
The thick ascending limb functions to
secrete drugs.
The parts of the urethra in the male, in correct order from the bladder to the exterior, are: (1) urachus (2) spongy urethra (3) dysuria (4) membranous urethra (5) prostatic urethra
5,4,2 prostatic urethra, membranous urethra, spongy urethra
Which area of the nephron completely lacks microvilli and is under hormonal control for the reabsorption of sodium?
DCT
The mechanism whereby benign enlargement of the prostate affects urinary function in older men includes which of the following?
It may compress the prostatic urethra.
Kidneys are often difficult to see without dissection because they are surrounded by a layer of fat. What is the significance of this fat?
It provides cushioning or padding for protection from sudden jolts or other injuries.
In the renal pelvis, fluid processing includes
None of the answers are correct
The filtrate that escapes from the glomerular capillaries includes which of the following?
a fluid similar to plasma, but without the blood proteins
Compared to the PCT, the DCT has
a smaller lumen.
The blood vessels at the boundary of the cortex and medulla of the kidney are the
arcuate artery and vein.
The ureters
are retroperitoneal.
The muscle responsible for stopping the micturition reflex and allowing a person to stop voiding is the
external urethral sphincter.
The glomerulus is made up of many
fenestrated capillaries.
The gaps between the pedicles of the podocytes are called (the)
filtration slits.
A glomerulus
is a capillary knot contained within the renal corpuscle.
The position of the kidneys in the abdominal cavity is maintained, in part, by (the)
overlying peritoneum.
Which of the following drains into the minor calyx?
papillary duct
Urine reaches the urinary bladder by
peristalsis
Urine leaves the renal pelvis and enters the ureter because of
peristalsis of the ureters.
The fluid outside the renal tubule is called
peritubular fluid.
A nephron has two parts:
renal corpuscle and renal tubules.
The expanded end of the nephron is the
renal corpuscle.
The glomerular capsule and the glomerulus make up the
renal corpuscle.
The kidneys are innervated by the
renal nerves.
The kidneys are located
retroperitoneally
Which of the following sits atop the kidneys?
suprarenal glands
Damage, disease, or irritation of the renal cortex would impair the function of which kidney structures?
the nephron units
