25 Cards in this Set

  • Front

In the human body, the kidneys are found lateral to the "linea albe."
False, vertebral column
The renal pyramids are found primarily in the "cortex" of the kidney.
False, medulla
Just before leaving the kidney, the urine flows through a funnel-shaped structure known as the "major calyx."
True
The renal artery delivers blood to the glomerulus by means of the "efferent" arteriole.
False, afferent
During the process of "active transport," plasma from the blood leaves the glomerulus and enters the glomerular capsule.
False, filtration
The fluid in the glomerular filtrate normally contains no blood cells or "amino acids."
False, proteins
7. not on exam
N/A
8. not on exam
N/A
Immediately after leaving the glomerulus, the blood enters the "peritubular capillary."
False, efferent arteriole
The process of active transport accounts for the reabsorption of amino acids and "starch" molecules in the proximal convoluted tubule.
False, glucose
In the proximal convoluted tubule, the release of water is related to the process of "phagocytosis."
False, osmosis
The pulling power exerted on water molecules is due to an accumulation of "calcium-phosphate" molecules.
False, sodium chloride
The descending and ascending limbs of the loop of Henle are found in the "cortex" of the kidney.
False, medulla
Certain organic compounds such as "urea" leave the lower portion of the collecting duct and exert a pulling power on water.
True
The process by which water flows from the tubules in response to the high sodium chloride concentration in the surrounding are is an "active" process.
False, passive
The process by which compunds move from the peritubular capillary into the distal convoluted tubule is known as "tubular excretion."
True
The antidiuretic hormone regulates the rate of reabsorption of water from the "glomerulus."
False, collecting tubule
The secretion of antidiuretic hormone is stimulated when chemical receptors in the "thalamus" respond to an increase in blood pressure.
False, hypothalamus
The hormone aldosterone has a substantial impact on the reabsorption of "calcium" ions from the distal tubules of the nephron.
False, sodium
The condition known as "Wellington's" disease may result from an inadequate secretion of aldosterone.
False, Addison's
Urea, a major component of the urine, is produced by the "brain" during its metabolism.
False, liver
"Ketone bodies" are found in the urine when a diabetic is using fat as his primary energy source.
True
The urethra is the longer tubule in "females."
False, males
Pigments that give color to the urine are derived form substances produced primarily in the "pancreas."
False, liver
The skin is considered an excretory organ because it excretes water and "salts" in the perspiration.
True
