Which is not a major function of the kidney?
regulation of blood cell size
This is the formation of a new glucose molecule.
gluconeogenesis
Which of the following is a waste product normally excreted by the kidneys?
urea
This is smooth dense irregular connective tissue that is continuous with the outer coat of the ureter.
renal capsule
The portion of the kidney that extends between the renal pyramids is called the
renal columns
Which is the correct order of blood flow?
interlobular arteries-arcuate arteries-glomerular capillaries-arcuate veins
Which is the correct order of filtrate flow?
glomerular capsule, Proximal Convoluted tubule (PCT), Loop of Henle, Distal Convoluted tubule (DCT), Collecting duct
Which structure of the nephron reabsorbs the most substances?
Proximal convoluted tubule
This is the structure of the nephron that filters blood.
glomerular capsule
This term means entry of substances into the body from the filtrate.
reabsorption
This is a nephron process that results in a substance in blood entering the already formed filtrate.
secretion
This layer of filtration membrane is composed of collagen fibers and proteoglycans in a glycoprotein matrix.
basal lamina
This occurs when stretching triggers contraction of smooth muscle walls in afferent arterioles.
myogenic mechanism
This is when a substance passes from the fluid in the tubular lumen through the apical membrane then across the cytosol into the interstitial fluid.
transcellular reabsoprtion
Once fluid enters the proximal convoluted tubule
it is called tubular fluid
The proximal convoluted tubules reabsorb what percentage of filtered water?
65%
Which of the following is a way angiotensin II affects the kidneys?
It increases GFR
Urea recycling can cause a buildup of urea in the
Renal medulla
Increased secretion of Hydrogen ions would result in a ______________ of blood ____________?
decrease, pH
Increased secretion of Aldosterone would result in a ______________ of blood ____________?
increase, sodium
The ascending loop of Henle is impermeable to
water
An analysis of the physical, chemical and microscopic properties of urine is called
Urinalysis
This is a test to measure kidney function.
Plasma creatinine
This transports urine from the kidney to the bladder.
Ureter
This layer of the ureter is composed of connective tissue, elastic and collagen fibers.
Lamina propria
This lies in the anterior cornea of the trigone of the bladder.
Internal urethral orifice
