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
