Bio Vocab Review Ch. 44

The action of this hormone makes the epithelium of the collecting ducts more permeable to water.

ADH

This process recovers useful molecules and water from the kidney filtrate and returns them to the body fluid.

reabsorption

This animal waste product incorporates the most nitrogen atoms and is the most metabolically expensive to synthesize.

uric acid

The osmolarity of the filtrate is lowest within this part of the nephron.

DCT

This hormone causes the distal tubules and collecting ducts to reabsorb more Na+ and water, thereby increasing blood volume and pressure.

aldosterone

An animal that has access to copious amounts of water will most likely secrete this as its nitrogenous waste product.

ammonia

In designing a kidney for use in an arid environment, this would be the nephron of choice.

juxtamedullary nephron

This type of nephron has a loop of Henle that extends deep into the renal medulla.

juxtamedullary nephron

In the mammalian kidney, energy must be constantly expended to maintain the osmotic gradient between the cortex and medulla. This expenditure largely occurs in the...

loop of Henle - thick ascending limb

When blood pressure or volume drops in the afferent arteriole, this enzyme is released by the JGA.
