Structure and Function of the Mammalian Kidney 2
100
Degradation product of proteins and nucleic acids that are toxic at high concentrations and must be eliminated from the body.
What is nitrogenous waste
100
An animal whose osmolarity conforms to that of its environment.
What is osmoconformer
100
In animals, the process of expelling waste or harmful materials from the body.
What is excretion
100
The major excretory organ found in all vertebrates.
What is kidney
100
One of several million single-cell-thick tubules that are the functional units of the mammalian kidney.
What is nephron
200
A nitrogenous waste commonly produced in many terrestrial species, including mammals.
What is urea
200
The passive removal of water and small solutes from the blood during the production of urine.
What is filtration
200
The part of the filtrate formed in the kidney that remains after all reabsorption of solutes and water is complete.
What is urine
200
A structure in the mammalian urinary system through which urine flows from the kidney into the urinary bladder.
What is ureter
200
A filtering component in the nephron of the kidney.
What is renal corpuscle
300
A nitrogenous waste produced by birds, insects, and reptiles.
What is uric acid
300
In the process of filtration in an excretory system, the material that passes through the filter and enters the excretory organ for either further processing or excretion.
What is filtrate
300
Simple excretory organs found in flatworms that are used to filter out wastes and excess water.
What is photonephridia
300
The structure in the mammalian urinary system that collects urine before it is eliminated.
What is Urinary Bladder
300
A cluster of interconnected, fenestrated capillaries in the renal corpuscle of the kidney; the site of filtration in the kidney.
What is glomerulus
400
The solute concentration of a solution of water, expressed as milliosmoles/liter (mOsm/L).
What is osmolarity
400
In the production of urine, the process in which useful solutes in the filtrate are recaptured and transported back into the body fluids of an animal.
What is reabsorption
400
Excretory filtration organs found in a variety of invertebrates.
What is metanephridia
400
The structure in the mammalian urinary system through which urine is eliminated from the body.
What is Uretha
400
Blood vessels that provide a pathway for blood into the glomeruli of the vertebrate kidney.
What is afferent arterioles
500
An animal that maintains stable internal salt concentrations and osmolarities, even when living in water with very different osmolarities than its body fluids.
What is osmoregulator
500
In the production of urine, the process in which some solutes are actively transported into the tubules of the excretory organ; this supplements the amount of a solute that would normally be removed by filtration alone.
What is secretion
500
Delicate projections from the digestive tract of insects and some other taxa that function as an excretory organ.
What is malphigian Tubules
500
The structures that collectively act to filter blood or hemolymph and excrete wastes, while recapturing useful compounds.
What is Urinary System
500
A blood vessel that carries blood away from a glomerulus of the vertebrate kidney.
What is efferent arterioles
