Fundamentals-Renal Flashcards
What is the function of the Macula densa?
It reads the “constituents” of the juxtaglomerular apparatus and adjusts the “tone” of the efferent and afferent arterioles.
What is “nephrotic syndrome”?
A condition in which there is leakage of very large amounts of protein from the glomerulus resulting in massive proteinuria.
What happens to Renal Blood Flow if the afferent arteriole in constricted?
Decreases
What happens to Renal Blood Flow if the afferent arteriole in dilated?
Increases
How much filtrate (in liters) does the Glomerulus make in a day?
About 90 liters
What is the main function of the Loop of Henle?
To concentrate the urine.
What if creatinine clearance is low?
Probably a loss of functioning nephron units.
The descending Loop of Henle is highly permeable to what?
Water and small solutes.
What does ADH (Antidiuretic Hormone) do?
Secretion helps the body conserve water by…..
What does Aldosterone do?
Promotes the reabsorption of Na+
What is the release of Aldosterone controlled by?
The Renin-Angiotensin-Aldosterone System
Where is Aldosterone produced and stored?
Produced and stored by the adrenal gland under the direction from the pituitary gland.
What are the Types of Acute Renal Failure?
Renal Hypo-perfusion (Pre-renal), Intrinsic Acute Renal Failure, and Post Renal Failure (obstruction)
