Unit #5 Urinary Review - Assignment #15 Flashcards
In the kidney, a concentration of 1200 mOsm would be found in which of the following areas:
Medulla
Bend of the nephron loop/hairpin turn
Bottom of the vasa recta/hairpin turn
Blood pressure would decrease due to the release of which of the following:
atrial natriuretic peptide
Blood volume would increase due to the release of which of the following:
aldosterone
antidiuretic hormone
If HPgc = 52 mmHg, HPcs = 12 mmHg, and OPgc = 32 mmHg, what is the Net Filtration Pressure? DO NOT INCLUDE UNITS IN YOUR ANSWER.
8
Which of the following could increase GFR?
-Dilated afferent arteriole with a normal diameter efferent arteriole
-Constricted efferent arteriole with a normal diameter afferent arteriole
-Stimulation of the macula densa cells
In which part of the nephron does most reabsorption take place?
proximal convoluted tubule
Juxtaglomerular cells of the juxtaglomerular complex secrete ________________ when ___________
renin; blood pressure drops
Hydrostatic pressure is the primary driving force of plasma through the filtration membrane into the capsular space. All but one of the following statements reflects why hydrostatic pressure is so high in the glomerular capillaries. Select the one statement that does NOT explain the high pressure within the glomerular capillaries.
The flow of blood is reduced as blood reaches the efferent arteriole.
The efferent arteriole has higher resistance to blood flow than the afferent arteriole.
The volume of plasma in the efferent arteriole is higher when compared to the afferent arteriole.
The diameter of the efferent arteriole is smaller than the afferent arteriole.
The volume of plasma in the efferent arteriole is higher when compared to the afferent arteriole.
The macula densa cells respond to ________.
changes in Na+ content of the filtrate
What is the most direct function of the juxtaglomerular apparatus?
help regulate blood pressure and the rate of blood filtration by the kidneys
