<TR>
<TD>Define Glomerular Filtration Rate.</TD>
<TD>
<FONT COLOR="#FFFFFF">The glomerular filtration or GFR is the amount of fluid filtered from the capillaries into the Bowmans capsule per unit time.</FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Introduction|Link]]</TD>
</TR>
<TR>
<TD>By which formula can GFR be expressed?</TD>
<TD>
<FONT COLOR="#FFFFFF">GFR = K<sub>f</sub> x net filtration pressure</FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Introduction|Link]]</TD>
</TR>
<TR>
<TD>What determine renal blood flow and capillary hydrostatic pressure?</TD>
<TD>
<FONT COLOR="#FFFFFF">Arterial blood pressure coupled with the contraction of both the afferent and efferent arterioles</FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Regulation of Renal Blood Flow and Capillary Hydrostatic Pressure|Link]]</TD>
</TR>
<TR>
<TD>Why is it important that the constriction of the afferent and efferant arterioles changes with blood pressure?</TD>
<TD>
<FONT COLOR="#FFFFFF">To maintain renal blood flow</FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Regulation of Renal Blood Flow and Capillary Hydrostatic Pressure|Link]]</TD>
</TR>
<TR>
<TD>What effect does contracting the afferant arteriole have on filtration pressure?</TD>
<TD>
<FONT COLOR="#FFFFFF">Reduces filtration pressure</FONT></TD>

</TR>
<TR>
<TD>What are the two mechanisms for pressure autoregulation</TD>
<TD>
<FONT COLOR="#FFFFFF">
* The Myogenic Response
* Tubuloglomerular Feedback</FONT></TD>
<TD>[[Autoregulation of GFR - Anatomy and Physiology#Pressure Autoregulation|Link]]</TD>
</TR>
<TR>
<TD>Which mechanism works by responding to increased stretch in the arterioles by constricting them to a smaller diameter?</TD>
<TD>
<FONT COLOR="#FFFFFF">The Myogenic Response</FONT></TD>
<TD>[[Autoregulation of GFR - Anatomy and Physiology#Myogenic Response|Link]]</TD>
</TR>
<TR>
<TD>Which structure in the wall of the distal tubule detects an increase in NaCl when blood pressure increases?</TD>
<TD>
<FONT COLOR="#FFFFFF">The Macula Densa</FONT></TD>
<TD>[[Distal Tubule - Anatomy & Physiology#Juxtaglomerular Apparatus|Link]]</TD>
</TR>
<TR>
<TD>What is the effect of increased sympathetic activity on the kidneys?</TD>
<TD>
<FONT COLOR="#FFFFFF">
* Reduced renal blood flow
* Small decrease in excreted waste
* Increased conservation of water and sodium</FONT></TD>
<TD>[[The Role of the Sympathetic Nervous System on GFR - Anatomy & Physiology|Link]]</TD>
</TR>
<TR>
<TD>What is Renal CLearance?</TD>
<TD>
<FONT COLOR="#FFFFFF">
Renal clearance is the ability of the kidney to remove a compound from the blood</FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Renal Clearance|Link]]</TD>
</TR>
<TR>
<TD>What other methods of clearance apart from the body apart from renal are there?</TD>
<TD>
<FONT COLOR="#FFFFFF">
* Biliary
* Pulmonary
* Salivary </FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Renal Clearance|Link]]</TD>
</TR>
<TR>
<TD>For the renal clearance of a substance to represent the GFR which two things must not happen to it as it moves along the nephron?</TD>
<TD>
<FONT COLOR="#FFFFFF">
It must not be reabsorbed or further secreted </FONT></TD>
<TD>[[Glomerular Filtration Rate (GFR) - Physiology#Renal Clearance and GFR|Link]]</TD>
</TR>
<TR>
<TD>Name three compounds which can be used to measure GFR from Renal clearance.</TD>
<TD>
<FONT COLOR="#FFFFFF">
* Inulin
* Creatinine
* Urea</FONT></TD>
