Can you solve these MCQ's on tubular function and GFR, before downloading the powerpoint.

1. What is Glomerular capillary hydrostatic pressure?
   a) 20 mmHg
   b) 30 mmHg
   c) 40 mmHg
   d) 50 mmHg
   e) 60 mmHg
2.  Which of the following would cause an increase in both glomerular filtration rate（GFR）and renal plasma flow（RPF）？                                      

       A. Hyperproteinemia                    

   B. A ureteral stone

      C. Dilation of the afferent arteriole         

   D. Dilation of the efferent arteriole

      E. Constriction of the efferent arteriole

     3.  Glucose reabsorption occurs in the                                    

        A. proximal tubule              

        B. loop of Henle           

        C. distal tubule

4.   Regarding the renal circulation

a) The kidneys receive about 10% of the resting cardiac output

b) As cardiac output increases during exercise renal blood flow rises

c) Renal blood flow is maintained within narrow limits despite changes in arterial blood pressure

   d) Increased activity in the renal sympathetic nerves results in increased blood flow to the kidneys.

Give reason why you select one answer and not the others . 

Triggers for next class for MGMCRI students

Clearance - Inulin
                - PAH

Tubular transport maximum

Splay

Concentration of substances along length of tubule -- Why does it vary

Glomerular filtration

Please go through the powerpoint and get your concepts clear about forces and factors affecting GFR.

It is one of the most common question asked from renal system .

Q . Can high protein diet affect glomerular filtration rate ?.....Answer appears simple but there is a catch.....Guyton first chapter on excretory system gives the answer...Go dig it out and answer on the blog .

Thought for the day:

If there is no struggle, there is no strength

Introduction to excretory system

Hi.

I m back to business again.

Now posting powerpoints of excretory system.

This is basically for the students. But can be of help to everybody.

I would be posting questions for students. If they feel they can go for a happening discussion.





Related questions to explore

1. Differences between cortical and juxtamedullary nephrons and physiological importance of the differences.

2. Importance of histological differences of various parts of tubule

3. What is safety factor. How is it applicable to kidney.

Are u up for discussion ?
