    That's funny. I can usually study better at school because here at home, I am always thinking of things I need to do. The only draw back to that, is there is always someone coming up and talking if I am at school.

    Thank you, and Happy Thanksgiving to you, and everyone else. Congrats on your last test grade. It is good that even though you are in the program, you are still giving it all you have.

    That's the way I always look at things. I have done good enough that I could make a really low grade on both of my finals and still pull an A, but how would that look to my instructor, or anyone else who might look at my grades? I would not feel so good about myself either.

    Hello,
    Bit of a lurker here but was hoping someone could help me with an assignment. I need to list all the specific substances that are filtered secreted and reabsorbed in the nephron during urine formation. I want to have a complete list so I thought I ask all the Ap2 students so I can make sure I did not miss any. TIA Lisa

    Why don't you tell us what you came up with so that we could add whatever necessary....nephron function is very complicated and envolved different things are secreted and absorbed at different places....I have huge tables in my book talking about it...it would take days to put it all up here

    BAsically water , salt and potassium leave or are reabsorbed according to demand...too much of any of these and it will be transported out. Not enough and they will be retained.
    All the big ions are not able to make it through the holes in the capillaries, example proteins.

    Ok this is what I have so far. These substances are filtered in the glomerulus water, sodium,glucose,chloride,potassium,phosphate,urea,u ric acid,creatin,small hormones such as steroids,calcium, hco. thanks Lisa

    Looks like you got it pretty close....as far as my book is concerned the renal corpuscle filters blood plasma without the plasma proteins..so whatever is in your blood at any given time will be filtered...water , inorganic and organic solutes (this is where the trouble is...my book only mentions the most important that you already named) the blood plasma proteins and bloodcells stay behind. Maybe look under the composition of blood and don't count the proteins and bloodcells in....this could also include vitamins, histamine, lipids, amino acids and whatever is floating around in your blood this very second :uhoh21: This just came to mind,,,,all your solutes like all your electrolytes...Magnesium, Sufur, Phosphorus and such.... and then there is billirubin and ammonium ions, too Good luck

    Looks like that is about it exept for bicarbonate and hydrogen and some drugs.

    This is my take on it--hope it helps!

    Reabsorbed:
    Glucose, Amino acids, protein, vitamins, lactate, urea, uric acid, Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, H2O--come from the PCT; H2O--come from the descending limb; Na+, Cl-, K+--come from the ascending limb; H2O, urea--from the collecting duct

    Secreted:
    urea, uric acid, creatine, H+, NH4+, some drugs--into the PCT; urea--into the thin portion of ascending limb; H+, K+, NH4+--into the DCT and the collecting duct
