huh? wait what are the grade boundries for biosci?

EDIT: sweet, just got 10/10 for vent lab

 

[douseewhatisee]

same old same old

Grade boundaries are typical of any biology paper, 75-79% for A-

Yeah I did pretty good in the test and got the full 20% for labs....

However sadly it doesn't look good for me getting into med.. messed up my core papers and funnily enough I am sitting on 90s for the non-core papers which are useless for Auckland Medicine...

 

[g.walker]

I heard that its lower for biosci106 seeing how everyone tends to screw it up, i believe it was discussed in earlier pages of this thread but i dont know where and nobody was sure. If it is 75-79, ill need a good 62% in the exam to get an A- seeing how badly i always screw up my labs. I dont mind tho, its my trademark, im almost proud to screw up labs seeing how everyone depends on them for grades, cant say im too proud of my medsci labs tho

Hang in there mate, you never know how things turn out, the cutoff still isnt high enough

 

[hamlock]

Oh wow, lots of new dudes. Sweet.

Good luck everyone! Just a few more weeks till freedom. Keep it up.

if anyones still interested

17 of 33 in this file shows you the grade boundaries

I don't think they really deviate from it that much

I got about 79, 75 % in the term test/final exam and 90 something in the
labs which resulted in A overall so trying to keep within those boundaries would be a good target

just try to have a mindset where you expect the worst
lifes like that sometimes :huh:

 

[g.walker]

Hey thanks for the clarification dogtown. Anyway, whatever happens with biosci will be just that, at this point im just aiming for an A+ in medsci, if i get that i'll settle for a B in biosci, albeit im practically aiming for an A/A-

Good luck with the studies everyone, just 3 more days of intense brain abuse and we're done with our studies for good (assuming that physics is as easy to you guys as it is to me (yy))

 

[douseewhatisee]

Haha I really can't wait to finish this year to be honest... I'm tired and whatever happens I guess happens but yeah if I don't make it this year I'm done with Med for good lol no more biosci papers for me

Yeah physics is ridiculously easy, did you take it in NCEA? I still can't believe the class average is so low...

 

[g.walker]

Cambridge but yea i'm also done with med if nothing happens this year, its chemical engineering for me

 

[douseewhatisee]

Anyone wanna take a stab at what Ken Scott will choose as our diagram to recite ?

 

[Origami.Army]

just flick open any page in his lectures and slam your face down, whatever your nose hits he can spend 10% of the test testing us on... =(

 

[Leafie]

Hi med-people, how did the cardio-respiratory exam go? You guys are half way thru exams right? Good luck for the rest!!!!

 

[Origami.Army]

Are ya talking about the otago dudes? no exam yet for me =]

 

[dip]

Are ya talking about the otago dudes? no exam yet for me =]

I think he's talking bout the MBChB chaps, Sir Zheng

 

[g.walker]

is it me or does counter-current flow make no sense at all?

 

[hamlock]

What do you mean? Remember the fish lung example in AS/A of counter current flow? It's the same idea.

 

[g.walker]

never took that analogy, care to explain? seriously ive seen every video on youtube and read the whole wikipedia article and i still dont get it

-_-

You consume 1L of water over a 15 minute . In the space below, draw a flow diagram describing the renal and hormonal response that lead to an increase in urine production.

Would you talk about angiotensin II, ADH, ANP and other regulation of GFR?

 

[hamlock]

Damn, I need a diagram.

100 200 300 (mOsm/L of tubular fluid)
_____________
_____________--> Descending Loop of Henle

50 150 250 (mOsm/L of tubular fluid)
_____________
_____________<-- Ascending Loop of Henle

That's basically what's happening in the loops of Henle. So this means that due to the osmotic gradient between the two tubes, fluid will exit the descending loop into the interstitial space, all along the tubes as long as it's permeable.

If on the other hand we do not have counter current flow and the flow goes in the same direction,


100 200 300 (mOsm/L of tubular fluid)
_____________
_____________--> Descending Loop of Henle

50 250 300 (mOsm/L of tubular fluid)
_____________
_____________--> Ascending Loop of Henle

Then nothing is really happening. If at the start of the ascending loop you have a lower osmolarity, then water will move into the descending loop right? But that would increase the osmolarity downstream in the ascending loop, so that fluid would move into the ascending from the descending. So instead of more fluid being absorbed, it's just being circulated around.


Erm, does that make sense?

@dowhatyousee, talk about all of them

 

[g.walker]

Makes abit more sense, thanks for the effort

but here's what i dont get, you know when the kindeys are producing concentrated urine, if the urea is constantly being recycled, how is it excreted?
