Does anybody have any idea about this?

U mean for the question where u had to say the difference in blood between the artery and vein.

I think u need to say that vein oxygenated while artery deoxygenated

okay, i think i lost my marks on the following:

1 mark on 6 marker
5 marks on the last four pages
3 marks on things like volume, marathon person and something else
3 marks stupid mistakes

which gives me around 48/49 :wink:

How cann you even guess what your mark is?? the mark scheme is hardly lenient!!

I think saying either should get u the marks, right?

Yeah that one.. The thing is I think they had a 1 mark question about composition of blood in the vein and then another 2-3 mark question following on from that idea? So if I got that first mark wrong (because I said artery is oxygenated) would I get the other 3 marks wrong as well..

I had originally but oxygen but the question specified constitution of blood so I changed it to C02 because you still have r.b.c.s

If this was one of the first questions with the lungs I said that the artery has a more elastic wall....

The bit about stents talks about the coronary artery.

I've checked like 3 times it just says artery not coronary artery

Yh but it says about constitution of blood. I think oxygenated/deoxygenated blood is good enough to get you the marks

if people give me most of the question and marks, i'll start making the unoffical mark scheme ...

I put when you're hot cappilaries dilate and let blood closer to surface to radiate heat
and when cooler they shrink so less blood to surace.
Also the marathon people I said abou the sweat being able to evaporate on a dry day but not on a umid day (basically P1 Physics)....
