    What cells make red blood cell and the location.
    I wrote kupffer cells; location: liver[/QUOTE]

    Kupffer cells break down erythrocytes, not make them.

    That exam was so easy! Ocr please make exams harder so they're actually a challenge, and at least test on stuff which we won't know about lol!

    Said no one ever.

    After that I've waved goodbye to any hopes and dreams I had of a medical career.

    Ps: anyone who is a genius, don't make an unofficial markscheme. It will kill me even more.
    Looool stop overreacting you'll be fine just hope for the best

    well the fluid reaches equilibrium with the body as there is no counter current system, so i think its because not all of the toxic chemicals are removed, in haemo they are all filtered out but in peri it has to be done repeatedly as concentrations decrease steadily. Its basically far less efficient and they lied, its being phased out as they think it might be dangerous!
    yaaaaaaaas i wrote that :')

    Anyone know why peritoneal has to be done 4 times a day and haemodilaysis 3 a week?

    Maybe so toxic products don't build up inside the body?? IDK. I said that a build up of urea makes people feel sick and vomit. I don't know...

    For the insulin continuing to be secreted, I stated that it takes time for the insulin to reduce the glucose concentration, so the mechanism would carry on until the insulin begins to lower the blood glucose concentration.

    Anyone else say this?

    That's exactly what I put because I remember a past paper question where it spoke about b/T lymphocytes requiring atp

    I put that because the body was sweating, the body temperature decreases and so the brain starts the body shivering to increase the temperature. Which is why you constantly feel hot and cold when you have a fever.

    Why is that everyone is getting 93 or somewhere in the 90s ? I got something like 107 I think it was? But it was definitely 3 digits... I did the same procedure with the others and got the answers that were on the grid :/ I hope I got it right

    For the question on why dextrose is added to the dialysis fluid, was the answer to reduce its water potential so that its isotonic with the blood and prevent haemolysis?
    I thought it might be about reducing sugar loss from the surrounding tissue preventing hypoglycemia as the sugar solution is closer to blood/tissue fluid water potential.... but a quick search brought this up

    "Peritoneal dialysis solution contains dextrose (or another sugar), as well as salt and minerals dissolved in water. The dextrose pulls wastes and fluids into the dialysis solution. The solution comes in concentrations of 1.5%, 2.5% and 4.25% dextrose. Higher amounts pull away more waste, which offers immediate and long-term benefits. But over time, the body absorbs dextrose -- and that causes dialysis to become less effective."

    I said how peritoneal fluid thing has to be taken out after 4-6 hours? is this right
    Apparently it had something to do with the fact that the peritoneal fluid doesn't maintain a concentration gradient as it is stationary (unlike the dialysis fluid) so to prevent the waste substances diffusing back in it has to be taken out?

    I didn't write that myself (I got it very wrong) but I've heard it has something to do with that.

    Yeah, I keep telling myself it was only one mark.

    I can't believe how little there was of the actual F214 content though. I was all prepared to be writing 6 markers on the loop of Henle and photophosphorylation!
    Nothing really on Calvin, light dependant, krebs, oxidative phosphorylation, link, liver, kidney, adrenaline, heart. So basically just missed out the whole course really! I think its a joke, they are playing with peoples lives and I did not dedicate myself to revising to be asked something that isn't even in A level Biology!

    Sounds about right actually! Couldn't remember from statistics in AS! I had no idea what to put... I mean they then compared gender on the next question hence why I put value both 😔

    I said so that the potential difference in the cell can be retained but that's probably completely wrong!

    At the end, you sweat when you have a fever and why, then you shiver and why.
