I also had J (skin) and F (mucous membrane) for this question
Do you think OCR made a mistake by the MarkScheme having J and I(platelets) instead ?
They’re claiming platelets are physical barriers ?

I think it’s that platelets help to form a physical barrier (scab) but I’m not a huge fan of the wording of the question
