    Peak when your 'friend' has no life.... that's not something I didn't already know mate XD

    But seriously nadzii, we are supposed to be analysing the thread for predictions not making immature comments.... I'm so disappointed in you.

    EDIT: don't ever call me sumayzii in real life. It's retch worthy

    I found it quite easy really, it was quite a bargain only revising teacher predictions but i certainly have exceeded my expectations by 6600%

    Just realised that at no point in the specification does it say that we need to know the blood clotting cascade :facepalm:
    It does say that we need to know about primary non-specific defences against pathogens in animals, 'to include skin, blood clotting,wound repair, inflammation, expulsive reflexes andmucous membranes', so we probably do need to know about the blood clotting cascade.

    I don't know if that's good news or not, but yeah

    Ah, but i don't really know much about the rest of those in detail
    So it's probably not going to be on there, but i would love for it to be a 6 marker, i'd probably be the only one though :lol:

    What are the steps for blood clotting? This always confuses me so much 😭 why couldn't we just stick to fibrin/fibrinogen stuff?!

    When the blood vessel is damaged, it exposes collagen fibres. These collagen fibres activate platelets which produce (as well as the damaged cells) thromboplastin, which is a clotting agent.
    Thromboplastin, in the presence of calcium ions and vitamin K (i think) converts the protein prothrombin into the enzyme thrombin.
    thrombin catalyses the conversion of the soluble fibrinogen into the insoluble fibrin.

    The fibrin forms a mesh which traps red blood cells which is the initial clot. Once the copy has dried out, it becomes a scab, which, as it dries, pulls the edges of the wound together. Once the scab had completely died out it will fall off.

    There's also some stuff about stem cells going to the mesh and differentiating into other cells i think.

    I hope this helps

    Does anyone know how much detail we need to know about open circulator systems in insects? The textbook goes on about stuff like peristalsis, not sure if that's relevant...
