    Atherosclerosis is the name for a condition that occurs when plaques form on the inner lining of the blood vessels. It is composed of fatty material which accumulates and can become calcified. Atherosclerosis forms in muscular arteries and the aorta.


    A thrombus is the name for a blood clot that forms on the inner lining of your blood vessels-most commonly the deep legs veins.

    How do you define an isotonic, hypotonic and hypertonic solution?Also, 'protein carriers' and 'protein channels', what's the difference between them? and which one is assigned for facilitated diffusion and which one is for active transport?

    Ok
    -made up of glucose joined by glycosdic bonds via condensation reactions.
    -2 molecules amylose and amylopectin
    -amylose 1-4 glycosdic bonds and spirals(straight chain)
    -amylopectin 1-6 and 1-4 glycosidic bonds( branches)

    Out of the top of my head think it should get 5 tho :P

    I got a question...
    The elastic fibres (in the aorta) stretch so that they can accommodate the greater volume of blood without being damaged. Between surges, these elastic fibres return to their original length, thus squeezing the blood and moving it in a continuous flow. This is known as elastic recoil.Alright, but does this elastic recoil raise or lower the blood pressure? If not, does it have any other role other than allowing the blood to move in a continuous flow?
    Well, I think the elastic recoil helps to maintain its pressure. If you look at this graph (dotted line is arterial pressure), you can see that AP starts to fall, but then rises again before it continues to fall. I believe that this is due to the elastic recoil of the arterial walls

    The term protein carrier is generally used to refer to those that actively transport the substance/molecule, and protein channel for those that do not i.e. simply allow (facilitated) diffusion.
