Hi there guys.......this is for a project i am going to be doing for school tomorrow. The topic for my presentation is about the applications of different sciences (bio, chem, physics) and their roles in the causation of a heart attack. But I am having difficulties finding aspects that cause a heart attack, which relates to physics. For example, in terms of biology you can discuss healthy living and how it affects the heart, for chemistry you can talk about some chemicals that lead to the blocking of nerves/veines which leads to a heart attack, etc, but i have no idea how physics can be discussed. I know it is applicable as it is applicable in anything and everything, but I am not too informed about "the heart." Do you guys know what I should look into, in terms of the physics aspects which is associated with the causing of a heart attack? Thanks for any help.
