Today at Chalkdust, we’re celebrating our love for mathematics, and what better way to do that than by analysing our heartbeats? The heart is composed of four main chambers: two atria at the top and two ventricles at the bottom. Apart from carrying our hopes and dreams, the heart’s main function is to pump blood around our body.
