-job is to pump blood around the body (delivers nutrients to cells and remove waste)
-Made of 4 muscular chambers (2atria, 2 ventricles)
-Atria pumps blood to ventricles, ventricles pumps blood out of the heart (right to lungs, left to body)

-Left ventricle has a thicker muscular wall then right ventricle, therefore has stronger contractions, so can generate pressure and pump blood further around the body
