Abstract
The heart is probably one of the most important muscles in an organism's body. It is what drives the flow of nutrients, oxygen, and other vital cells across an organism's body. In different organisms the heart can have slightly different anatomical features as compared to other organisms. In humans, the heart is divided into 4 chambers; the left and right atriums as well as the left and right ventricles. Each chamber is separated by muscle walls and by special valves, the semi lunar and cuspids, which allow blood to flow into appropriate chambers and to make sure oxygenated blood and deoxygenated blood do not mix, allowing for 100% separation.
