Do you think your heart plays the biggest role in the process of getting your blood become rich in oxygen and transporting materials gases and other molecules to and from the different parts of the body? WHY DO YOU THINK SO?​

Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.

Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.

So, heart actually helps us indirectly in many ways.
