The heart is responsible for moving blood throughout our body. The chief function of blood is to bring oxygen and nutrients to tissues in the body, and to carry away carbon-dioxide, lactic acid and other waste material.

Here is an analogy - a truck carrying food (oxygenated blood for left side of heart) is transported and makes several stops to deliver its food to various stores (your organs, cells). In turn it pickups the waste left from the used food (de-oxygenated blood) from these stores and exchanges it for new food (de-oxygenated blood gets pushed to the lungs and is exchanged for oxygenated blood) and the process repeats itself.
