Where does the left side of your heart pump blood to?

The left side of the heart receives blood from the lungs before pumping it through the aorta and out to the rest of your body. This is referred to as the systemic circuit. After the body is nourished and oxygenated, the blood returns to the right side of the heart carrying waste and carbon dioxide to the lungs. This begins the pulmonary circuit that ends when the blood, once again, returns to the left side of the heart.
