Is it true that in the human heart, oxygenated blood flows through the right side and carbon dioxide-rich blood flows through the left side?

In the human heart, oxygenated blood flows through the left side and carbon dioxide-rich blood flows through the right side. The left side of the heart receives oxygenated blood from the lungs and pumps it out to the rest of the body, while the right side of the heart receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The heart is divided into left and right sides by a muscular wall called the septum, which prevents oxygenated and deoxygenated blood from mixing.
