Trivia: How many chambers does the heart have?

4

10
The correct answer is 4
So why is this answer correct? : The heart is divided into four chambers. The upper chambers are the left atrium and right atrium, and the lower chambers are the left ventricle and right ventricle. The right chambers pump blood to the lungs to receive oxygen, and the oxygenated blood is then sent to the left side of the heart, which distributes it to the rest of the body. Oxygen-poor blood is then returned to the right chambers to start the process again.
