1. True! The heart has four chambers: two atria and two ventricles, working together like a well-oiled machine to pump blood throughout your body. 2. False! Heart valves are more like bouncers at a club, ensuring blood flows in one direction only – preventing any backflow and keeping the dance going smoothly! 3. True! The right side of the heart is like a delivery service, sending deoxygenated blood to the lungs to pick up fresh oxygen and drop off carbon dioxide. 4. True! The blood that enters the top right chamber, called the right atrium, is rich in carbon dioxide and waste from the body’s cells, ready to be sent to the lungs for cleaning.
