Ever wondered how your heart keeps you alive and kicking? It's all about the amazing journey of blood flow! Think of your heart as a highly efficient, two-sided pump. Deoxygenated blood, returning from your body, enters the right atrium. From there, it flows through the tricuspid valve into the right ventricle.
The right ventricle pumps this blood through the pulmonary valve into the pulmonary artery, taking it to the lungs to pick up oxygen. Now oxygen-rich, the blood travels back to the heart via the pulmonary veins, entering the left atrium. It then flows through the mitral valve into the left ventricle.
Finally, the powerful left ventricle pumps the oxygenated blood through the aortic valve and into the aorta, the body's main artery. From there, it's distributed to every corner of your body, delivering vital oxygen and nutrients. This continuous cycle, happening every second, ensures your tissues stay healthy and you stay energized! It's truly a remarkable feat of natural engineering.
