The Bloody Circuit

The Bloody Circuit refers to the pathway blood takes from the heart to the lungs and back. It starts when the heart pumps deoxygenated blood to the lungs via arteries. In the lungs, blood releases carbon dioxide and picks up oxygen. The oxygen-rich blood then returns to the heart through veins, completing the circuit. This process is essential because it supplies the body with oxygen needed for energy and removes waste gases. The term emphasizes the "circulating" process that keeps blood continuously moving through the lungs, ensuring proper oxygenation and overall health.
