The separation of the right and left sides of the heart is crucial for maintaining the efficiency of the circulatory system. The right side deals with deoxygenated blood returning from the body, pumping it to the lungs for oxygenation. Meanwhile, the left side receives oxygenated blood from the lungs and propels it throughout the body. This segregation prevents the mixing of oxygenated and deoxygenated blood, ensuring that tissues receive a continuous supply of oxygen while efficiently expelling carbon dioxide. The distinct functions of the right and left sides optimize the heart’s performance, supporting the body’s oxygenation and metabolic needs.
