How do the lungs and heart transports in the cardiorespiratory ststem?

The lungs and heart work together in the cardiorespiratory system to facilitate the exchange of oxygen and carbon dioxide. When we inhale, oxygen enters the lungs and diffuses into the bloodstream through the alveoli. The heart then pumps this oxygen-rich blood to the body's tissues, while simultaneously returning carbon dioxide-laden blood from the body back to the lungs for exhalation. This continuous cycle supports cellular respiration and maintains overall respiratory and circulatory function.
