Blood flow in the heart and lung
The pulmonary circulation involves a complex interaction between the heart and lungs. Blood flows from the right ventricle through pulmonary arteries to reach the lungs’ alveoli, where vital gas exchange occurs.
The oxygenated blood from the lungs returns to the left heart chambers through pulmonary veins. This refreshed blood carries essential oxygen required for cellular metabolism throughout the body.
In the systemic circulation, the left ventricle pumps oxygen-rich blood through the aorta to all body tissues. This distribution ensures proper organ function and cellular respiration.

The deoxygenated blood returns to the right atrium through venae cavae, completing the circuit. This continuous cycle maintains tissue oxygenation and removes metabolic waste products.
Modern medical science emphasizes the importance of maintaining healthy heart-lung circulation. Regular cardiovascular exercise and proper nutrition support optimal circulatory function.
Understanding this intricate system helps healthcare providers diagnose and treat cardiopulmonary conditions effectively. Regular monitoring of heart and lung function ensures early detection of potential issues.
