Blood circulation pathway

The blood circulation pathway encompasses the movement of blood through the cardiovascular system, which includes the heart, arteries, capillaries, veins, and associated regulatory mechanisms. The pulmonary circuit exchanges blood between the heart and lungs for oxygenation, while the systemic circuit delivers oxygenated blood to tissues and returns deoxygenated blood to the heart. Specialized routes, such as coronary, cerebral, and renal circulations, support organ-specific needs. The pathway ensures tissue oxygenation, nutrient delivery, and waste removal, and is critically regulated via vascular tone, cardiac function, and molecular signaling processes[5][7].
