The respiratory system brings oxygen into the lungs and removes carbon dioxide. Oxygen diffuses across the alveoli into blood, where hemoglobin carries it. The circulatory system (heart and blood vessels) then pumps that oxygenated blood to body tissues and brings carbon dioxide-rich blood back to the lungs to be exhaled. Together they deliver O2 to cells, remove CO2, and help maintain pH and homeostasis.
