The correct answer is:
C. Blood transports oxygen from the lungs to other organs.
The cardiovascular system (which includes the heart and blood vessels) and the respiratory system (which includes the lungs and airways) work together to supply oxygen to the body and remove carbon dioxide. The respiratory system allows oxygen to enter the lungs, where it then diffuses into the blood. The cardiovascular system then transports this oxygen-rich blood to various organs and tissues throughout the body.
