b. heart
c. lungs

Explanation:

Blood is the medium in the circulatory system that transports oxygen (bound to hemoglobin in red blood cells), removes waste materials (like carbon dioxide, urea etc.), and carries nutrients (glucose, amino - acids etc.) to different parts of the body. Lungs are involved in gas exchange (taking in oxygen and releasing carbon dioxide), the heart is the pump that circulates the blood, and arteries are blood vessels that carry blood away from the heart.

D. blood
