The respiratory and circulatory systems are made up of organs that work together to deliver oxygen to the rest of the body. These organ systems also work together to release carbon dioxide that is produced as a waste product when the cells of the body perform cellular respiration.
Oxygen is inhaled through the mouth and nose, and carbon dioxide is exhaled. Red blood cells deliver oxygen and remove carbon dioxide through blood vessels, such as arteries, veins, and capillaries.
The diagram shows the respiratory system and the circulatory system.
Arteries, veins, and capillaries are shown. The arteries carry oxygen-rich blood. The veins carry oxygen-poor blood. The capillaries connect the arteries and veins to the lungs and body tissue.
Multiple Choice Question

B.
They supply the body with food to break down during the process of cellular respiration.
C.
They supply the body with carbon dioxide and remove oxygen as waste.
D.
