The two systems working together are

• Digestive & Circulatory

• Respiratory & Circulatory

• Nervous & Respiratory

• Circulatory &. Muscular

Blood vessels carry red blood cells to the lungs, to get rid of carbon dioxide and pick up oxygen that has been breathed in. The heart pumps red blood cells carrying oxygen from lungs to all cells in the body and back to the lungs once the oxygen has been used up.
