Answer
Respiratory and circulatory system work close together with alveoli to provide oxygen to cell.
Explanation
Through the process of respiration when oxygen reaches to lungs and then to alveoli. Here oxygen is diffuse to blood through capillaries by the process of partial pressure diffusion. Oxygen combine with hemoglobin present in red blood cells. Now with the help of circulatory system this oxygen is transported to all other parts of the body where needed.
