Answer:

The circulatory and respiratory systems work together to pump blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and the bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart and thats how it works.

The cardiovascular system pumps blood into the lungs to oxygenate, then the respiratory system gives the oxygen rich blood back to the lungs so it can be distributed throughout the body.
