The respiratory system takes in carbon dioxide, and the circulatory system transports in the body.
The respiratory system takes in oxygen, and the circulatory system transports it in the body.
The respiratory system transports food throughout the body, and the circulatory system rids the body of wastes.

The respiratory system takes in oxygen and removes carbon dioxide from the body. It does this through the process of breathing, where oxygen is inhaled into the lungs and carbon dioxide is exhaled. The circulatory system then works to transport oxygen-rich blood from the lungs to the rest of the body, delivering oxygen to all the cells. At the same time, it collects carbon dioxide waste from the cells and transports it back to the lungs to be exhaled. This exchange of gases is necessary for cells to carry out cellular respiration and produce energy. So, the respiratory system and the circulatory system work together to ensure the body is supplied with oxygen and rid of carbon dioxide waste.
