How do the respiratory and circulatory systems work together to make gas exchange possible?

Answer:

The respiratory and circulatory systems work together to deliver oxygen to cells and remove carbon dioxide. The respiratory system takes in oxygen-rich air into the alveoli of the lungs. The circulatory system then transports this oxygen from the lungs to the body's cells through the blood. Simultaneously, the circulatory system collects carbon dioxide waste from the cells and carries it back to the lungs, where the respiratory system exhales it from the body.
