The circulatory and respiratory systems work closely together to ensure that oxygen is delivered to tissues and carbon dioxide is removed from them. In the lungs (part of the respiratory system), oxygen is exchanged for carbon dioxide in the alveoli, where blood from the surrounding capillaries picks up the oxygen and releases carbon dioxide. This oxygen-rich blood is then transported by the heart (part of the circulatory system) to the rest of the body, sustaining cellular respiration and overall metabolic functions.
In 3 sentences, summarize the interactions between the circulatory and respiratory systems.
Make sure to include at least one organ from each system in your answer and explain the outcome of the interaction.
