Which of the following encompasses both the circulatory and respiratory systems?

The cardiorespiratory system refers to the integrated function of the circulatory and respiratory systems working together to supply oxygen to the body and remove carbon dioxide. This system plays a vital role in maintaining homeostasis and supporting cellular metabolism and energy production through the exchange of gases. The circulatory system, consisting primarily of the heart and blood vessels, is responsible for transporting blood, nutrients, and gases throughout the body. Concurrently, the respiratory system, which includes the lungs and air passages, facilitates the exchange of oxygen and carbon dioxide during the breathing process.

Other systems listed, such as the cardiovascular system, refer specifically to the heart and blood vessels, thus excluding the respiratory components. The musculoskeletal system involves bones and muscles that support the body and enable movement, while the nervous system manages communication and control within the body. Consequently, the term that accurately captures the interplay between both the circulatory and respiratory systems is the cardiorespiratory system.
