What organs make up the cardio-respiratory organs?

The cardio-respiratory organs primarily include the heart, lungs, and the associated blood vessels. The heart pumps blood throughout the body, while the lungs facilitate the exchange of oxygen and carbon dioxide. Additionally, the blood vessels, including arteries, veins, and capillaries, transport oxygen-rich and oxygen-poor blood between the heart, lungs, and other tissues. Together, these organs work to deliver oxygen to the body's cells and remove carbon dioxide.
