The cardio-respiratory system consists of the cardio vascular system (heart and blood vessels) together with respiratory system (lungs and air ways). These systems work to transport oxygen to the muscles and organs of the body and remove waste products including carbon dioxide.
The left side of your heart pumps oxygenated blood to your body.
The right side pumps blood to the lungs to receive the oxygen and it goes out of the left side to distribute it throughout the body.
Hope this helps! If you have any questions, just ask!
