your body is important because if you didn’t have lungs you would be dead. or a heart to keep your blood keep flowing you would still be dead. IF YOU DIDN’T HAVE ANY OF THAT YOU WOULD BE DEAD NO EXEPTIONS.
first things first you breath through either you nostril or mouth to your lungs to your bronicules. then the oxygen through you bronicules to your heart. then inside your heart is these things called a left and right ventricles and atrium. first the oxygen goes through the right ventricle then the right atrium. then the carbon goes through the left atrium, ventricle. then carbon and waste goes through veins to capillars then they divide into more blood vessels.
