How is oxygen and carbon dioxide transported in human beings?


  • In human beings, transportation of substances occurs via blood
  • The oxygen taken in from the air reaches the alveoli of the lungs from where it diffuses in the bloodstream via blood capillaries surrounding the alveoli. From there, it moves to various parts of the body. 
  • Carbon dioxide is brought back to the lungs via the bloodstream to have it diffused back into the alveoli of the lungs, from where it is exhaled out.
