Living organisms must respire because their cells need the energy created by aerobic respiration to assist with life processes the enable them to survive and reproduce. For aerobic respiration to happen a physical process must take place called gas exchange. Gas exchange is when an living organism takes oxygen from the air and diffuses it into the blood, while at the same time removing waste carbon dioxide from the blood.
For gas exchange to occur efficiently all respiratory systems of a living organism must…
Have a large surface area to increasing the efficiency of diffusion of gases allowing more particles to diffuse at any one time
Remain moist to allow efficient gas exchange.
Have thin walls, sometimes as thin as one cell thick, this is
