Respiration occurs in the cells of the body.In humans the
respiratory system transports oxygen from the air to the
blood stream where it can be taken to the cells.the proces
of taking in oxygen and given out carbon dioxide may be
called EXTERNAL RESPIRITION.The chemical process of oxygen
with food [glucose]to release energy is called tissue
raespiration.during inhalation, the chet rises and the ribs
move up and out,when the oxygen gets into the blood cells
it is picked by the red blood cells throug the capillaries
around them the oxygen is then transported to the tissues
of the chemical breakdown.The hairs in our nose trap the
dirt and prevent them fromentering the lungs.the mucus
traps dirt and germs and the hair waft thethe mucus into th
throat to be swallowed.The air we breathe out is warmer
than the one we breathe in.Fatty acids can also be oxidiced
to release energy.
