RESPIRATORY SYSTEM
Breathing- is the process that
delivers oxygen to where it is needed in the body and removes carbon dioxide.
All animals need oxygen to live. Land animals get
oxygen from the air. We breathe in to allow oxygen to move into our bloodstream and we breathe
out to remove carbon dioxide from our blood. The oxygen is carried in the blood to all cells of the
body. And did you know that the air we breathe out has 100 times more carbon dioxide than the
oxygen we breathe in.
Air flows into your body through the nose or mouth and enters a specific
pathway for air. These pathways carry air into our lungs. Then these split off where
they become smaller and smaller. In the end, the pathways are attached to small air
sacs where the exchange of oxygen from the air for carbon dioxide occurs.
PARTS AND FUNCTION
• The human respiratory system
is composed of the nasal
cavity, pharynx, larynx, trachea,
bronchi, and lungs. It is liable
for the method of respiration
that's vital to the survival of
living beings.

between your ribs. When you breathe out (exhale), your diaphragm relaxes and moves
upward into the chest cavity. The intercostal muscles also relax to decrease

dioxide is pushed out of your lungs and windpipe, and then out of your nose or
mouth.
