The Respiratory System
Scientists: Saskia and MeganOrgans of the respiratory
system:
The function of this part of the system is to filter and moisten
the air coming into the body Nasal cavity-
Pharynx:Here is where the trachea which is the wind pipe and the
food pipe separate. There is a small flap of cartilage called the
epiglottis which prevents food from entering the trachea.
Larynx-This is also called the voice box where the body
generates sound. This also protects the trachea.
Trachea-This is a tube that carries air from the throat to the
lungs. The trachea is covered in tiny hairs called cilia and dust
is removed by coughing.
Bronchi and BronchiolesThe two tubes that the trachea divides
into is called the bronchi, they both enter the lung. The bronchi
spilt into even smaller branches known as bronchiole.
BronchioleBronchi
Alveoli-The alveoli are tiny sacks. The oxygen gas is exchanged
for carbon dioxide gas inside each of these tiny sacks.
Diseases: Pleurisy- a disease when your pleura are enflamed. The
pleura are the outside lining of the lung. It causes a sharp pain
in your chest when you breath in. Bronchitis- accrues when your
bronchi are enflamed. It is a chronic disease but can be
treated.
How to keep the system healthy:Eat healthy.Have fresh plants in
your house and garden.Do exercise that leaves you breathless.Do not
smoke!
