Breathing mechanism
Inhalation
Exhalation
Oxygen is taken into the body by inhalation and travels to cell for cellular respiration
Carbon dioxide is exhaled out so that blood can carry more oxygen.
Nasal cavity
Pharynx
Larynx
Trachea
Bronchi
Bronchiole
Alveoli
Inside there is mucus to humidify air, and capillaries warm the air, hair hold up the particles from the air.
It is a muscular structure
It is a tube shape that passes the air through lungs
It has a C shape cartilage to give a shape to trachea. It is also a tube shape that has muscles and fibers to pass the air to lungs. It has cilia that face upwards so that they hold the particle from going to lungs when we breathe from mouth.
The branches of trachea going into lung surface.
The sub branches of the bronchi.
The end of the bronchiole system that have capillaries to exchange O2 and CO2. The alveoli provide surface area increase.
Breathing in
Breathing out
Rib cage muscles contract and diaphragm contracts and moves down. Volume in the lungs increases, air pressure drops during inhalation.
Rib cage muscles relax and diaphragm relaxes and moves up. Air volume in the lungs decrease and pressure increase so that we can breathe out.
