Kind of breathing apparatus

ü. Nasal Cavity (cavum Bucalis)
ü. pharynx (throat Jetty)
ü. The trachea (windpipe)
ü. bronchus (Branch Throat)
ü. bronchioles (branch of the bronchus)
ü. alveoli

Nasal cavity

• Breathing should be through the nasal cavity. The air is inhaled through the nose had three treatments as follows:
• First, the air is filtered by the nose hair and mucous membranes.
• Second, the air having a temperature adjustment.
• Third, in the nose set the moisture in the air.

The base of the throat (larynx)

• Before entering the larynx, pharynx air through first.
• The larynx has a lid called the epiglottis.
• The larynx also produces sound when air blows from the lungs.

Rod throat (trachea)

• From the larynx, air enters the trachea (windpipe).
• The wall next to the throat, covered with a mucous membrane that her hair cells that vibrate like a nose hair.

Bronchi and bronchioles

• bronchus is branching trachea.
• bronchial branch is the son of suffering bronchial branching according to the number of lung gelambir.
• The lungs are the right 3 branching, while the left lung two branching

Lung (Pulmo)

• The lungs are located inside the chest cavity above the diaphragm.
• The lungs are covered by a lining of the lungs called the pleura.
• In the lungs are the organs that allow the exchange of air (O2 and CO2) is the alveolus.

    BREATH CHEST

Ø Inspiration: When the muscles between the ribs contract, the ribs membesar.akibatnya chest lifted so that the volume of air pressure in the lungs decreases, outside air srhingga a greater pressure into the lungs.

A. Expiration: When the muscles between the ribs relax the rib cage so that the chest cavity mengecil.akibatnya depressed, air pressure in the lungs expand, so the air out.
