Respiration
Is the taking in of air or breathing in.
Inspiration
Is the breathing out or the expelling air from the lungs.
Expiration
Is a hollow tube about 4.5 inches in length extending from the Larynx to the Bronchi below.
It commences opposite the sixth cervical vertebra (C6) and extends down to the fourth dorsal body (T4).
Trachea/Windpipe
Is the panty-like structure on the bifurcation of the two bronchi.
Carina/Keel
Are the final minute tubes and are continuous with the air spaces of the lungs.
BRONCHIOLES / LITTLE BRONCHI
Are the organs of respiration that occupy the (R) and (L) chest
cavities.
Are spongy, crepitant, float on water and have elastic tissue in their walls, frequently blue-gray in color because of inhaled dusts.
Lungs
The partition between the two halves of the chest. It extends from the base of the neck to the diaphragm.
Mediastinum (Middle Septum)
Natural division that separate the Lobes of the lungs.
Fissure or Grooves
Are small units of each Bronchopulmonary segment containing many minute air sacs.
Lobules (Little Lobes)
Is the active tissue of the lungs.
Parenchyma
Is a depression on the medial surface of each lung where vessel and bronchi enters into the lungs.
Hilum/Hilus
Is its attachment to the mediastinum and is composed of all the structures entering or leaving the lung which includes the pulmonary artery and veins, bronchial arteries and veins, main bronchus, lymph vessels and nodes and nerves.
Lung Root
Is the lining membrane of the chest cavity and the covering membrane of each lung which includes:
Pleura
Parietal & Visceral
