The left lung shares its space with the heart, which it accommodates in the cardiac notch. The right lung consists of 3 lobes (upper, middle, lower), while the left lung consists of 2 lobes (upper, lower) and the lingula, a structure that is homologous to the middle lobe of the right lung. Gas exchange takes place in the alveoli of the lungs. Hyaline cartilage in the form of C-shaped rings ( trachea) and plates ( bronchi) provides structural protection and integrity. The entire respiratory tract down to the bronchioles is covered in ciliated epithelium, which provides immunologic protection by helping clear the airways of dust and microorganisms. The respiratory system is furthermore divided into an upper tract (structures from the larynx upwards) and a lower tract (structures below the larynx). The conducting zone is composed of nonrespiratory tissue and provides the passage for ventilation of the respiratory zone, where the O 2 and CO 2 exchange takes place. ![]() The respiratory system consists of a conducting zone ( anatomic dead space i.e., the airways of the mouth, nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles) and a respiratory zone ( lung parenchyma i.e., respiratory bronchioles, alveolar ducts, alveolar sacs).

The Forges et Chantiers de la Méditerranée (FCM), located at Toulon, had some previous experience with tank production as it had constructed the ten giant Char 2C tanks in 1921 and had been involved in the development of the Char B1. In the end three of the competing prototypes would be taken into production: the Hotchkiss H35, the Renault R35 and the FCM 36. In reaction to this proposal the French Army invited the whole of French industry to offer alternative designs. In 1933 the Hotchkiss company proposed to build a cheap mass-produced light infantry tank. It had a crew of two and was equipped with a short 37 mm main armament and a 7.5 mm coaxial machine gun. The FCM 36 or Char léger Modèle 1936 FCM, was a light infantry tank that was designed for the French Army prior to World War II. ![]() Dragons come in 10 distinct classes the highest one being class 10.
