The blood-air barrier in the alveoli is 50 times thinner than a sheet of trace paper. This particular thinness helps faster oxygenation.

Lungs make up the main organs of the respiratory system and facilitate the exchange of gases along with the associated airways and blood vessels. Additionally, different parts of the lungs are also involved in certain non-respiratory features, which includes certain homeostatic things as well as resistant processes.

The right bronchus branches out into three secondary bronchi, and the left bronchus gives rise to 2 extra bronchi. The supplementary bronchi section into tertiary bronchi, which further give rise to bronchioles. Along with the branching, the actual content of hyaline normal cartilage decreases, lowering to be able to none in the bronchioles, that can be a of clean muscle raises.

  • The left lung is somewhat smaller than the right, which is divided into two lobes by an oblique fissure.
  • These two lobes are similar to the superior and inferior lobes of the right lung.

The alveoli tend to be thin-walled, water sacs which have been arranged in groupings. The walls of the alveoli are made up of: i) Type I alveolar cells that make up the architectural base.

Each tertiary bronchi gives rise to distinct respiratory units known as bronchopulmonary sections that have their own set of bronchioles, alveoli, blood vessels, and lymphatic vessels. The trachea, bronchi, and the succeeding divisions make up the airways that help the entry and exit of air from the lungs.


The bacteria Mycoplasma pneumoniae is responsible for producing this disease.

The trachea or windpipe is the major structure that links the nasal as well as common some other primary to the lungs. The trachea bifurcates into primary branches referred to as bronchi, which enter into the two lungs. The bronchi tend to be made up of hyaline cartilage and clean muscles.
