 Endotracheal Intubation |
Is a medical procedure in which a tube is placed into the windpipe (trachea) through the mouth or nose. In most emergency situations it is placed through the mouth.
|
 Tracheostomy |
An incision in the windpipe made to relieve an obstruction to breathing.
|
 Primary Bronchi |
Is an airway in the respiratory tract that conducts air into the lungs. There is a left & right bronchus.
|
|
Secondary Bronchi
|
Continue to branch forming tertiary bronchi and small bronchioles.
|
 Bronchial Tree |
The branching system of bronchi and bronchioles conducting air from the windpipe into the lungs.
|
 Alveolar Ducts |
Are microscopic passages beyond the respiratory bronchioles, from which the alveolar sacs and alveoli arise. Alveolar ducts end with alveolar sacs like a bunch of grapes.
|
 Cartilaginous Rings of Trachea |
Also known as tracheal cartilages. The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.
|
|
Adventitia
|
Is the outermost connective tissue covering of the trachea.
|
 Tracheal Mucosa |
Is the innermost layer and consists of ciliated pseudostratified columnar epithelium with many goblet cells. Goblet cells produce sticky mucus to coat the inner lining of the trachea and catch any debris
|
|
Hyaline Cartilage (Tracheal Ring)
|
Wraps around the trachea (which are not continuous - rather they are C-shaped with a gap ... It is made of hyaline cartilage, and so can become calcified or even ossified, particularly in old age.
|
 Annular Tracheal Ligament |
The annular ligaments of the trachea help hold the trachea together between the C ring hyaline cartilages. They are visible as the pink, thinner areas of the trachea between the whiter, thicker rings (the hyaline cartilages)
|
 Respiratory Membrane |
Is made of the alveolar epithelial cell and the pulmonary capillary endothelial cell, and this structure helps exchange the gases of carbon dioxide and oxygen.
|
 Alveolar Epithelium |
Or pneumocytes, are cells lining the alveoli of the lungs.
|
 Type 1 Alveolar Cells |
Are squamous (giving more surface area to each cell) and cover approximately 90–95% of the alveolar surface. These cells are involved in the process of gas exchange between the alveoli & blood.
|
 Type 2 Alveolar Cells |
Cover a small fraction of the alveolar surface area. Their function is of major importance in the secretion of pulmonary surfactant, which decreases the surface tension within the alveoli.
