Epithelial Tissues
Pseudostratified Epithelium
The majority of respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium. Ciliated pseudostraified columnar epithelium can be found in the lines of the trachea as well as the upper respiratory tract.
As mentioned earlier, the majority of respiratory passageways are lined by pseudostraified columnar epithelium contain a ciliated epithelial cell.
Ciala are tiny hair like structures located on the surface of certain cells. When it comes to the functioning of cilia in the ciliated epithelial cell it is able to sweep mucus and dust where it would carry up to the bronchi and trachea toward the pharynx, where it can be swallowed or result in an individual to sneeze.
Muscle Tissues
A set of muscle tissues surround the lungs which have the ability to cause air to be inhaled or exhaled from the lungs. The main muscle of respiration in the human body is the diaphragm, a thin sheet of skeletal muscle that forms the floor of the thorax (The Circulatory and Respiratory System).
Between the ribs there are many small intercostal muscles that assist the diaphragm with expanding and compressing the lungs (The Circulatory and Respiratory System).
These muscles can be broken down into two groups: internal intercostal muscles and external intercostal muscles. Internal intercostal muscles function to depress the ribs in order to compress the thoracic cavity (the cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck containing the lungs and heart (The Free Dictionary: Thoracic Cavity)) and force air to be exhaled from the lungs. The external intercostal muscles function to elevate the ribs, expanding the volume of the thoracic cavity and causing air to be inhaled into the lungs (The Circulatory and Respiratory System).
