MT 30 LAB – H 4 years, 5 months ago Good evening everyone!
The sublarynx, larynx, and supralarynx are the three sections of this organ. It is made up of nine cartilages that are joined by muscles and ligaments.
2. The lungs take in air and transport oxygen. It is then distributed throughout the rest of the body.
The organ seeks support from the body’s surrounding tissues.
The organ needs support from the diaphragm muscle, the intercostal muscles between the ribs, the abdominal muscles, and sometimes even the neck muscles.
3. The trachea, at the fifth thoracic vertebra, separates into right and left bronchi, sending air to the right or left lung. The hyaline cartilage on the tracheal wall provides stability and prevents it from collapsing. The epithelium that lines the trachea is the ciliated pseudostratified columnar, comparable to that found in the nasal cavity and nasopharynx. The cilia move the mucus upward, where it is either ingested or discharged, and the goblet cells generate mucus that captures germs.
