Tracheal
Tracheal
Tracheal (/trəˈkiːəl/), derived from the Greek word tracheia, refers to anything related to the trachea, the large airway that leads from the larynx (the voice box) to the bronchi of the lungs.
Etymology
The term tracheal is derived from the Greek word tracheia, which means "rough". This is in reference to the rough, cartilaginous wall of the trachea.
Anatomy
The trachea, also known as the windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air. It is lined with ciliated cells and mucus-producing goblet cells, which work together to filter, warm, and moisten the air we breathe. The trachea is surrounded by 16-20 C-shaped rings of hyaline cartilage that provide structure and prevent the trachea from collapsing.
