Windpipe
Windpipe
The Windpipe (pronounced: /ˈwɪndˌpaɪp/), also known as the Trachea, is a vital part of the respiratory system in humans and many other animals.
Etymology
The term "windpipe" is derived from the Old English 'windpype' which literally means 'pipe for breathing'. The scientific term, "trachea", is derived from the Ancient Greek trācheia artēria, meaning 'rough artery'.
Definition
The windpipe is a tube-like structure 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.
Structure
The windpipe is approximately 10-12 cm long and 2 cm in diameter. It is composed of about 15-20 C-shaped rings of hyaline cartilage. These rings are open in the back and connected by smooth muscle (the trachealis muscle) and flexible tissue which allow the trachea to constrict and expand during breathing.
Function
The primary function of the windpipe is to provide a clear path for air to enter and exit the lungs. The mucus lining the trachea traps dust and other particles that could be harmful to the lungs, while the cilia move this mucus upward and out of the lungs, helping to keep them clean and clear.
