What is "windpipe"?

The windpipe, also known as the trachea, is a vital part of the human respiratory system. It is a flexible tube that connects the throat (pharynx) to the bronchi in the lungs. The windpipe provides a pathway for air to enter and exit the lungs during breathing. It is made up of rings of cartilage, which help maintain its structure and prevent collapse. The inner lining of the windpipe contains specialized cells that produce mucus, helping to trap and remove foreign particles and bacteria. The windpipe plays a crucial role in facilitating the exchange of oxygen and carbon dioxide in the respiratory process, allowing for efficient respiration and oxygenation of the body.
