The Trachea, or windpipe, is a vital fibrocartilaginous tube that serves as the initial segment of the lower respiratory tract. It is supported by 16-20 C-shaped rings of hyaline cartilage, which prevent collapse, and features a smooth muscle band called the trachealis that allows for oesophagal expansion.
