Carina of Trachea
The Carina of Trachea (pronounced: kə-ˈrī-nə of ˈtrā-kē-ə) is a significant anatomical structure within the respiratory system.
Etymology
The term "Carina" is derived from the Latin word 'carina', which means 'keel of a ship'. This is due to the resemblance of the structure to the keel of a ship. The term "Trachea" is derived from the Ancient Greek word 'tracheia', meaning 'rough', referring to the rough cartilaginous wall of the trachea.
Definition
