From where does the trachea extend?

The trachea extends from the larynx to the primary bronchi, which is an essential part of the respiratory system. The larynx serves as a passage for air entering the lungs and plays a crucial role in protecting the airway during swallowing. The trachea, often referred to as the windpipe, is a tube-like structure that allows air to flow to and from the lungs. After the trachea bifurcates, it divides into the right and left primary bronchi that lead into each lung. This understanding is fundamental for anyone involved in cardiovascular perfusion since the efficient exchange of gases, which is critical during procedures requiring cardiopulmonary support, depends on the integrity of this pathway.
