why are the trachea and esophagus so close in proximity?
What is the structure difference of the esophagus and trachea? The esophagus is a smooth tube that when we eat food goes trough the esophagus to the stomach. The trachea (windpipe) is made of cartilaginous rings that when we inhale/exhaleâ¦ air (breath in and out) it goes to the lungs. So if food goes accidentally to your trachea, you choke.
Lesson Summary. The trachea is an important structure within your respiratory system, which is the organ system that delivers oxygen to your bloodstream. The trachea is a rigid tube that conducts air from your larynx to your bronchi.
