The trachealis muscle is a smooth muscle that bridges the gap between the free ends of C-shaped cartilages at the posterior border of the trachea, adjacent to the esophagus. The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force e.g. during coughing.
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.The trachea's rigidity is maintained by a series of cartilaginous rings arranged along its length called C-shaped cartilage rings.hese cartilage rings are C-shaped to provide room for your esophagus, which lies along the backside of your trachea. The gaps between the cartilage rings are bridged by a tough elastic membrane. The trachea is very resistant to compression, but it is capable of stretching lengthwise.
