Bowel-GI - Esophagus Swallowing
Caption
In the center of the screen we see the trachea in transverse view with its round hyperechoic cartilaginous rings. To the right of the trachea is the smaller, collapsed, muscular walled esophagus which moves as the patient swallows in this clip. We can also see the pulsatile carotid arteries bilaterally at the edges of the screen.
