In the trachea, the cartilaginous rings are U-shaped. They are open on one side to allow movement of*1 pointthe larynxthe esophagusthe diaphragmthe lungs
Solution
The cartilaginous rings in the trachea are indeed U-shaped. They are open on one side to allow movement of the esophagus. This is because the trachea and esophagus are located next to each other in the body. When we swallow food, the esophagus expands. The U-shape of the tracheal rings allows them to accommodate this expansion.
