Trachea is bounded by c-shaped ring to provide it support and flexibility
The trachea is a firm cartilaginous tube and is a self supporting structure
They are C-shaped, with the opening in the back so that when you swallow food, the esophagus expands into the area of the trachea to allow the food (called a bolus) to go down. This process is called deglutition. If they were not C-shaped and positioned this way, your food would not be able to go down into your stomach.
The point at which the trachea splits into the right and left mainstem bronchi is called the carina. Hope this helps.
The wind pipe is called a trachea. It brings air from your mouth down into your lungs. It is a straight tube at the top that separates into two branches, one going into each lung. These are the left bronchus and right bronchus.

You have primary cartilaginous joint between the growing bones. They are called as primary cartilaginous joint. You have secondary cartilaginous joint in mid-line of your body. For example pubic symphysis, a joint between manubrium sterni and sternum as well as discs between your vertebrae.
First, the trachea is part of the respiratory system while the esophagus is part of the digestive system of human and some of the animals. Second, the trachea is the tube in air-breathing vertibrates that conducts air from the throat to the bronchi. It is commonly called windpipe and is made up of numerous cartilaginous half rings which is adjacent to the esophagus. Lying in front of the esophagus. While esophagus, a mascular tube about 10 inches long passes behind the trachea and the heart. The passage down which food moves between the throat and the stomach. In short, trachea is where the air passes while esophagus is where the food passes.
