[ The trachea is lined with a moist mucous-membrane layer composed of cells containing small hairlike projections called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous membrane that secrete mucus droplets and water molecules. At the base of the mucous membrane there is a complex network of tissue composed of elastic and collagen fibres that aid in the expansion, contraction, and stability of the tracheal walls. Also in this layer there are numerous blood and lymphatic vessels; the blood vessels control cellular maintenance and heat exchange, while the lymphatic vessels remove the foreign particles collected by the wall's surface. Around the tracheal wall there is a series of 16 to 20 horseshoe-shaped cartilage rings. They encircle the front part of the trachea but are open where the trachea lies next to the esophagus. Here the free ends of the cartilage are connected by muscle bands. Since the cartilage is in individual rings, rather than one continuous sheath, the trachea can stretch and descend with the breathing movements. The cartilage bands are replaced with fibrous scar tissue in advanced age.
Muscle fibres run over and alongside the cartilage, as well as through the mucous membrane. They serve to narrow and shorten the passageway in breathing. They also may contract in cold weather and when smoke, dust, or chemical irritants are in the inhaled air. During coughing, which is a forced exhalation, the muscle bands connecting the free cartilage ends press inward so that the tracheal lumen is about one-sixth of its normal size. Air rushing through this narrow channel travels at high velocities and is thus able to dislodge foreign elements from the trachea.]
Stuff with more stuff with even more stuff.
The walls of the trachea is made up of cartilage.

You are thinking of the trachea, or windpipe, though it is not entirely made of cartilage.
The trachea is made of C shaped rings of cartilage, this maintains the shape of the trachea.
The trachea itself is made of ligaments and cartilage, but there are muscles in the region around the trachea.
It is made up of rings of cartillage

According to a figure in my human biology book if the trachea and the Bronchus is made out of the same matter then the Trachea does enter the lung. Unless the bronchus is made out of unique tissue muscle etc.

i dont no the trachea is located just below the pharynx. when we breath the air enters the pharynx, the trachea, the bronchus,the bionchioles, the alveolus and finally enters th lungs so the trachea moves air into the bronchus.The trachea is made up of ring of cartillage which keep the trachea opened when we inspire and expire
Esophagus is smooth in texture... Trachea is segmented in texture because trachea contains cartilage rings... Due to presence of cartilage rings, it is made sure that the trachea doesn't collapse leading to difficulty in breathing.. Anatomically, trachea is placed ventral to esophagus.
The trachea and lungs are in the respiratory system. The pancreas is part of the endocrine and digestive systems.
