Hyaline cartilage, which also covers the ends of bones at the joints, which reduces friction during movement.
Many mammals have cartilage rings in their tracheas, which may also extend down the mainstem bronchi. These rings are in place to physically keep the major airways propped open so that air can flow easily.
Cartilage is a tough, flexible connective tissue that is present in the walls of the respiratory system, such as the trachea and bronchi. It provides structural support and helps to keep the airways open during breathing.
The walls of trachea contain c-shaped rings or cartilagenous rings.These soft bones provide rigidity to the trachea , that is why the walls of trachea doesn't collapse when there is less air.
The trachea splits into the left and right bronchi in the thoracic cavity(the chest). From there the bronchi continue to branch out and keep getting smaller. Kind of like the branches on a tree. At the end of the those branches (bronchioles) are the alveoli( tiny grape like structures). In the alveoli is where the exchange of oxygen and carbon dioxide occur.
The trachea (windpipe) is the tube in the neck with rings of cartilage. It connects the larynx (voice box) to the bronchi, allowing air to pass in and out of the lungs. The rings of cartilage help to keep the trachea open and prevent it from collapsing.

Cartilage in the respiratory system (usually found in the trachea and some small amounts in the bronchi), is to act as a way to keep the passageways open.
The trachea contains cartilage rings and mucous glands. The bronchioles contain no cartilage and no mucous glands. Bronchioles contain Clara cells (that the trachea does not). Respiratory bronchioles contain alveoli, which are very thin-walled blind ending sacs where gas exchange occurs - these are not present in the trachea.
Tracheal cartilage rings provide support and prevent collapse of the trachea during respiration. They are C-shaped structures made of hyaline cartilage that keep the trachea open to maintain a patent airway for the passage of air in and out of the lungs.
two like structures that lead to the lungs and branch off into the broncoe. (trachea) The two main bronchi are formed when the trachea (or windpipe) divides. The right bronchus is more vertical than the left. It is also wider and shorter. It is approximately 2.5cm in length and after entering the right lung it divides into three branches (one going to each of the three lobes of the right lung). Each branch then divides into many smaller branches. As the bronchi get smaller, they are called bronchioles. Bronchioles become terminal bronchioles, then respiratory bronchioles, alveolar ducts.. and finally alveoli. The left bronchus is about 5cm in length and is narrower than the right. After entering the left lung, it divides into two branches (one for each of the two lobes of the left lung). Each branch then divides into smaller bronchi in the same way as the bronchi in the right lung, ending in the alveoli. The bronchi are lined with ciliated columnar epithelium. This contains cilia which are hair like extensions that propel materials along the airways. This helps to keep the airways clear.
The rings are to keep the trachea open but they are not complete posteriorly because the esophagus runs there. The soft space allows the esophagus to fully expand when food is passed down to the stomach.
The trachea, or windpipe, is essential for respiration as it serves as the main airway that connects the larynx to the lungs. It allows for the passage of air in and out of the lungs, facilitating gas exchange. The trachea is also lined with cilia and mucus that trap and expel foreign particles, helping to keep the respiratory system clear and functioning properly. Without a healthy trachea, effective breathing and oxygen delivery to the body would be compromised.
