So you can actually breathe in and out
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.
keeps the trachea open when the head is bent or turned
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.

A large ring of cartilage typically refers to the tracheal cartilage rings that provide support and structure to the trachea (windpipe) in the respiratory system. These rings help to keep the trachea open and prevent it from collapsing during breathing.
Food would get into your trachea (air pipe).
All respiratory systems are open as the function of a respiratory system is to exchange gases with inside of the body and the external world. The term 'open' or 'closed' refers to the vascular system.
The trachea is a passage that enables air to travel between the Oral and Nasal cavities into the Bronchus, in order to reach the lungs. The trachea is supported by cartilage that keeps it open, however the rings are not complete (except for the Cricoid Cartilage) which allows for flexibility.
The structure of the trachea consists of cilia and mucus-producing cells that help trap and remove particles and microorganisms from the air we breathe, protecting the lungs. This also helps to prevent foreign substances from entering the digestive system via inhalation. Therefore, the structure of the trachea plays a vital role in maintaining respiratory health while also supporting the separation of the respiratory and digestive systems.
1) Nasal passage- This is your nose. Air enters here and is moistened, warmed, and cleaned. 2) Trachea- Your windpipe. It is held open by rings made of cartilage. Air passes through here. 3) Bronchi- Two tubes that branch from your Trachea. They each lead to a lung. 4) Bronchioles- Smaller branches coming from the Bronchi. 5) Lungs- An organ containing alveoli. 6) Alveoli- The smallest working part of the respiratory system, and the respiratory surface. They are moist and one-cell thick and are surrounded by capillaries for call exchange. That's about it :)
