Diagram of Trachea

A diagram of trachea is useful for understanding its anatomy and the functioning of the respiration process. The trachea functions in the respiratory system as a conduit for air, allowing oxygen to enter the lungs while allowing the expulsion of carbon dioxide during exhalation. The trachea diagram class 10 is important to understand the process of respiration.

The labeled diagram of trachea is given below:

Diagram of Trachea

What is Trachea?

The trachea diagram shows it as a flexible, large hollow tube that brings air from the nasal passages, throat, and larynx to the two large airways that branch off into each lung. An important trachea function is warming and moisturizing of the air, as well as catching debris and microbes before they can enter the lungs when a person inhales. When the lungs expel the air, it travels back up the trachea and out through the mouth or nose.

Trachea Location

The trachea, often called the windpipe, is located in the neck and upper chest region, extending from the larynx to the bronchi. Positioned anterior to the esophagus, it runs vertically down the midline of the body, providing a conduit for air to pass into the lungs during breathing.

Trachea Anatomy

The trachea has an average length of 11.8 cm and is typically longer in men than in women. In an adult, the trachea length is typically 4 to 5 inches and 1 inch wide. As visible in the diagram of trachea, the cricoid cartilage is a ring of cartilage that connects it to the larynx. The trachea descends into the chest and is surrounded by 16 to 22 U-shaped cartilage rings that act as scaffolding, allowing air to flow through.

The trachea’s rear wall is softer because it is made up of connective tissue and smooth muscle, allowing the esophagus to expand as a person eats, and it can flex and extend to make the windpipe larger or smaller. The trachea ends at a cartilage ridge that separates and connects the bronchi (carina). Due to its closeness with oesophagus, a small piece of cartilage in the larynx spontaneously covers the aperture of the trachea, preventing food or drink from entering it when the individual is eating.

Membranes of Trachea

The trachea diagram shows the interior is lined with a mucous membrane composed of mucus-secreting goblet cells that help keep bacteria and debris from entering the lungs. In addition, small hair-like projections called cilia inside the trachea aid in the removal of mucus containing debris or pathogens.

Submucosal glands reside within these membranes and act as partners to goblet cells by secreting water molecules and the gel-like component of mucus (mucin) onto the tracheal lining. The trachea also contains a network of blood and lymphatic arteries. Blood arteries provide oxygen and nourishment to the tissues while also regulating heat exchange within the airway. The lymphatic veins assist removes infectious germs off the surface of the trachea wall, allowing the immune system to deal with them.

Conclusion – Diagram of Trachea

The diagram of trachea shows a tube that transports air to and from the lungs. It also helps to keep bacteria, debris, and cold or hot air out of the lungs. Their complex structure can be studied with the help of labeled diagram of trachea. Its inner lining made up of mucous membrane which consist of goblet cells, cilia and epithelial cells. If a person is having difficulty breathing, it is probable that a health problem is affecting their trachea, and they should seek medical assistance right once.
