What is trachea and its function?
Your trachea (TRAY-kee-uh) is a long, U-shaped tube that connects your larynx (voice box) to your lungs. The trachea is often called the windpipe. It’s a key part of your respiratory system. When you breathe in, air travels from your nose or mouth through your larynx.
What words best describe the function of the trachea?
Air conduction The primary function of the trachea is to provide air passage to your lungs for respiration, i.e. to inhale air rich in oxygen and exhale carbon dioxide.
What is the structure of trachea?
The trachea is composed of about 20 rings of tough cartilage. The back part of each ring is made of muscle and connective tissue. Moist, smooth tissue called mucosa lines the inside of the trachea. The trachea widens and lengthens slightly with each breath in, returning to its resting size with each breath out.
What does the trachea look like?
The trachea is a hollow, tube-like structure that runs from the larynx, or voice box, to the bronchi — the two passageways that connect the trachea to the lungs. The average length of the trachea is about 11.8 centimeters , and a male’s trachea is typically longer than a female’s.
Why is the trachea C shaped?
The cartilaginous rings are C-shaped to allow the trachea to collapse slightly at the opening so that food can pass down the esophagus.
How is the structure of the trachea adapted to its function?
How is the structure of the trachea adapted to its function? Cartilaginous rings prevent collapse of the trachea.
What is trachea made of?
The trachea is composed of about 20 rings of tough cartilage. The back part of each ring is made of muscle and connective tissue. Moist, smooth tissue called mucosa lines the inside of the trachea.
Why does the trachea not have O-shaped rings?
A normal trachea (windpipe) has many rings made of cartilage (a strong and flexible tissue). These rings are C-shaped and support the trachea but also allow it to move and flex when your child breathes. Complete tracheal rings are a birth defect in these rings that causes them to be O-shaped instead of C-shaped.
How many rings does a trachea have?
The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. The trachea is composed of about 20 rings of tough cartilage.
How many layers does trachea have?
four layers
The trachea has four layers. The inner mucosal layer has a lining of ciliated pseudostratified columnar epithelium with goblet cells.
What shape is the trachea?
Structure and dimensions. The trachea is nearly but not quite cylindrical, flattened posteriorly. In cross-section, it is D-shaped, with incomplete cartilaginous rings anteriorly and laterally, and a straight membranous wall posteriorly.

How wide is the trachea?
The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people.
