Why is the trachea reinforced with cartilaginous rings?

Answer 1

ANSWER:To support the trachea. If the rings were not there or if there were not a positive air pressure to keep this area open, it would close on its own because of the surrounding force of the body would close it. If they weren't there you would gurgle upon inhalation and exhalation.

The 'c' shaped cartilage rings are present in the trachea to prevent it from collapsing and they keep the trachea open for air to come in and out. In humans there are about 15 - 20 incomplete C-shaped cartilaginous rings which reinforces the anterior and lateral sides of the trachea to protect and maintain the airway open. (The cartilaginous rings are incomplete because this allows the trachea to collapse slightly to allow food to pass down the esophagus
to give support
The rings of cartilage strengthen the trachea so that it does not collapse, but remains open so that air can get through it.
If It didn't it would collapse in on itself and you would be unable to breathe.
we breath every time so trachea keep open all the time .cartilage rings give support to trachea to open all the time.
The cartilage rings in the trachea keep it from collapsing upon itself with the negative pressure inside of it during inhalation.
The Trachea (also known as the wind pipe) has cartilage rings on it. This prevents the pipe collapsing on itself. If the trachea did collapse, it would disallow us from breathing. Also the trachea might collapse and damage the esophagus (also known as the food pipe) which is behind it.

I'm in Year 8 (or Grade 8 in the (U.S)) and i know that. ;P
It stops it from collapsing when bending the neck, and protects it from tears and other damage.
The trachea (windpipe) has cartilage in it so that it won't collapse when you move your head.

Answer 2

When you inhale, the expanding lungs create a lower air pressure in order to suck in more air, but that lower pressure would also cause the trachea to collapse, if it were not held open by some rigid structure, which is provided by the rings of cartilage.

Answer 3

When breathing, the air pressure in your trachea can be less than the ambient air pressure (as the lungs expand, to draw in air, they create a slightly lower air pressure). This would cause the trachea to collapse if it were not supported by its cartilaginous rings. And even the muscular effort of swallowing would be a danger to the trachea if it were not supported in this way. The trachea has to be kept open, so that you can continue to breathe.

Answer 4

To keep them from collapsing due to negative pressure on an exhale.

Answer 5

The trachea contains rings of cartilage to act as a shock absorber and to help support the neck so air can go through freely. I LOVE TO HAVE SEX!

Answer 6

because trachea need support and cartilage rings give it support

Answer 7

yes
