Why is it important that the human trachea is reinforced with cartilaginous rings

It is important that he human trachea is reinforced with cartilaginous rings to keep the passage open as pressure keeps fluctuating during the process of breathing.

Explanation:

The trachea is reinforced with cartilaginous rings as it doesn't allow the trachea to collapse in our day to day lifestyle. It also keeps the air way passage open in spite of the continuous pressure changes during breathing.

The rings are not complete posteriorly  to provide another advantage, that is it allows the esophagus to expand anteriorly ( inside the body) when we swallow food.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
