Why does the cartilage form incomplete C rings in the trachea?

My big question is its more regular in trachea than bronci, but why is there C rings in trachea not so much in bronci?

you need the rings of cartilage as when you breathe in the pressure falls, the rings prevent the trachea from collapsing, in other words they're there for support during ventilation.

Tanx. Why are the incomplete rings more regular in trachea and not the bronchi?

If I remember correctly from last year, the C rings in the trachea is so you can turn your neck.

As the roatation is not needed in the bronchi there is no need for the C shape

In your bronchi you'd find that they have a muscular wall, this enables to to contract and relax meaning they can control the amount of air into and out of the lungs.
