What is the difference between trachea and bronchi?

Answer 1

Bronchi (plural of bronchus) are tubes that branch off from the trachea into each lung. Bronchioles are smaller tubes that branch off from each bronchus. Also there are only two bronchi compared with the hundreds of bronchioles

Answer 2

The trachea, also known as the "windpipe," is the largest tube of the respiratory system. In the adult human it is approximately 5 inches long, and an inch in diameter. It technically begins at the inferior edge of the larynx (aka "voice-box") and continues down toward the lungs. At the inferior end of the trachea it bifurcates, or divides, into two slightly smaller tubes known as bronchi. The primary bronchi each divide into "secondary bronchi." On the right side, the primary bronchus (the term for a single bronchi), divides into a superior and an intermediate bronchus (secondary bronchi) before it enters into the right lung. On the left side, the primary bronchus enters the left lung, then divides into a superior and and inferior bronchus (secondary bronchi.)

Answer 3

This had been my favorite question! The answer by students has almost always been. Primary bronchus, then secondary bronchus, the tertiary bronchus and then the bronchiole. From trachea, you get ten primary bronchi in both the lungs. Then you have twenty secondary bronchi. Then forty tertiary bronchi. Like wise you have almost seventeen divisions. The last one is called as bronchiole. Then you get the alveoli. Which divide six times, in turn. You please take the calculator and calculate the number. That is why the surface area of your lung is about 1000 or 1100 square feet or 100 square meters. You do not have those cartilage rings, present in bronchioles.
