right because the left has recess that accommodates the heart
what is longer considering the primary bronchi
The right primary bronchus is larger in diameter.
The right bronchi is larger because the left has to make room for the heart.
The left bronchi.
Bronchi is branched in primary and secondary. bronchi is branch of bronchus.

trachea- primary bronchi- secondary bronchi- tertiary bronchi- bronchiole- alveoli
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.)
The largest diameter airways are the mainstem bronchi. Smaller-diameter airways are the bronchioles.
The trachea branches into the left and right main bronchi, which further divide into smaller bronchi within the lungs. These smaller bronchi continue to branch into bronchioles, which eventually lead to alveoli where gas exchange occurs.
Bronchi (primary)
Yes. You have primary, secondary, tertiary and about seventeen such generations of bronchi. They are part of the lungs.
