THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.

Detailed explanation-2: -The first bronchi branch from trachea, and they are the right and left main bronchi. These bronchi are the widest and they enter the lung. After entering the lungs, the bronchi continue to branch further into the secondary bronchi, known as lobar bronchi, which then branch into tertiary (segmental) bronchi.

Detailed explanation-3: -The trachea, also called the windpipe, branches into a bronchus in each lung. The bronchi then branch out again and become smaller and smaller passageways until they end in tiny air sacs called alveoli.
