MICROANATOMY

Detailed explanation-1: -From the windpipe, air moves into the lungs through tubes called bronchi. The bronchi lead to smaller tubes called bronchioles, which look like the branches of a tree.

Detailed explanation-2: -When you breathe in (inhale), air containing oxygen enters your windpipe, passes through the bronchi and eventually reaches the air sacs. These air sacs, called alveoli, are responsible for gas exchange. They look a bit like grapes at the end of the bronchial branches.

Detailed explanation-3: -When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.
