Hai steemians .....
Good morning everyone, good luck always .....
This time I will share knowledge for steemit's friends ......
Air entering through the nose will be passed to the windpipe (trachea).
Inside the chest, the trunk is split in two. The shape is like a pipe - a small pipe called a throat branch (bronchi).
This bronchus is connected to the lungs

Hopefully useful for all of us, and thank you for your visit in my blog.
