Your trachea, or windpipe, allows air to come into your body and through your lungs. If food gets trapped inside your trachea, you cannot breathe.

Epiglottis's job is to prevent food entering the trachea and forces the food into the oesphagus.
the tracheas job is to help push objects in the throat out the way so that air can get through
To maintain and protect the air way, by its cartilegenous ring,and traping (stiking )of tiny dust particle on the mucosal surface,and remove it by coughing up, Dr.I.A. Sheikh (MD rus) ssma 2005
The singular for trachea is "trachea". The plural is "tracheae".
sometimes, it's known as "going down the wrong pipe". It does a good job usually.
If you mean choking/suffocation so the reason is simple. In order for the food we eat to go to the trachea instead to the esophagus, there is a cartilage tissue called the epiglottis. Its job is to block the trachea while swallowing. That is the reason we don't breath in the same time we actually swallow. When the epiglottis fails doing its job and the trachea remains open while swallowing, substances can enter the trachea (and they are definitely not welcomed there) and block it which eventually leads to the coughing you mentioned. It can happens basically if we eat very fast, or talk while eating.
No trachea is not the lung.
