Question

The pathway through which air passes from the nose to the trachea and lungs crosses the pathway through which food and water pass from the mouth to the esophagus and stomach. as a result humans often suffer from choking. how can we explain this particular human vulnerability

Answer 1

When an individual experience choking, it means that there is an obstruction of the air flow and it prevents partial or even complete breathing.  The obstruction of the airways in an act of choking is occurring at the level of the trachea or pharynx, and in terms of food, it is mostly in the pharynx.
