Q1) There are occasions when we tend to choke on our food and are unable to breathe. Human beings have separate food and wind pipes. So, what could be the reason for the choking?
Answers
Answer:
Choking is caused when a piece of food or other object gets stuck in the upper airway. In the back of the mouth are two openings. One is the esophagus, which leads to the stomach; food goes down this pathway. The other is the trachea, which is the opening air must pass through to get to the lungs.Most choking episodes are simply due to a mistake made during eating — eating too quickly, laughing while eating, taking too big of a bite. Such mistakes can send chunks of food hurtling down the throat and into the lungs.
