Chen Cang took the scalpel and began the procedure!
The human body is the most precise and complex instrument, and the neck is a bridge within the body.
There are many things there, but those most closely related to our daily lives are the trachea and esophagus.
Interestingly, both the trachea and esophagus are directly connected to the pharynx above. During breathing, the airway to the trachea opens while swallowing, the food passage opens, and the airway closes to prevent errors.
Therefore, when we perform nasogastric intubation or gastroscopy in clinical practice, we often need the patient to cooperate by swallowing to prevent the tube from mistakenly entering the trachea, causing choking and endangering life. The common practice of not talking or laughing loudly while eating is also to prevent food from mistakenly entering the trachea and causing suffocation.
