be careful where you clique
There’s some pretty complex arrangements your trachea makes every time you swallow. Think and it shall be done.
Notice the outcropping in the distal pharynx as the fluid runs down. That’s not normal… unless you’re part bird.
The esophagus has some weak points. The top third is all skeletal muscle- that means it’s under your voluntary control. By the time things slip down towards your stomach, it’s all autopilot.
Every once in a few thousands of people, the cricopharyngeus muscle can spazz out and herniate…. leaving you with a little pocket- a chance for halitosis and the opportunity to regurgitate breakfast. Barium Sulfate and some xrays can help with the diagnosis. Barium Sulfate is also used to make green fireworks go boom.
