What pushes food down our trachea when we guzzle?
Can anyone tell me what pushes food down our trachea when we eat?How does it go down into our stomach and not stay within windpipe even when if a person lies down after eating if that makes sense?
thankfulness
Answers:
Your trachea *is* your windpipe, so you don't want food to go down that (that would be what happens when you choke)... instead, it goes down the esophagus. Basically, when you swallow, a flap of tissue anchored at the root of your tongue (way rear in your throat) moves to cover the trachea, and directs food over and behind it into the esophagus. The esophagus itself has rings of muscle which contract sequentially to push the food towards the stomach (a process call peristalsis). The entrance to the stomach itself is controlled by a sphincter, which is a sort of muscular door that opens to let food in, and contracts to preserve the contents of the stomach in the stomach. When the sphincter doesn't stay closed, and stomach contents get out, the irritation caused by the stomach tart is what causes heartburn.
Edit (to address additional information in question): Usually if the movement of food is impede, it is because of some sort of blockage of the esophagus, for example, due to scarring which narrows and constricts a section of the esophagus (called stricture); the sphincter to the stomach could also become dysfunctional, and not open completely. I cogitate it's pretty hard to actually slow peristalsis in the esophagus due to it anyone a large part skeletal muscle - peristalsis in the intestines (which are mostly smooth muscle) could be slowed by an assortment of drugs (notably opiates), however, so I suppose that the resulting backup might eventually slow stomach emptying and lead to backup in the esophagus as capably. Food trapped in there won't really become "toxins," but it could certainly start to oxidization (it's like leaving food in any heat up, wet location) or become a site for infection, so it would be harmful in that course.
food does not go down the trachea, which is the wind pipe. it goes down the esophagus. near is a flap that closes off the trachea as we swallow. food is pushed down by peristaltic movement of the esophagus. I hope this helps you.
