Hey! When food enters the lungs instead of the esophagus, it affects breathing and can cause choking and other problems. The structures inside the mouth and neck each have a distinct role in breathing, speaking and swallowing. The swallowing mechanism is a complex process that, when it works properly, moves food to the esophagus for transport to the stomach. Dozens of muscles and nerves work to move food in the right direction. A piece of cartilage called the epiglottis plays a key role in ensuring that food does not enter the windpipe or the lungs. Hope this helps!

HURRYY!!<br><br> Why have American's portion sizes become larger in the last decade?

Viefleur [7K]

Answer:

American's portion sizes have become larger in the last decade due to the expanding of food industries and marketing campaigns that tell us to eat more.

Explanation:

The growth of food industries in the last decades to obtain more money in combination with the media influence has led us to eat more, thus why the size of our portions has increased their size.

Another theory states that people always want to eat more, and the industry has only fulfilled this demand, but it is not clear why, in the past, this did not happen.
