When we think of body parts, we often think of the ones that we see every day like our arms, legs, and face. But did you know that there's a body part that starts with the letter E? In this article, we'll dive into what this body part is, what it does, and some interesting facts you might not have known about it.

What is the Body Part That Starts With E?

The body part that starts with E is none other than the epiglottis. The epiglottis is a flap of tissue located at the base of the tongue that acts as a gateway to the trachea (windpipe) and esophagus (food pipe). Its main function is to prevent food and liquid from entering the trachea and lungs when we swallow.

When we swallow, the epiglottis closes off the trachea and directs food and liquid down the esophagus and into the stomach. This process happens automatically and is essential for preventing choking and aspiration, which is when food or liquid enters the lungs and can cause respiratory distress.

Interesting Facts About the Epiglottis

While the epiglottis may seem like a small and unimportant body part, it actually has some interesting facts and functions that you might not have known about:

1. The Epiglottis is Made of Cartilage

The epiglottis is made up of a tough, flexible cartilage that allows it to move and bend when we swallow. This cartilage is also found in other parts of the body, such as the ears and nose.

2. The Epiglottis is Controlled by the Brainstem

The brainstem is the part of the brain that controls many automatic functions of the body, including breathing and swallowing. When we swallow, signals from the brainstem tell the epiglottis to close off the trachea and direct food and liquid down the esophagus.

3. The Epiglottis Can be Damaged by Acid Reflux

Acid reflux is a condition in which stomach acid flows back up into the esophagus, causing a burning sensation and sometimes damage to the lining of the esophagus. In severe cases of acid reflux, the acid can also damage the epiglottis, making it less effective at preventing choking and aspiration.

Conclusion

The epiglottis may not be the most well-known body part, but it plays a crucial role in our ability to swallow and breathe safely. Without the epiglottis, we would be at risk of choking and aspiration every time we ate or drank. So next time you swallow, take a moment to appreciate this important little flap of tissue that keeps us safe and healthy.
