The name of the structure at the top of the esophagus is the "epiglottis". This structure is very important in protecting the vocal cords, trachea, and the lungs. It does this by covering the opening to the vocal cords and making an airtight seal. It also holds air in our lungs so we can form a cough, and produce extra pressure in our lungs, called "peep" (positive end expiratory pressure). So, it is actually a very important organ.
This flap is called the epiglottis. You close it when you swallow so what you eat or drink doesn't go down the trachea ("wrong pipe").
Epiglottis
epiglotis
The esophagus and trachea open into the throat and mouth.
The organ that branches off in front of the esophagus is the pharynx.
They meet at the epiglottis. The epiglottis is the flap of muscle that closes over your windpipe when you swallow food.
The epiglottis is very short, and fits right over the esophagus. It is a small flap of flexible cartilage tissue that protects the windpipe.
The valve between the esophagus and the stomach is called the lower esophageal sphincter.
To keep food from going into the lungs.

Down, the flap that I think you're referring to is the epiglottis which closes of your respiratory airway when you swallow so food is directed down the esophagus instead.
Okay if I get what you are saying, there is a little flap called the epiglottis that switches between covering the esophagus and trachia. When you are eating food this flap covers the trachia so you don't get food in your lungs (that would be very bad) and when you're just breathing normally the epiglottis covers your esophagus so you can actually breath. I you think you have a problem with your epiglottis then go to the doctor immediately. Hoped this answered your question. If not well you just learned something new today! ^_^
The organ that branches off in front of the esophagus is the pharynx.
It is also called an attached flap.
They meet at the epiglottis. The epiglottis is the flap of muscle that closes over your windpipe when you swallow food.
The anagram is "epiglottis" - a flap in the throat that directs air to the trachea (to lungs), and food to the esophagus (to stomach).
It is called the Epiglottis. If you talk while eating, your epiglottis and your esophagus are open, so instead of going down the esophagus, it goes down the epiglottis. Have you ever heard someone say 'It went down the wrong tube' when you choke? This is what they mean.
The flap of skin at the elbow is called a wenus.
