Food is supposed to enter the oesophagus for it to reach the stomach.
If you mean what prevents food from entering the trachea/windpipe, then the epiglottis is a leaf-shaped piece of cartilage that closes over the trachea to prevent food/drink from entering it during swallowing.

Why is the esophagus lined with stratified squamous epithelium as opposed to simple columnar epithelium?
stratified squamous has many layers of cells; more mature cells at the top and younger cells near the base. it is seen in lumen's and organs that have high abrasion rates. the esophagus moves food bolus from the mouth to the stomach, the 'abrasion' caused by the food passing down through the stomach causes rubbing of the lining which removes cells. thus the esophagus needs many layers of cells so that it can withstand this abrasion and make more cells to replace those lost. note though, that the esopagus at the bottom 3rd (usually past the diaphragm layer) is made of tall columnar cells to deal with the refluxing stomach acid. Barretts esophagus is a premalignant condition where this epithelia spreads further up the esophagus and causes much pain to the person!!
Does Mitosis occur in the lining of the stomach?
No, mitosis does not take place in the lining of the stomach. It actually takes place in the inside of the abdomen, which people usually mistake for the stomach.
How is syndactyly prevented?
Syndactyly can be corrected surgically, usually with the addition of a skin graft from the groin
What makes the burping noise when you burp?
The burping noise is caused by air rushing past the loose tissue of the upper esophagus, the tube that leads from the throat to the stomach. It is usually closed when you are breathing, and opens when you swallow. So when air from your stomach rushes up real fast, it vibrates the upper part of the tube. The same thing happens to a whoopie cushion when the air is squeezed out of it; the loose end makes a farting sound. You could think of burping as being the opposite of farting, because the same principles of creating sound are at work for both. you can also make one on purpose simply by inhailing with esophagus closed but open 1%
What connects the pharynx to stomach?

Is cardioesophageal and gastroesophageal same thing?
No. Cardio- = heart Gastro- = stomach Esophageal = of or pertaining to the esophagus Edit- Yes. The Lower Esophageal Sphincter (LES) is also referred to as the Cardioesophageal Sphincter and the Gastroesophageal Sphincter. This sphincter separates the esophagus from the stomach and is usually in a closed position. When there is weakness in the sphincter gastric juices may go up into the esophagus resulting in heartburn.
Can a person eat a bee if alive even if alive?
It would be risky to swallow a living bee, since it might sting your esophagus on the way down. However, it would not live long. Once it enters the stomach, the stomach acids would kill it. Stings to the inside of your esophagus and stomach lining are very painful and usually require medical treatment.
What keeps food or fluid from going back up the esophagus to the lungs?
If you are vomiting it does. But usually food doesn't go back into the esophagus because it tends to go down hill, going back into the esophagus is going against gravity. ---------- Also, the lower esophageal sphincter normally prevents stomach contents from flowing backwards. Sphincters are rings of muscle that open and close to control the flow in various places in the body.
Heartburn has nothing to do with the heart but actually involves?
Heartburn involves the stomach and usually the esophagus. When acid refluxes into the lower esophagus it creates a nasty burning sensation since the esophagus does not have the same protective coating as the inside of a healthy stomach. The pain can be reminiscent of the pain of a heart attack - leading some people to mistake a heart attack for bad heartburn and others to mistake bad heartburn for a heart attack.
What is pH for acid reflux victims?
It is usually not too high of acidity that causes acid reflux. Acid reflux is a product of a faulty cardiac sphincter, which allows the highly acidic chyme to flow back into the esophagus. Your esophagus is not protected from the acid like your stomach is with the stomach lining of mucus. The pH range of stomach acid is about 1.5-2, which is strong enough to dissolve iron nails.
What organ is damaged by heartburn?
The esophagus, which is the tube that carries food and drink down your throat and into your stomach. When heartburn occurs, it is usually because there is acid activity at the base of the esophagus, which causes the burning feeling. It can also be because of a gas buildup or bubble, or even by previous irritations in the esophagus. Mostly though it is due to stomach acid bubbling up into the esophagus and causing irritation, which can become inflamed and irritated and prolong the burning. In severe cases this acid irritation has been known to turn into ulcers, and even cancer. At the first sign of heart burn take an antacid or drink something to coat your esophagus, as it takes the hardest beating.
What causes laryngopharyndeal reflux?
At both ends of your esophagus there is a ring of muscle. Usually, the muscles keep your stomach's contents where they belong. With laryngopharyngeal reflux, the muscles don't work right and stomach acids backs up into your throat.
What is esophageal cancer.?
Esophageal cancer is a type of cancer that attacks the esophagus. The esophagus is the muscular tube connecting the throat to the stomach. It is about 10 to 13 inches long. The food you eat needs to pass through the esophagus in order to reach the stomach for further digestion to take place. The esophagus is made up of several layers and cancerous cells usually begin to multiply in the inner layer and grow out to the outer layers. There are two types of esophageal cancer: adenocarcinoma and squamous cell carcinoma.
