It was asked on the online platform Quora that when astronauts drink water or eat food in the micro gravity of space, how does it enter their stomach? A user named Animesh Kumar Sinha answered this. you should also know.

There is a system for our food and drink. Whenever we eat Khojan, it reaches our throat. Then from there there is gradual contraction and expansion of the muscles of the esophagus, through which the food reaches our stomach. Gravity has no role in this. The importance of gravity is zero in this entire process of food reaching the body. That is why when astronauts drink water or eat food in micro gravity, the food goes into their stomach just like they eat food on Earth.

Esophagus connects the throat to the stomach
According to experts, esophagus is a tube that connects our throat to the stomach. When the teeth break the food into small pieces, it then mixes with the saliva and forms small pills. When this pill reaches the esophagus, it gradually contracts. This contraction and expansion is called peristalsis.

Two types of muscles in the esophagus
Talking about the internal structure, there are two types of muscles in the esophagus. One circular and the other long. It also has a valve, which is of very high pressure. It prevents food from coming back from the stomach. You can also understand it in this way that if you have eaten food and as long as it is in your throat, you cannot go into the reverse headstand position. But if it goes down the throat then you can easily do Shirshasana. During this period food will not come out of your stomach.
