Why is it possible for spacemen to pass food down their esophagus in the absence of gravity?

The food is transported down the esophagus by a process called 'peristalsis' - NOT gravity. The food is 'pushed' by the contraction of cartilage rings around the digestive tract. This is why you can (for example) swallow a drink sipped through a straw, while standing on your head.

How do spacemen eat?
It will be tricky as the food will float due to lack of gravity, it must be put in the mouth fast.
Why do spacemen need to wear pressurized suits?
They have to where prussurized siuts because the gravity passed the atmosphere has gotten much more dense .
What would happen if earth didn't have gravity?
If the earth had no gravity it follows that gravity would be absent from any mass. In the absence of gravity life would not exist.
Are gravity and no gravity alike?
They are similar, in that one is the absence of the other. However, they are not opposites, so they could not be considered 'alike'.
Do astronauts have weights in their space suits?
None, because of the absence of gravity
Is zero gravity possible?
It's possible. There is a zero gravity area in the sea.
How is food moved along the asophagus?
the asophagus by, the muscles in the (Gullet) by contractions in the gullet. i think ?
What do spacemen do to overcome the reduced amount of gravity that they experience on the moon?
-- There have been no 'spacemen' on the moon for 40 years now, and there isno planning going on right now to send any more.-- Increased gravity would need to be 'overcome'. Decreased gravity doesn't.-- After the total weightlessness (zero-gravity) during the 3-day trip just to reachthe moon, the return of gravity, even if it's only 16% of what it was on Earth, is awelcome relief.-- When the spaceman leaves the landing module and walks on the surface, themassive pressure suit, helmet, boots, and air conditioner he has to wear outsidemake him feel more normal on the moon than he would without all of that.-- Astronauts train for months to learn to function in environments with differentvalues of gravity.
What would happen to a car if there was no gravity or air?
If no gravity or air existed the car would never have been invented. It will not work in the absence of either.
What tube conects to the mouth and stomach?
The esophagus (also spelled Oesophagus) is the tube that connects the mouth and the stomach. It works through continuous wavelike muscle contractions known as peristalsis, along with downward gravity, to move food and liquids from the mouth and throat into the stomach.
Is it possible for an object not to have a center of gravity?
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
Does the esophagus breakdown food?
The espohagus doesn't breakdown food, it just carries it from the mouth to the stomach. Not by gravity, but by musclar energy.
