is it harder to shallow and digest food in space
Answers
Answer:
The Correct Answer is mentioned below
Explanation:
Peristalsis is a biological mechanism that is a part of human body. There are smooth muscles along our digestive system that reflexively contract in a wavelike rhythm, even though we have no awareness of it. These contractions function like our hands on the exterior of a toothpaste tube, forcing the toothpaste's contents down the tube further. We don't require gravity to eat or drink because of peristalsis. Even on Earth, this is significant because our digestive system isn't always vertical, and many of our animal counterparts' digestive systems are horizontal.
Because not all species have peristaltic capacity, some struggle in zero-G environments. When the Russians tried to produce quail aboard the space station Mir, they discovered this the hard way.
When you watch most birds eat or drink, you'll notice that they tip their beaks upwards to swallow their food or drink, allowing gravity to carry it down their digestive tract. Pigeons are an exception; they can eat with their heads down.
The stomach acids do their function in zero-G just like they do in one-G once the meal is in the stomach. However, there is one snag. On Earth, the stomach's gas and liquids separate, with the gas rising above the liquid. So when you burp, all you're doing is releasing gas. Because there is no way to keep gas and liquids apart in space, burping can result in liquids being evacuated as well. It's similar to acid.
