Peristalsis or muscles in your esophagus contract in a wave pushing the water to your stomach
Peristalsis and esophgeal musclulature.
Yes
The same way that a person can be upside-down on Earth and still swallow water. The ability to swallow has nothing to do with gravity; it has to do with the muscles in the esophagus which move food and water from the throat to the stomach.
If I remember correctly, Peristalsis is what allows this to happen. Hope that helps :)
yes you have a esophagus for when you eat food that has muscles that pushes food down to your stomach, that's why you can swallow even if your upside down and you have a trachea for air.
Drink out of a water bottle. Trying to use a glass may result in spilling some water, which will enter your nose!
You turn Upside down.
While most animals have a difficult time swallowing their food when they are held upside down, there is one animal that cannot swallow when held in this manner. This animal is a chicken.
Leaves turn upside down when it rains to prevent excess water from collecting on their surface. This helps the plant avoid waterlogging and allows for better gas exchange and photosynthesis.
No, whales do not sleep upside down. They typically sleep by resting one half of their brain at a time while remaining upright in the water. This allows them to continue breathing and be aware of their surroundings.
Humans don't need gravity to swallow, although, interestingly, birds (i.e. canaries) do.
Yes. It's slightly more difficult because you're working against gravity, though. The oesophagus is a tube-like organ, and the act of swallowing squeezes the food through the tube to down to the stomach, or sideways, or up as the case may be.
