If you eat food while hanging upside down, do you think it will still go through the alimentary canal? Give Reasons...
andrew11 [14]

Answer:

Our alimentary canal undergo a process or a movement called peristalsis, in which the walls continuously move to pass the food downwards. So if you eat hanging upside down, the food would surely move.

Explanation:

  • Peristalsis is a series of wavelike muscle contractions that moves food to different processing stations in the digestive tract and the process begins in the oesophagus when a bolus of food is swallowed.
  • The muscles of the oesophagus are strong enough to propel food and liquids into the stomach even when hanging upside down although there is a risk of choking
  • It is advised that maintaining a correct body positioning during eating is very important for digestion to happen properly and avoid blockage of the airways by food and fluid.
  • Leaning your body upright slightly and rounding your shoulders a bit so that your chin is tucked-up is a way of exercising safe chewing and swallowing.
