Peristalsis (rhythmic muscular squeezing) of the esophagus.
It helps move food through the digestive track by creating waves in the walls of the "tube" which pushes the food down. Not sure where else this applies in the body.
A fridge works by absorbing the thermal energy (heat) out of the things you put in it and a compressor pushes the thermal energy from the food through a tube into the air outside of it.
The person's feet push backward on the sidewalk; the sidewalk pushes forward on the person.
compressive force
The reaction is the wall pushing back on you.
You start digestion in your stomack
stomack
Your stomack growls because the inside of your stomack ist wavey and the bumps rub together when its empty because they do that to grind up food so when they rub together it makes a growling sound
sphincter
Several factors contribute to men developing a larger stomach after the age of 40, including a decrease in metabolism, reduced muscle mass, hormonal changes, poor diet, and lack of physical activity. These changes can lead to an accumulation of excess fat, particularly around the abdomen, resulting in a larger stomach. Adopting a healthier lifestyle, including regular exercise and a balanced diet, can help prevent or reduce this stomach size increase.
"Chyme" is the souplike food mass that leaves the stomach and passes into the duodenum (the first part of the small intestine).
they pick up the food with their legs and pop it in their mouths
The organs that your food passes through pushes it along. E.g: The esophagus (aka: The gullet) squeezes and pushes the food down. That's why you can eat upside down without the food coming back up!
stomack
the acids in your stomack burn the food in to a solid and if you drink something like water, juice,etc it messes up the acids and it dont work right :)
