Fiber is the nutrient that helps move food through the digestive tract. It provides bulk, which activates the stretch receptors in the muscles of the digestive tract, stimulating them to activity.
PeristalsisPeristalsis
Food moves through the digestive tract.
Water is absorbed from the digestive tract through a process called osmosis, where water moves from an area of lower concentration to an area of higher concentration. This occurs mainly in the small intestine, where nutrients and water are absorbed into the bloodstream through the walls of the intestines.
The food is passed through the digestive tract when the worm moves. The movement causes the muscles to contract and move the food through the system.
Food moves through the digestive tract primarily by a process called peristalsis, which involves rhythmic contractions of the smooth muscles lining the digestive organs. These contractions push the food along the esophagus, stomach, and intestines. Additionally, segmentation occurs in the intestines, mixing food with digestive juices to enhance absorption. Together, these movements ensure the efficient breakdown and absorption of nutrients.
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
Propulsion is the movement of food down the esophagus and peristalsis is the contractions in the stomach walls that moves food through the digestive tract.

Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed from the digestive tract directly into the blood.
Peristalsis, a series of muscle contractions in the intestines and stomach that help to push the food through your digestive tract.
Peristalsis, a rhythmic contraction and relaxation of muscles in the digestive system, helps move food downward through a vascular plant. This motion aids in pushing the food along the digestive tract and aids in the breakdown and absorption of nutrients.
