That passageway is lined with muscles and nerves. When food or fluids enter your GI tract, nerves trigger the muscles to initiate a series of wave-like contractions. These muscle contractions automatically move food and fluids forward until they reach their exit at your anus or urethra.
What type of contraction occurs in large intestine?
The large intestine is divided into a colon and rectum, and shows three types of movements: rhythmic ascending (antiperistaltic) waves of contraction originating at the anal end of the large bowel, rhythmic longitudinal contractions in the rectum and colon, and irregular contractions.
What two types of contractions are associated with the small intestine?
Two types of motor activity have been recognized: segmenting contractions and peristaltic contractions. The predominant motor action of the small intestine is the segmenting contraction, which is a localized circumferential contraction, principally of the circular muscle of the intestinal wall.
What is a colonic contraction?
A colon spasm is a spontaneous and sudden contraction of the muscles in your colon. The colon is part of the large intestine. It's responsible for forming, storing, and excreting feces.

This fluid is composed of four primary components: ions, digestive enzymes, mucus, and bile. About half of these fluids are secreted by the salivary glands, pancreas, and liver, which compose the accessory organs and glands of the digestive system. The rest of the fluid is secreted by the GI epithelial cells.
Which system regulates motility and secretion?
The digestive system has a complex system of motility and secretion regulation which is vital for proper function. This task is accomplished via a system of long reflexes from the central nervous system (CNS), short reflexes from the enteric nervous system (ENS) and reflexes from GI peptides working in harmony with each other.
How does the gastrointestinal tract generate motility?
The gastrointestinal tract generates motility using smooth muscle subunits linked by gap junctions. These subunits fire spontaneously in either a tonic or a phasic fashion. Tonic contractions are those contractions that are maintained from several minutes up to hours at a time.

The major processes that occur in the GI tract are: motility, secretion, regulation, digestion and circulation. The proper function and coordination of these processes are vital for maintaining good health by providing for the effective digestion and uptake of nutrients.
