they are a band of longitudinal layers has been reduced to the muscular bands of the taeniae coli. It helps for mixing and propulsive contractions
The walls of the large intestine contain smooth muscle tissue. This type of muscle is involuntary and helps facilitate the movement of contents through the digestive tract via peristalsis. Smooth muscle layers in the large intestine include an inner circular layer and an outer longitudinal layer, which work together to regulate intestinal motility.
Teniae coli Teniae coli Teniae coli
The muscle associated with the intestine is primarily the smooth muscle, which is responsible for peristalsis—the rhythmic contraction that moves food through the digestive tract. Additionally, the circular and longitudinal layers of smooth muscle in the intestinal walls facilitate digestion and absorption. In the context of the large intestine, the taeniae coli, a band of smooth muscle, helps in the formation of haustra, or pouches, in the colon.
Ileocecal valve
Yup definately :)
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine.
small because it has more villi
Haustration is the mixing of feces to expose it to the surface of intestine to absorb water. they are sac like structures foldings in large intestine. At each of these constrictions, about 2.5 centimeters of the circular muscle contracts, sometimes constricting the lumen of the colon almost to occlusion. At the same time, the longitudinal muscle of the colon, which is aggregated into three longitudinal strips called the teniae coli, contracts. These combined contractions of the circular and longitudinal strips of muscle cause the unstimulated portion of the large intestine to bulge outward into baglike sacs called haustrations.

Large Intestine
The iliocecal sphincterThe ileum is the last (and longest) portion of small intestine. It empties into into the cecum (the first part of the "large intestine") at the iliocecal junction. The iliocecal sphincter is a ring of invountary smooth muscle at this junction, controlling the passage of digestive contents from the small intestine to the large intestine.
The iliocecal valve is an involuntary smooth muscle sphincter located between the ileum (small intestine) and the secum (portion of large intestine). Its function is to prevent backflow or reflux into the ileum.
