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.

Where is the muscularis located?
Assuming you mean muscularis, it's a part of the layers found around our Gastrointestinal system and other systems in our body (Reproductive tract etc). The 4 layers are: 1. mucosa (epithelial layer) 2. submucosa 3. muscularis 4. serosa Muscularis has both longitudinal and circular muscle layers (in the GI tract this is smooth muscle which is used for peristalisis, haustration, etc). Muscularis layer is contractile and used in the GI tract for moving food through the system, or in the reproductive tract for contractions for birth, etc. Hope this helps?
