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.
Whereas the rest of the alimentary canal only has two muscular layers, longitudinal and circular, for peristalsis, the stomach has an additional oblique layer that permits it to churn and pummel the food.

DO PLANTS HAVE CIRCULAR DNA
DNA in prokaryotes is circular and in the cell itself, while the DNA of eukaryotes is coiled and in the nucleus (organelle) of the cell.
Circular and Longitudinal muscles.
An inverse is NOT called a circular function. Only inverse functions that are circular functions are called circular functions for obvious reasons.
Some muscles appear to run in different directions because that is their inclinations. The direction may be circular or longitudinal.
"Circular functions" is basically another name for "trigonometric functions".
between the circular and longitudinal muscle layers
circular functions
When the circular muscles contract, they make the worm skinnier. When the longitudinal muslces contract, they make the worm shorter. This series of movements allows for the worm to move forward.
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
circular motion
Yes, water waves are a combination of both longitudinal and transverse motions.
