Something called smooth muscle moves the walls of all hollow organs except the heart. The muscle is called smooth because the microscopic subunits called sacromeres are not in any special arrangement. Skeletal muscle is called striated muscle because these units are in a uniform arrangement that appear as striations when seen under the microscope.
Walls of hollow visceral organs such as your intestines.
Involuntary muscle is muscle that contracts on its own. You do not have to think about contracting it. You find this type of muscle in hollow organs such as the digestive tract. You also find a type of involuntary muscle in the heart.
Smooth muscle is found in all hollow tubes or organs except the heart.
involuntary movement as in food through the intestines.
Smooth muscle is found in hollow visceral organs, like the stomach, intestines, uterus, bladder, and blood vessels/arteries. (Smooth muscle doesn't apply to the heart though, that's cardiac muscle)

Yes, the intestines are lined with smooth muscle tissue to move the food through with contractile waves called peristalsis.
It is called deglutition.
Peristalsis is a wave-like muscle contraction that moves food through the digestive tract. It helps to push food along the esophagus, stomach, and intestines, allowing for the digestion and absorption of nutrients.
Smooth muscle tissue, also known as non-striated muscle, is found in the walls of hollow organs such as the intestines and blood vessels. Unlike skeletal muscle, smooth muscle lacks the characteristic striped pattern (striations) due to its different structure and organization of contractile proteins. Smooth muscle is involuntary and contracts slowly and rhythmically to perform functions like moving substances through the body.
No, the food is moved by the muscle action of the intestines, beginning with the esophagus. The reason that the muscle-action is needed is because the coils of the intestines go in all directions, including upwards.
Your intestines contain a medial layer of smooth muscle. When the smooth muscle in your intestines is innervated this causes contractions of those smooth muscles. This action then propels food through the intestines. This is called peristalsis. So, as far as I know there are no other muscle groups that aide in digestions. There are however, a plethora of chemicals and enzymes that assist in the digestive process.
