It's involuntary, we cannot voluntary control our digestion, or the functions of our organs
Yes, you do not have control over your bowels unless you are using the bathroom for a number 2.
Involuntary, as we are not conscious of pushing food through the digestive system.
We cannot order our intestines to work or voluntarily control it's processes.

The vast majority is involuntary. The lower bowels can be controlled, but very limited in nature.
These muscles are called the tunica muscularis.
muscular tissue (specifically, smooth muscle)
the nutrients enter the blood in the small intestine. The lining of the small intestine is called the villi, that is were the blood is absorbed into the bloodstream
No, the length increases. When you are alive, the muscles are contracted in folds, and when you die, these folds relax, expanding the small intestine.
It starts in your mouth. Then you swallow and it goes down your gullet into your stomach. The liver takes out the minerals.Then it goes down into the small intestine. The large intestine around the small intestine takes out the healthy stuff.It then goes through your small intestine and out through the anus.
Ileum (part of the small intestine) Iris (in the eye) Intercostal muscles (the small muscles between the ribs) Islets of Langerhans (part of the pancreas)
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.
they squeez it through to the large intestine
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
Intestines are lined with what are called smooth muscle tissue. These muscles differ primarily from the muscles attached, for example, to your joints in that their movement is rhythmic and involuntarily controlled. (The heart is another example of smooth muscle movement.) It is this rhythmic, involuntary contraction that moves food through the intestines.
