Smooth muscle is controlled by the autonomic nervous system, which includes both sympathetic and parasympathetic divisions. The sympathetic nervous system typically causes smooth muscle contraction, while the parasympathetic nervous system usually promotes relaxation of smooth muscle. Additionally, hormones and local factors can also influence the contraction and relaxation of smooth muscle.
The smooth muscle in the iris of the eye controls the size of the pupil, which regulates the amount of light entering the eye. When this muscle contracts, the pupil constricts, reducing the amount of light that enters the eye, and when it relaxes, the pupil dilates to allow more light in.
No, the autonomic nervous system controls smooth muscle, such as organs and some glands.

Smooth tissue refers to a type of tissue that lacks striation and is typically found in organs like blood vessels and the digestive tract. Muscle tissue encompasses three types: skeletal muscle, cardiac muscle, and smooth muscle. Smooth tissue is a specific type of muscle tissue known as smooth muscle tissue.
This statement is incorrect. Muscle tissue can be either voluntary (skeletal muscle) or involuntary (smooth and cardiac muscle). Additionally, muscle cells (myocytes) have numerous mitochondria to provide energy for muscle contractions.

Smooth muscle is found in your internal organs and one of the things it controls is digestion...
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.

No, and the muscle that controls the movement is the piloerector muscle. See piloerector which are smooth muscle (involuntary)
The smooth muscle in the iris of the eye controls the size of the pupil, which regulates the amount of light entering the eye. When this muscle contracts, the pupil constricts, reducing the amount of light that enters the eye, and when it relaxes, the pupil dilates to allow more light in.
The smooth muscle, which is innervated by the sympathetic nervous system, controls the diameter of the blood vessel, and it plays an important role in blood pressure.

Smooth muscle is mostly in the afferent branch going from the arteries to the arterioles. The body controls where blood will flow by controlling the vessel diameter. An increase in sympathetic tone constricts smooth muscle, decreases blood vessel diameter, and limits blood flow.
