Question

Digestive system has ............. muscles.

• A. Voluntary
• B. Involuntary
• C. Cardiac
• D. All of the above

Answer 1

The correct option is B Involuntary

• The large, hollow organs of the digestive tract contain a layer of involuntary muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis (involuntary muscle movement of the Digestive system).
• Involuntary muscle is a muscle that contracts without conscious control and found in walls of internal organs such as stomach and intestine and bladder and blood vessels.
  So, the correct answer is 'Involuntary'.
