Often asked: Which Of The Following Is A Feature Of The Muscular Actions Of Digestion?

What are the muscular actions of digestion?

The large, hollow organs of the digestive tract contain a layer of 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.

What is the most muscular part of the digestive system?

Stomach. The stomach is a muscular organ responsible for storage, initiating the breakdown of nutrients, and passing the digesta into the small intestine.

Which of the following is a feature of peristalsis?
