Which organ is made of three layers of muscles that continue mechanical digestion?
A
stomach
B
liver
C
anus
D
esophagus
Explanation: 

Detailed explanation-1: -The majority of the digestive tract is composed of two muscular layers to allow for peristalsis-that is, the movement of food. The stomach, however, is composed of three layers, and is designed to account for mechanical digestion.

Detailed explanation-2: -After passage through the esophagus, the bolus will enter the stomach and undergo mechanical and chemical digestion. Mechanical digestion in the stomach occurs via peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus, termed propulsion.
