Concepts Used:
Digestion and Absorption - Alimentary Canal
Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
