Prime objective of this lecture is to present on Digestion and Peristalsis. Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Peristalsis is the squeezing action of muscles that is used to move food along the alimentary canal. When you swallow food, it doesn’t just drop down into your stomach. Muscles contract in a wave-like motion to move the food along through the digestive tract. This muscle movement is called, peristalsis.
