As per the bolus meaning medical term, it is a food ball that travels at a slow pace due to the coordinated contraction and relaxation of the smooth muscles in the alimentary canal. The coordinated movement of the food particles helps us digest food without any hassle or interruption. The alimentary canal can carry more than one bolus at a time. In fact, the undigested food particles or faeces form the bolus and move in the large intestine.
