What is the term for the "tube" running through the body, connecting the human mouth to the anus?

The term for the "tube" that runs through the body, connecting the human mouth to the anus, is known as the alimentary canal. This term encompasses the entire digestive tract, which includes structures such as the esophagus, stomach, intestines, and rectum, functioning to process food from ingestion to excretion.

Understanding this term is vital as it relates to how the body handles nutrients and waste products during digestion. The alimentary canal plays a crucial role in breaking down food, absorbing nutrients, and eliminating waste, which is core to understanding many aspects of human health and nutrition relevant to chiropractic care.
