The human alimentary canal is a system of tubes and organs that carry food and nutrients throughout the body. The alimentary canal begins with the mouth, where food is ingested and mixed with saliva to form a bolus. The bolus then travels down the esophagus, which is a long, muscular tube that connects the mouth to the stomach. The stomach is a J-shaped organ that secretes gastric juices, which help to break down food into smaller molecules.
The contents of the stomach are then expelled from the body through the stomach outlet. The partially digested food then moves into the small intestine, which is the longest part of the digestive tract. The small intestine is where most of the nutrients from food are absorbed into the bloodstream. The waste products from digestion are then expelled from the body through the rectum
