DIGESTIVE SYSTEM AND DIGESTION IN HUMANS

DIGESTIVE SYSTEM AND DIGESTION IN HUMANS.
Organs that are involved with feeding in humans constitute the digestive system.

Digestive System and Associated Glands

Human digestive system starts at the mouth and ends at the anus
This is the alimentary canal
Digestion takes place inside the lumen of the alimentary canal
The epithelial wall that faces the lumen has mucus glands (goblet cells)
These secrete mucus that lubricate food and prevent the wall from being digested by digestive enzymes
Present at specific regions are glands that secrete digestive enzymes
The liver and pancreas are organs that are closely associated with the alimentary canal
Their secretions get into the lumen and assist in digestions
