  • The digestive system of the human body is made up of the gastrointestinal tract and additional digestive organs (the tongue, salivary glands, pancreas, liver, and gallbladder).
  • In order for food to be absorbed and incorporated into the body, it must first be broken down into smaller and smaller components during digestion.
  • Cephalic, gastric, and intestine phases make up the three stages of the digestive process.
  • Gastric gland secretions in reaction to the sight and smell of food start the initial stage of digestion, known as the cephalic phase.
