Swallowing

The process of moving food from the mouth to the stomach.

Definition

The act of swallowing chewed food or liquids. It is a complex process involving the throat and esophagus to transport the food bolus to the stomach.

How it works

Swallowing is a semi-voluntary reflex mechanism divided into three phases: the oral phase (voluntary), the pharyngeal phase (reflex), and the esophageal phase (peristaltic). It ensures that food moves correctly from the mouth to the stomach without entering the airways. Coordinated muscles and cranial nerves control this complex process. A swallowing dysfunction can lead to difficulty eating or drinking.

Role

Safely transport chewed food from the mouth to the stomach.

Examples

  • Swallowing water
  • Swallowing bread
  • Swallowing soup
  • Ingesting tablets

Recommendations

Swallow slowly and progressively after thorough chewing. Remain seated or standing for 30 minutes after meals. Drink small amounts of water to facilitate swallowing if necessary.

Key takeaway

Proper swallowing prevents aspiration and ensures correct passage of food to the stomach.
