Esophagus

Definition

Muscular tube approximately 25 cm in length connecting the pharynx to the stomach. It transports food through muscular contractions called peristalsis.

How it works

The esophagus is a passive but active conduit lined with smooth muscles that contract in a coordinated manner to propel food into the stomach through the process of peristalsis. This progression takes approximately 5-10 seconds.

Role

Conveying food from the mouth to the stomach through peristaltic contractions.

Examples

• Solid food passage
• Beverage transit
• Food bolus transport

Recommendations

Avoid lying down immediately after meals to prevent reflux. Limit spicy or fatty foods if experiencing gastric reflux. Maintain good posture during meals to facilitate transit.

Key takeaway

The esophagus transports food into the stomach through peristalsis.
