Digestive System Quiz

Digestive Tract Overview

• The first part of the digestive tract is the mouth.
• The esophagus is often referred to as the "food tube" because it transports food from the mouth to the stomach.

Functions of the Esophagus

• The primary function of the esophagus is to convey food through muscular contractions called peristalsis, facilitating its movement toward the stomach.

Components of the Mouth

• The mouth consists of several parts:
  • Lips
  • Cheeks
  • Tongue
  • Hard and soft palates
  • Salivary glands

Anatomy of the Stomach

• The stomach has a specific topography which includes:
  • Fundus: the upper bulge
  • Body: the main central region
  • Antrum: the lower part leading to the pylorus

Biliary System Function

• The biliary system's primary function in digestion is to produce and transport bile, which aids in the emulsification and digestion of fats.

Food Mixing Process

• The organ responsible for mixing food with saliva in the digestive process is the mouth, particularly facilitated by the action of the tongue.

Stomach’s Tissue Layers

• The stomach is comprised of four layers of tissue:
  • Mucosa: the innermost layer, responsible for secretion
  • Submucosa: contains blood vessels and nerves
  • Muscularis: responsible for the stomach's contractions
  • Serosa: the outer protective layer
