Introduction

The proventriculus is also referred to as the muscular stomach. It is connected by the isthmus to the gizzard.


Functional Anatomy

  • A storage organ in fish and flesh eating birds
  • Appropriate to a soft diet
  • Secretes digestive enzymes
  • Contacts the left lobe of the liver ventrally
  • Lies on the midline of the bird
  • Spindle/fusiform shaped
  • Roughly 4cm long


Histology

  • Mucous cells
  • Columnar epithelium
  • Papillae- through which collecting ducts from glands run
  • Lamina propria run into the papillae
  • Hydrochloric acid and pepsin produced
  • Glands in the submucosa
