| Organ | Anatomical Location | Primary Digestive Role |
|---|---|---|
| Crop | Base of neck | Expandable pouch for temporary storage up to 12 hours |
| Proventriculus | Glandular stomach | Secretes gastric acid and digestive enzymes |
| Gizzard | Muscular stomach | Physical grinding and crushing of feed particles |
| Ceca | Blind pouches | Bacterial fermentation of remaining undigested feed |
| Cloaca and Vent | Terminal opening | Combines and expels digestive waste and white urine |
When you use it
Use to trace feed movement and identify functions of specialized organs in poultry digestion.
Watch out
Chemical digestion with acid occurs in the proventriculus, while physical grinding occurs in the muscular gizzard.
