Study Notes
- Food enters the chicken's beak and goes to the crop for moistening and softening before moving to the proventriculus, the true stomach.
- The proventriculus secretes digestive juices and is attached to the gizzard, where food is ground into smaller pieces.
- Nutrients are absorbed in the small intestine and circulated throughout the chicken's body via blood vessels.
- Waste materials, including urine and feces, are excreted through the vent after digestion in both the small and large intestines.
- The liver acts as a 'chemical factory' for metabolizing important substances, while the lungs play a crucial role in gas exchange and maintaining body temperature.
- Chicken body parts serve various functions: beak for eating and defense, comb and wattles for cooling blood, ear lobes for hearing, eyes for vision, feathers for protection, wings for limited flight, tail for balance, feet for walking and fighting, and cloaca as a common space for waste elimination.
- Chickens produce urine with uric acid, which is excreted along with feces through the cloaca due to the absence of a bladder or urethra.
- Chickens have a unique digestive system without stomachs, relying on food storage in the crop and digestion in the proventriculus and gizzard.
