what is the crop?

Answer 17

temporary storage area

Question 18

Bird digestive system:
what is the proventriculus?

Answer 18

where the digestive enzymes and hydrochloric acid are added

Question 19

Bird digestive system:
what happens in the ventriculus (gizzrd)?

Answer 19

where mechanical digestion happens

Question 20

Bird digestive system:
where is the two ceca located?

Answer 20

in between the small and large intestine

Question 21

Bird digestive system:
what happens in the two ceca?

Answer 21

water is reabsorbed and food is fermented
