Which combination best describes the stomach's main school-level digestive roles?
Storing and churning food while beginning substantial protein digestion✓Respuesta correcta
Producing bile and absorbing every nutrient
Performing only mechanical digestion with no chemical action
Compacting undigested material and producing urine
Explicación
The stomach temporarily stores food, churns it, and combines it with acid and enzymes that begin substantial protein digestion. Bile is produced by the liver, so bile production cannot be assigned to the stomach.
