Final answer:
Salivary glands, liver, and stomach lining are parts that assist with secretions for breaking down food. Salivary glands produce digestive enzymes, the liver secretes bile, and the stomach lining releases gastric juices. The kidneys are not involved in food digestion. option c is the correct answer.
Step-by-step explanation:
The parts that assist with secretions to help breakdown food include salivary glands, liver, and the stomach lining. The salivary glands produce saliva containing enzymes like salivary amylase for digesting carbohydrates. The liver secretes bile, assisting in the emulsification of fats, whereas the stomach lining secretes gastric juices which include hydrochloric acid and enzymes like pepsin for the digestion of proteins.
The liver and pancreas specifically release their secretions into the small intestine. Hormones such as secretin and gastrin facilitate the release of these digestive enzymes and bile. The gallbladder stores bile and releases it into the small intestine, where it is vital for lipid digestion.
It is important to note that although the kidneys are involved in the excretory system, they do not play a direct role in the breakdown of food.
