Verified step by step guidance1
Understand the primary functions of the stomach in the digestive system. The stomach is a muscular organ that plays a crucial role in digestion.
Recognize that the stomach's main function is to break down food into a semi-liquid form called chyme, which is achieved through mechanical and chemical processes.
Identify the chemical processes involved in the stomach's function. The stomach secretes digestive enzymes, such as pepsin, and hydrochloric acid (HCl) to aid in the breakdown of proteins and to create an acidic environment.
Differentiate the stomach's functions from those of other organs. For example, insulin production is a function of the pancreas, nutrient absorption primarily occurs in the small intestine, and toxin filtration is a function of the liver and kidneys.
Conclude that the correct function of the stomach, as listed in the options, is 'Secreting digestive enzymes and hydrochloric acid,' which aligns with its role in digestion.
