Verified step by step guidance

Begin by identifying the primary functions of the digestive system. The digestive system is responsible for breaking down food into smaller components that can be absorbed into the bloodstream.

Consider the process of digestion, which includes ingestion, mechanical and chemical breakdown of food, absorption of nutrients, and elimination of waste.

Focus on the absorption of nutrients, which occurs primarily in the small intestine. This is a key function of the digestive system, where nutrients from digested food are absorbed into the bloodstream.

Compare the listed options with the known functions of the digestive system. Production of red blood cells, regulation of body temperature, and transmission of nerve impulses are not directly related to the digestive system.

Conclude that the absorption of nutrients is the correct function of the digestive system, as it directly involves the processing and uptake of essential nutrients from food.
