Answer: (C)

Verified step by step guidance

1. Begin by identifying the primary functions of the digestive system. The digestive system is responsible for breaking down food into nutrients, absorbing these nutrients into the bloodstream, and eliminating waste products.
2. Consider the mechanical and chemical breakdown of food. This involves processes like chewing (mechanical) and enzymatic action (chemical) to convert food into absorbable forms.
3. Examine the absorption of nutrients. After food is broken down, the digestive system absorbs nutrients through the walls of the intestines into the bloodstream.
4. Evaluate the production of hormones. The digestive system does produce certain hormones, such as gastrin, which help regulate digestive processes.
5. Finally, assess the regulation of body temperature. This is not a function of the digestive system; body temperature regulation is primarily managed by the integumentary and nervous systems.
