Which of the following is not a function of the skeletal system

Options

A. Production of erythrocytes
B. Storage of minerals
C. Production of body heat
D. Locomotion

Answer

To determine which of the following is not a function of the skeletal system, we will analyze each option provided:

1. **Production of erythrocytes**: The skeletal system, specifically the bone marrow found within certain bones, is responsible for the production of erythrocytes (red blood cells). Therefore, this is indeed a function of the skeletal system.

2. **Storage of minerals**: The skeletal system serves as a reservoir for minerals, particularly calcium and phosphate. Bones store these minerals and release them into the bloodstream as needed. Hence, this is also a function of the skeletal system.

3. **Production of body heat**: The skeletal system does not play a direct role in the production of body heat. Body heat is primarily generated by metabolic processes in muscles and other tissues, not by the skeletal system. Therefore, this is not a function of the skeletal system.

4. **Locomotion**: The skeletal system provides the framework for movement by serving as attachment points for muscles. It plays a crucial role in locomotion, allowing the body to move. Thus, this is a function of the skeletal system.

Based on this analysis, the option that is not a function of the skeletal system is:

**Answer**: The production of body heat.
