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

Options

A. Locomotion
B. production of erythroctyes
C. storage of minerals
D. production of body heat

Answer

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

### Step-by-Step Solution:

1. **Understand the Functions of the Skeletal System**:
- The skeletal system has several key functions, including providing support and structure to the body, facilitating movement (locomotion), protecting vital organs, producing blood cells, and storing minerals.

2. **Evaluate Each Option**:
- **Option 1: Locomotion**: This is a function of the skeletal system as it provides the framework for muscles to attach and facilitate movement.
- **Option 2: Production of Erythrocytes (Red Blood Cells)**: This is also a function of the skeletal system. The bone marrow, found within certain bones, is responsible for producing erythrocytes.
- **Option 3: Storage of Minerals**: The skeletal system stores essential minerals such as calcium and phosphorus, making this option a function of the skeletal system.
- **Option 4: Production of Body Heat**: This is not a function of the skeletal system. Body heat is primarily produced by metabolic processes in muscles and organs, not by the skeletal system.

3. **Identify the Correct Answer**:
- Based on the evaluation, the option that is not a function of the skeletal system is **Option 4: Production of Body Heat**.

### Final Answer:
The correct answer is **Option 4: Production of Body Heat**.
