Cartilages are made up of:

Options

A. Calcium phosphate
B. Sodium chloride
C. Chondroitin sulphate
D. Chondroitin

Answer

To answer the question "Cartilages are made up of:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cartilage**:
- Cartilage is a type of connective tissue found in various parts of the body, including joints, the end of ribs, the nose, and the ears. It is known for its flexibility and support.

2. **Composition of Cartilage**:
- The primary component of cartilage is **Chondroitin Sulfate**. This is a complex carbohydrate that is crucial for the formation and maintenance of cartilage.

3. **Role of Chondroitin Sulfate**:
- Chondroitin sulfate provides the necessary structure and flexibility to cartilage. It helps in the resilience and elasticity of the cartilage, allowing it to withstand pressure and stress.

4. **Other Components**:
- While Chondroitin Sulfate is the main component, cartilage also contains proteins and other substances that contribute to its structure, but they are not as significant as Chondroitin Sulfate.

5. **Conclusion**:
- Therefore, the answer to the question is that cartilage is primarily made up of **Chondroitin Sulfate**.
