Why do children recover faster than adults from bone fractures?

Options

A. The bones of children are still cartilage
B. The bones of children have high immunity
C. The bones of children are still growing
D. Children gets much more rest than an adult when they are injured

Answer

### Step-by-Step Solution:

1. **Understanding Bone Fractures**: When a bone is fractured, it means that the bone has broken or cracked due to stress or injury. Recovery from a fracture involves healing of the bone tissue.

2. **Growth of Children's Bones**: Children's bones are still growing and developing. This means that their bones have not yet reached full maturity. This growth process allows for quicker healing.

3. **Periosteum in Children's Bones**: The periosteum is a dense layer of vascular connective tissue that surrounds the bones. In children, the periosteum is thicker and more active, which aids in the healing process.

4. **Vascular Connective Tissue**: Children's bones have a dense layer of vascular connective tissue, which means there is a rich supply of blood vessels. This increased blood flow helps deliver nutrients and cells necessary for healing.

5. **Cell Division**: The tissues in children's bones are still dividing and growing. This active cell division means that when a fracture occurs, the body can quickly generate new bone cells to repair the fracture.

6. **Comparison with Adults**: In adults, the bones are fully developed and the periosteum is thinner. Additionally, the rate of cell division slows down as people age, which means that healing from fractures takes longer.

7. **Conclusion**: Therefore, children recover faster from bone fractures than adults due to their growing bones, thicker periosteum, and higher levels of vascular connective tissue, which all contribute to a more efficient healing process.
