Answer the following question in your words.
Which are the various reasons due to which our bones might break?
Solution
Bones are structures that are hard and non-flexible. The chances of the breaking of bones occur if the bones are weak. There are several reasons why bones may weaken and break:
- Certain disorders can weaken and break bones. For example, osteoporosis and arthritis are disorders that cause bone deterioration.
- Deficiency of minerals such as calcium and vitamin D.
- Certain stressors or injuries can cause bone fractures.
- Bone loss occurs with age, making them more frail.
- Alcohol and smoking also have a deleterious impact on bones and their density.
