2. What is released form bone, when it is broken down, for use inside of the body?

3. How does the body replace the minerals that are lost form bone when it is broken down?

Level#2

Bones grow and change. Some cells help build bone tissue. Some cells break down bone tissue. When bone tissue is broken down, some of the minerals inside bones are released into the body for use. However, your body normally replaces those minerals with minerals form the foods you eat. The building up and breaking down of your bones changes the size and shape of your bones as you age.

2. What happens when bone tissue is broken down and how does the body replace the minerals bones lose during this process?

3. Because your bones do not grow at the same time, what does this cause?

Level#3

Bones grow and change. Some cells help build bone tissue. Some cells break down bone tissue. When bone tissue is broken down, some of the minerals inside bones are released into the body for use. However, your body normally replaces those minerals with minerals form the foods you eat. The building up and breaking down of your bones changes the size and shape of your bones as you age. At some point in your life, you may go through "an awkward stage" because of the way your bones grow. The first bones to grow quickly are usually your foot bones. Then, your arm and hand bones grow quickly. Because of this uneven growth, arms, hands, and feet may look too big for the rest of the body. This does not last long. After a while, the rest of the body catches up.

1. Explain what happens when bone is broken down and what the body does to replace the minerals that are lost in this process.

2. Explain what the building up and breaking down of bones causes.

3. Explain what happens as a result of the uneven growth of certain parts of the body.
