Understanding which foods are high in calcium can help you ensure that you are encouraging your kids to get enough calcium in their diet by choosing calcium rich foods such as milk, cheese, and yogurt. Remember that children should eat 3 age-appropriate servings of dairy products per day (4 servings per day for adolescents) or the equivalent to get enough calcium in their diet.

| Muscular System |
The muscular system is the body's network of tissues that controls movement both of the body and within it (such as the heart's pumping action and the movement of food through the gut). Movement is generated through the contraction and relaxation of specific muscles.
The muscles of the body are divided into two main classes: skeletal (voluntary) and smooth (involuntary),
Skeletal muscles are attached to the skeleton and move various parts of the body. They are called voluntary because a person controls their use, such as in the flexing of an arm or the raising of a foot.

| Human Skeletal |
Inside every person is a skeleton, a sturdy framework of 206 bones. The skeleton protects the body's organs, supports the body, and provides attachment points for muscles to enable body movement. The human skeleton consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles and cartilage. It serves as a scaffold which supports organs, anchors muscles, and protects organs such as the brain, lungs and heart. Bones also produce blood cells and act as a storage site for minerals such as calcium and phosphorus.
