Question

How do the systems in our body work together to help us move?

Answer 2

yes

Answer 3

Our bones provide support for our bodies and help form our shape. The skull protects the brain and forms the shape of our face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that protects the heart, lungs, liver, and spleen, and the pelvis helps protect the bladder, intestines. Although they're very light, bones are strong enough to support our entire weight.

Answer 4

Joints occur where two bones meet. They make the skeleton flexible and without them, movement would be impossible.

Answer 5

Muscles are necessary for movement: They're the masses of tough, elastic tissue that pull our bones when we move.
