2 Concept  Is the organ system whose primary function is to support, and protect the body, and to allow the body to move.

3 Functions  Protection: It protecs your internal organs, like the heart that is protected by the ribs or the brain that is protected by the skull.  Storage: The bones stores the minerals that helps your nerves and muscles,.

4  Movement: The bones help you to move, without them you won’t be able to walk, sit, run.  Blood cell formation: Some bones have marrow, that is a material who makes blood cell.

5 Bone structure  Catilage: is a type of connective tissue in the body  Blood vessels: Blood vessels are part of the circulatory system, which passes nutrients, blood, hormones, and other important substances to and from body cells in order to maintain homeostasis

6  Marrow: Bone marrow is a special, spongy, fatty tissue that houses stem cells, located inside a few large bones. These stem cells transform themselves into white and red blood cells and platelets, essential for immunity and circulation.  Compact bone: These tissues differ in how dense the bone is, or how tightly the cells are packed together. The cells of compact bone appear to be tightly packed together into a solid mass. While they are close together, this type of bone is not completely solid.

7  Spongy bone: Spongy bone, also called cancellous or trabecular bone, is one of the two types of calcium tissue that make up bones in the human body.  Epiphyseal line: a plane or plate on a long bone, visible as a line, marking the junction of the epiphysis and diaphysis.

9 Bone Growth  Most bones start out as a flexible tissue called cartilage.  When you were born, you didn’t have much true bone.  As you grew, most of the cartilage was repleaced by bone.

10 Joints  Is the place where two or more bones meet.  Your joints allow your body to move when muscles are contract.  Joints are held together by ligaments.  Ligaments are strong elastics bands of connective tissue.  Cartilage helps cushion the area in a joint where bones are meet.

11 Injuries and disease  Injuries: The bones get injured when they are fractured or broken  Disease: One disease is osteoporosis. Osteoporosis makes the bones more likely to have several fractures.
