Study Notes
Skeletal System
- The skeletal system is made up of bones and joints that provide support, protection, and movement for the body.
- The longest and strongest bone in the body is the femur in the thigh, while the smallest bones are the ossicles in the ear.
Functions of the Skeleton
- The skeleton has four main functions: to support the body, protect vital organs, help the body move, and make blood cells.
- The skeleton supports the body, allowing people to sit upright and stand.
- The bones protect vital organs such as the brain, spinal cord, heart, lungs, and liver.
Bone Structure and Function
- Bones are living tissue with a blood supply, constantly being dissolved and formed, and can repair themselves if broken.
- Calcium is essential for bone health and repair.
- Bones work with muscles and tendons to allow the body to move.
Bone Marrow and Blood Cells
- The bone marrow is the soft tissue inside larger bones where blood cells are made.
- There are different types of blood cells, including red blood cells (carry oxygen) and white blood cells (destroy harmful microorganisms).
- Red blood cells are made in the bone marrow, which is protected by the hard part of the bone.
