Skeletal System Function (Support)
Provides framework for attachment of tissues and organs
Skeletal System Function (Storage)
Calcium (99% of the body’s calcium are in the bones)
Phosphate
Magnesium
Skeletal System Function (Energy Storage)
Adipocytes located in yellow marrow
What kinds of cells do bone marrow produce
Erythrocytes (Red)
Leukocytes (White)
Platelets (Blood Clot)
Skeletal System Function (Leverage)
Muscles pull on bones to produce movement
Skeletal System Function (What do the following bones Protect)
- Ribs
- Skull
- Vertebrate
- Pelvic Bones
Ribs = Heart and Lungs
Skull = Brain
Vertebrate = Spinal Cord
Pelvic Bones = Reproductive Organs
