Bones provide
support for our
bodies and help form
our shape.
Bones protect internal
organs from injury by
covering and
surrounding them.
Although they're
very light, bones are
strong enough to
support our entire
weight.
Your ribs protect your
lungs and heart, the
bones of your vertebral
column (spine) protect
your spinal cord, and the
bones of your cranium
(skull) protect your
brain.
SUPPORT
PROTECTION
Bones facilitate
movement by serving
as points of attachment
for your muscles.
Some bones serve as a
support for the
muscles, others
transmit the forces
produced when your
muscles contract.
MOVEMENT
Bones in the skeleton
contain bone marrow
which produces red
blood cells, white
blood cells and
platelets.
Examples of bones that
contain marrow are
the pelvis, sternum,
humerus and femur.
PRODUCTION
Bones store
minerals such as
calcium, iron,
potassium and
phosphorous and
release them into
the blood when the
body needs to use
them.
