Bones provide support, protection, and
movement and also play a role in calcium
balance.

Skeletal System
Integumentary System
Vitamin D, activated
in the skin, plays a
role in calcium
absorption and
availability for
bone matrix.
Muscular System
Muscles pull on
bones to cause
movement.
Nervous System
Proprioceptors
sense the position of
body parts. Pain
receptors warn of
trauma to bone.
Bones protect the
brain and spinal cord.
Endocrine System
Some hormones
act on bone to help
regulate blood
calcium levels.
Cardiovascular System
Blood transports
nutrients to bone
cells. Bone helps
regulate plasma
calcium levels,
important to heart
function.
Lymphatic System
Cells of the immune
system originate in
the bone marrow.
Digestive System
Absorption of
dietary calcium
provides material
for bone matrix.
Respiratory System
Ribs and muscles
work together in
breathing.
Urinary System
The kidneys and
bones work together
to help regulate blood
calcium levels.
Reproductive System
The pelvis helps
support the uterus
during pregnancy.
Bones provide a
source of calcium
during lactation.
