Integumentary System
Chapter 5
Skeletal system provides support for body organs including the
skin
Skin provides vitamin D needed for proper calcium absorption
and use
Muscular System
Chapters 9–10
Skeletal system provides levers plus ionic calcium for muscle
activity
Muscle pull on bones increases bone strength and viability;
helps determine bone shape
Nervous System
Chapters 11–15
Skeletal system protects brain and spinal cord; provides depot
for calcium ions needed for neural function
Nerves innervate bone and joint capsules, providing for pain
and joint sense

Homeostatic Interrelationships Between the
Skeletal System
and Other Body Systems
Endocrine System
Chapter 16
Skeletal system provides some bony protection; stores calcium
needed for second-messenger signaling mechanisms
Hormones regulate uptake and release of calcium from bone;
promote long bone growth and maturation
Cardiovascular System
Chapters 17–19
Bone marrow cavities provide site for blood cell formation;
matrix stores calcium needed for cardiac muscle activity
Cardiovascular system delivers nutrients and oxygen to bones;
carries away wastes
Lymphatic System/Immunity
Chapters 20–21
Skeletal system provides some protection to lymphatic organs;
bone marrow is site of origin for lymphocytes involved in
immune response
Lymphatic system drains leaked tissue fluids; immune cells
protect against pathogens
Respiratory System
Chapter 22
Skeletal system protects lungs by enclosure (rib cage)
Respiratory system provides oxygen; disposes of carbon dioxide
Digestive System
Chapter 23
Skeletal system provides some bony protection to intestines,
pelvic organs, and liver
Digestive system provides nutrients needed for bone health and
growth
Urinary System
Chapters 25–26
Skeletal system protects pelvic organs (urinary bladder, etc.)
Urinary system activates vitamin D; disposes of nitrogenous
wastes
Reproductive System
Chapter 27
Skeletal system protects some reproductive organs by enclosure
Gonads produce hormones that influence the form of the
skeleton and epiphyseal closure
