Integumentary System Interactions
Reproductive System
Urinary System
• Skin protects urinary organs;
excretes salts and some
nitrogenous wastes in sweat
• Urinary system activates
vitamin D made by
keratinocytes; disposes of
nitrogenous wastes of skin
metabolism
Nervous System
• Skin protects nervous system
organs; cutaneous sensory
receptors located in skin
• Nervous system regulates
diameter of blood vessels in skin;
activates sweat glands,
contributing to thermoregulation;
interprets cutaneous sensation;
activates arrector pili muscles
• Skin protects reproductive
organs; highly modified sweat
glands (mammary glands)
produce milk. During pregnancy,
skin stretches to accommodate
growing fetus; changes in skin
pigmentation may occur
Endocrine System
• Skin protects endocrine
organs
• Androgens produced by the
endocrine system activate
sebaceous glands and help
regulate hair growth;
estrogen
helps maintain skin hydration
Skeletal System
• Skin protects bones; skin
synthesizes vitamin D bones
need for normal calcium
absorption and deposit of bone
(calcium) salts which make bones
hard
• Skeletal system provides support
for the skin
Respiratory System
• Skin protects respiratory organs
• Respiratory system furnishes
oxygen to skin cells and removes
carbon dioxide via gas exchange
with blood
Muscular System
• Skin protects muscles
• Active muscles generate large
amounts of heat which
increase blood flovv to the skin
and may promote activation of
sweat glands of skin
Cardiovascular System
• Skin protects cardiovascular
organs; prevents fluid loss from
body surface; serves as blood
reservoir
• Cardiovascular system transports
oxygen and nutrients to skin and
removes wastes from skin;
provides substances needed by
skin glands to make their
secretions
Digestive System
• Skin protects digestive
organs; provides vitamin D
needed for calcium absorption
• Digestive system provides
needed nutrients for the
skin
Immune System
• Skin protects lymphatic organs;
prevents pathogen invasion
• Lymphatic system prevents
edema by picking up excessive
leaked fluid; immune system ·
protects skin cells
