Integumentary
• Organs and Tissues: hair, skin, nails
• Function: Provides protection, Regulates
temperature, Prevents water loss, Produces
Vitamin D
• Interactions:
• Nervous system: stimulus response
• Excretory: protects against dehydration, releases
sweat and gases
• Cirulatory: regulates body temperature
• Common Disorders: Acne, rashes, sunburns

Heat rash begins with excessive perspiration, usually in a hot,
humid environment. The perspiration damages cells on the
surface of the skin, forming a barrier and trapping sweat
beneath the skin, where it builds up, causing the characteristic
bumps. As the bumps burst and sweat is released, you may feel
the prickly, or stinging, sensation that gives this condition its
common name.
Skeletal
• Organs and Tissues: bones, cartilage, ligaments
(connects bones to bones), and joints
• Functions:
•
•
•
•
Provides protection and support
Allows body movement
Produces blood cells (red and white)
Stores minerals and fat
• Interactions: Muscular System to enable movement.
• Common Disorders: Osteoporosis, Scoliosis

Circulatory
• Organs and Tissues: heart, blood vessels & blood
• Functions:
• Transports nutrients, waste products, gases, and
hormones throughout the body
• Plays a role in the immune response and the
regulation of body temperature
• Interactions: transportation for digestion,
excretory, respiratory, and endocrine.
• Common Disorders: Heart Attack, Hypertension,
stroke, blood clots
Blood flow from arteries to veins

Nervous
• Organs and Tissues: neuron (smallest unit),
brain and spinal cord.
• Function: Respond to internal and external
stimuli
• Interactions:
– Muscular: movement
– Skeletal: movement
– Integumentary: movement and response
• Common Disorders: Multiple Sclerosis (MS),
Alzheimer's, & paralysis
CNS and PNS
• Organs and Tissues: neuron, central nervous
system (brain & spinal cord) and peripheral
nervous system (nerves & sensory receptors)

Endocrine
• Organs and Tissues: glands, such as the pituitary,
that secretes hormones
• Functions:
• A major regulatory system that influences
metabolism, growth, reproduction
