Integumentary Functions

• Forms the external body covering

• Protects deeper tissue from injury

• Regulates body temp

• Synthesizes vitamin D

• Location of cutaneous nerve receptors

Skeletal Functions

• Protects/Supports body organs and soft tissue

• Proves muscles attachment for movement

• Binds bones together

• Site of blood formation

• Stores inorganic salts (like calcium)

Muscular Functions

• Allows for locomotion

• Maintains posture

• Produces heat

Nervous Function

• Fast acting control system

• Responds to internal/external changes

• Activates muscles and glands using signals

Endocrine Functions

• Secretes chemicals called Hormones

• Hormones effect: Growth, Reproduction, and Metabolism

Cardiovascular Functions

• Transports materials in body via blood pumped by the heart

• Materials include: Nutrients, Oxygen, Carbon Dioxide, and Wastes

Lymphatic Functions

• Defends against infections by removing disease causing things

• Disposes of fatty debris away from the digerstive organs and into the blood vessels

Respiratory Functions

• Moves air in/out of lungs

• Echanges gasses between blood and air

• Keeps blood supplied with oxygen

• Removes CO2 from blood

Digestive Functions

• Breaks down food into smaller particles

• Allows nutrients to be absorbed in the blood

• Eliminates all non-digestible things

Urinary Functions

• Eliminates waste from the blood in the form of urine

• Maintains acid to base balance

• Regulation of: Water and Electrolytes

Reproductive Functions

• Produce/maintain sperm cells and transfer them to the female reproductive tract

• Produces offspring
