2. Skeletal
• Frame work - support
• Protection
• Movement
• Red blood cell production
• Storage of minerals
3. Muscular
• Provide a pulling force to
create movement
• Involuntary muscles
• Voluntary muscles
• Muscles need nervous
stimulus
• Need a great supply of blood
keeping a constant supply of
02 and energy
4. Nervous
• The brain, spinal cord and
nerve branches
• Controls all bodily movements
• The brain receives sensory
input from the external
environment and internal
environment
• Works with the endocrine
system to monitor and
maintain other bodily systems
5. Endocrine
• Glands and cells - Produce
chemicals called hormones
• Circulate in the blood and
other bodily fluids
• Maintain our internal
environment
• Long term effects - Growth,
puberty and reproductive
activity
• Close links with the nervous
system
6. Cardiovascular
• Heart
• Pumps blood around the body
• Supplies the body with oxygen
and nutrient rich blood
• Waste products are removed
when the blood leaves
• Transportation - blood,
nutrients, hormones and
immune cells
7. Respiratory
• The movement of air moving into
and out of the lungs
• Volume and pressure change
within the two cavities of the
body - Thoracic and abdomen
• Deep inside the lungs gaseous
exchange takes place
• 02 inhaled C02 exhaled
• Secondary function - Vocilisation
8. Skin, hair, nails
• Outer protective layer
• physical injury,
microorganisms and radiation
• regulates body temperature
• Fat under the skin acts as an
insulator and shock absorber
9. Lymph and immunity
• Provides residence to threats
including infectious diseases
and malfunction of internal
processes
• Distributes nutrients and
removes waste
• Delivers immunity - white
blood cells when needed
10. Digestive
• 9 metres of tubing
• Mouth - anus
• Chops up food, stores and
digests it, eliminates waste,
passes nutrients to the liver
• Good function of the digestive
system relies on the immune
and nervous system
11. Urinary
• Urine eliminates waste from
the blood
• Urine is formed by the kidneys
• Urine production is controlled
by hormones
• Influenced by blood flow and
pressure, intake of water, fluid
loss, nutrients, temperature,
sleeping and walking
12. Reproductive
• Differs dramatically from male to female
• Is not vital for maintaing life
• production of sperm is continual and
production of eggs in females is
cyclical
• links - endocrine system
