How our Bodies work
Heart Rate Your heart works like a pump, it has a
contracting action followed by a relaxing action
Each time your heart beats, it pumps blood into the arteries causing a pulse
Your pulse indicates how fast or slow your heart is beating
Activity Test your heart rate
Organ Systems work together The body’s organ systems work
together to carry out all the functions that are vital for survival
Example: Hand Look at your hand- it is an example of all
of the systems Skeletal- bones Circulatory- blood vessels Nervous- nerves carrying signals to the
brain Respiratory- oxygen delivered via blood Digestive- nutrients delivered via blood Excretory- wastes removes from tissues
System Interdependence The circulatory system has the job to
transport substances throughout the body; It gets these substances from other organ
systems (ie nutrients, oxygen) But the circulatory system also relies on
nervous system, muscles etc to be able to function
The body could not function without all of its body systems
Fun Fact If you lined up all of your blood vessels
from end to end, they would form a tube over 100 000 km long!!
Mental ability is increased and improved with physical activity (the mind and body are dependent on each other)

Prevention and treatment when illness occurs
Traditional (aboriginal medicine)- Aboriginal peoples believe all plants and
animals have a purpose and are sacred Also put a lot of value in the power of a
person’s spirit and prayer was always used to enhance medicine
Used many ‘sacred’ plants to treat common aliments
Naturopaths continue to use traditional medicine today Strive to find the cause of the illness and
heal that instead of treating symptoms Works over the long term to help the body
heal itself
Vaccines Have helped eradicate certain deadly
diseases Recently have been questioned for
safety and a link to autism This has now been scientifically disproved
Types of vaccines Smallpox- has killed 300-500 million
people and as many as 2 million in 1967 alone
Polio- causes paralysis and possible death, Canada was declared polio free in 1994
Measles- affects18 million people a year (200, 000 die) still contract the disease but worldwide deaths have been decreased by 74%
