3 Activity Test your heart rate

4 Organ Systems work together The bodys organ systems work together to carry out all the functions that are vital for survival

5 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

6 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

7 Fun Fact If you lined up all of your blood vessels from end to end, they would form a tube over km long!! Mental ability is increased and improved with physical activity (the mind and body are dependent on each other)
