1. Linking the 3 systems together
Cardiovascular, Respiratory & Muscular

2. Task 1-Draw, Label and Fully Explain
Draw the Respiratory System
Label each key part of the system
Explain each of the functions during inhalation and expiration

3. The Respiratory System has two main functions
To bring Oxygen into the body
To take carbon dioxide out of the body

4. Recap on the CV system
The Heart is a pump, which pushes blood throughout many blood vessels in the body
Blood being pushed around the body has 2 main functions
To supply the body with oxygen
Remove waste products such as carbon dioxide
Blood vessels run throughout the body to allow blood to travel everywhere

5. Regular Exercise and the Cardio Vascular System
Decreased resting Heart Rate
Heart rate recovery rate improves
Increased stroke volume (amount of blood pumped per beat)
Better Cardiac output (amount of blood ejected from the heart each minute)
Reduced blood pressure
Healthy veins and arteries

6. Three types of muscles INVOLUNTARY MUSCLE:
Is found in the body's internal organs. It is called involuntary as it is not under our conscious control.

7. CARDIAC MUSCLE
Is found only in the heart. It is also an involuntary muscle and it never stops working until we die. It pumps blood from the heart around the body

8. VOLUNTARY MUSCLES Also known as skeletal muscles
These muscles are under our conscious control, and is the type of muscle that makes us move

9. How voluntary muscles work
Voluntary muscles produce movement by contracting and relaxing
They get shorter when they contract and longer when they relax again
Voluntary muscles are attached to the bone by tendons

10. EXAMPLE
Muscular contractions shorten the muscle
Bicep bends the elbow
Bicep shortens
Tricep relaxes and lengthens

11. The immediate effects of exercise on the muscular system
Exercise increases the bodies demand for oxygen and glycogen- the muscles need more fuel to function
Extra waste products are created when the muscles work hard- demand for more blood to remove waste products
It is possible for the muscles to work aerobically for a long period of time, but when the demand becomes to great lactic acid builds up leading to cramp
